SWEET, Christy, R. CALDERON, Laura, M. BARBER, Jerry, R. CROUTHER, Ronald WISSMAN, Lawrence, Y. FEMRITE, Dennis Address for Service: DAVIES COLLISON CAVE, Patent Attorneys, of 1 Nicholson Street, Melbourne 3000, Victoria, Australia Invention Title: Urine collection bags for urinary catheter systems The following statement is a full description of this invention, including the best method of performing it known to us: P 10PERGCP\2002236611 0, spe :Io-28/02/2007 URINE COLLECTION BAGS FOR URINARY CATHETER SYSTEMS TECHNICAL FIELD This invention relates to urine collection bags for urinary catheter systems. 5 BACKGROUND Urinary catheter systems generally include a long, thin, flexible tube (the urinary catheter) that is inserted into the urethra, past the trigone muscle and into the bladder to withdraw urine from the bladder. Urine flows through the catheter and is collected, e.g., in 10 a urine collection bag. Once urine flow stops, or if the bag is filled, the catheter is removed from the bladder. The catheter is generally lubricated to facilitate insertion. In a closed catheter system, the lubricated catheter is supplied inside the urine collection bag with a urethral introducer tip to prevent human contact/contamination of the catheter as it is inserted into the urethra. The introducer tip is inserted into the patient's urethra, and the 15 catheter is advanced out of the bag by sliding the catheter through the bag using the following procedure. Following insertion of the introducer tip, the user stabilizes the introducer tip with the user's non-dominant hand (i.e., the left hand if the user is right handed). Next, using his dominant hand, the user holds the catheter through the bag, with his thumb and index finger, just behind the introducer tip, and advances the catheter slowly 20 into the urethra. The catheter is advanced by the user pinching the catheter with his non dominant hand, while using his dominant hand to retract the bag without retracting the catheter out of the urethra. The user then reduces the finger pressure applied by the non dominant hand, and repeats the preceding step a number of times until the catheter has been advanced into the bladder and urine is flowing into the bag. 25 There is a tendency, during this procedure, for the catheter to slip back into the bag as the user is trying to advance it, causing the user discomfort and frustration. This is in part due to the difficulty of gripping the lubricated catheter through the bag material. Many users of urinary catheters have compromised finger strength, due to spinal cord injuries, which only exacerbates the gripping problem. Also, if the bag is formed of certain 30 materials, moving the bag in this manner may cause a "crinkling" noise that may be embarrassing to the user if the catheter is being used in a public restroom.

P3OPER\GCP\ZO72JXR83 2n gdoc. I fl3/2)9 -2 It is generally desirable to overcome or ameliorate one or more of the above described difficulties, or to at least provide a useful alternative. SUMMARY 5 In accordance with one aspect of the present invention, there is provided a urine collection bag for use in a urinary catheter system including a catheter having an introducer tip for introduction of the catheter into the urethra, the urine collection bag comprising: opposed portions of plastic sheet material that are sealed together around a 10 peripheral edge to define a substantially closed receptacle having an open end through which the catheter can be advanced into the urethra; and joined to the receptacle at the open end, a braking interface tube configured to receive and guide the introducer tip, characterised in that the braking interface tube has a beveled leading edge, wherein the leading edge is inclined rearwardly relative to the 15 direction of advancement of the catheter. Implementations of preferred embodiments of the invention may include one or more of the following features. The leading edge is inclined at an angle of from about 15 to 45 degrees. Facing surfaces of the opposed portions of plastic sheet material include a 20 surface texture. The braking interface tube is formed from a polymer selected from the group consisting of polyvinyl chloride, polyurethanes and silicones. The braking interface tube is formed of a material having a hardness of from about 40 to 80 Shore A. The bevelled leading edge defines an open area, and the braking interface tube is dimensioned and positioned so as to allow a user to place his thumb against a first one of the opposed 25 portions, over the open area, and his index finger on the opposite one of the opposed portions, approximately aligned with the thumb, so that the thumb presses the first opposed portion directly against the catheter tube, while the index finger presses the opposite opposed portion against a lower surface of the braking interface tube, which in turn presses against the catheter tube. The open area is substantially elliptical. 30 P:OPER\GCP\2007200983 Ispa doc.15/10/2008 -3 In some implementations of this preferred embodiment of the invention, the sheet material is a noiseless material, e.g., polyvinyl chloride. Preferred embodiments of the invention also feature closed catheter systems 5 including the urine collection bags described above. The term "overall thickness", when used herein to refer to a textured film, refers to the thickness of the film including the raised areas of the surface texture (e.g., dimension T. in Fig. 4A). If the textured film includes a surface texture having raised areas of 10 different heights, the overall thickness is measured at the highest point on the textured surface.

Seams 14 can be sealed, e.g., by ultrasonic welding or heat sealing. Prior to use, a catheter 40 (shown in phantom lines) resides in the urine collection bag 10. The catheter 40 includes a catheter tube 42 with a first end 44 for insertion into the patient's urethra and a second end 46 through which urine from the bladder flows into the bag 10. The first end 5 44 of the catheter tube 42 includes an introducer tip 47 that resides in a braking interface tube 48 that is welded to the base of the introducer tip 47. The function of braking interface tube 48 will be described in detail below. The second end 46 of the catheter tube 42 includes a rigid, non-deformable stop member 51 designed to prevent the catheter 40 from slipping out of the bag 10 through the interface tube opening 50 when the catheter is in 10 use. A cap 43 is provided to seal the bag before and after use. The receptacle 13 may be substantially "bottle-shaped", i.e., it has an elongated, relatively narrow neck region 15, shoulders 16, and a relatively wide reservoir region 18. The neck region 15 preferably has a width W (Fig. IA) of less than about 5cm, more preferably from about 4 to 6 cm, and a length L of at least about 8 cm, more preferably 15 about 8 to 12 cm. Shoulders 16 are smoothly curved, and preferably have a radius of curvature R of from about 0.25" to 1.03". This shape has been found to generally improve user comfort by minimizing chafing and discomfort that can result from sharp edges and comers. While the receptacle may have any desired volume, the receptacle generally has a volume of at least 1000 cc. 20 WO 02/060361 PCT/USOI/47876 Preferably, as shown in Figs. 4 and 4A, the inner surfaces 20, 22 of the portions It, 12, include a surface texture, e.g., a diamond shaped pattern as shown in Fig. 4. The surface texture provides the inner surfaces with a plurality of depressed areas 24 which have a thickness T that is reduced relative to the overall thickness To of the sheet 5 material. The surface texture of the sheet material serves two purposes. First, the depressed areas 24 function as hinge points, significantly increasing the flexibility of the sheet material. This increase in flexibility is advantageous if the sheet material to be used is inflexible, and/or if it is desired to use a relatively thick sheet material, e.g., for ease of processing or strength considerations. Second, the surface texture improves 10 the ability of the user to grip the catheter through the bag when advancing the catheter as described above in the Background section. As discussed above, it is often difficult for a user to grasp a slippery, lubricated catheter through the sheet material. Providing a surface texture increases the surface area that is available, improving gripping. Moreover, during gripping the depressed areas 24 act as storage pockets to receive the 15 lubricant, and the raised areas in between act as pressure points that grip the catheter. The surface texture is preferably on the inner surfaces 20 and 22 in order to provide this improved gripping; however, the surface texture can be provided on both the inner surfaces and the outer surfaces 28 and 30, or only on the outer surface if the improved gripping feature is not required. 20 The depth of the surface texture, i.e., the difference between To and T, will depend upon the degree of increased flexibility that is desired, which will in turn generally depend on the stiffness of the sheet material prior to imparting the surface texture. The two primary variables that will affect the stiffness of the sheet material are the thickness of the sheet material (T 0 ) and its hardness. The thicker and the harder the 25 material, the stiffer it will be in use. Generally, it is preferred that the surface texture have a depth of at least 25% of the thickness T., and preferably from 40 to 60%. If the plastic sheet material has an initial hardness (prior to imparting the surface texture) of from about 60 to 80 Shore A, and a thickness of from about 5 to 10 mils, the depth will generally be from about 40 to 60%. If increased flexibility is not required, e.g., if a 30 flexible material such as polyethylene is used, the depth of the surface texture need only be sufficient to provide improved gripping. Preferred plastic sheet materials include extrudable thermoplastics such as polyvinyl chloride (PVC), high and low density polyethylenes, and polypropylenes. 7 WO 02/060361 PCT/USOI/47876 PVC is preferred in some implementations, due to its flexibility, softness, ease of processing, and biocompatibility and hypoallergenic qualities. A suitable PVC is 78 Shore A Polyvinyl Chloride PVC 2222 FS/1-78 Clear 0202, commercially available from Alpha Gary corporation. Suitable plastic sheet materials are manufactured with 5 grades of polymer suitable for human contact. Preferably, after the surface texture is imparted the sheet material has a hardness of from about 60 to 85 Shore A, more preferably about 75 to 81 Shore A. The hardness of the material will determine, in addition to its flexibility, the amount of "crinkling" sound that is produced when the bag is manipulated. If the sheet material is too hard, the bag will tend to make an 10 undesirable amount of noise when used, and may be difficult to manipulate. If it is too soft, the material may have a tendency to elongate under a load, thus distorting the accuracy of the bag markings for fluid intake measurement. Some polyethylenes tend to be "noisy" when used in bags. If polyethylene is used, it is preferred that a relatively quiet grade be selected. 15 Generally, preferred sheet materials have a thickness of from about 5 to 10 mils. If the sheet material is too thin, it may be difficult to form seal 14 (seal the edges of the portions to form the receptacle), while if it is too thick it may be difficult to obtain a desired flexibility. A suitable surface texture is shown schematically in Figs. 4-4A. This surface 20 texture is formed of a criss-crossed arrangement of linear depressed areas, creating a pattern of generally diamond-shaped raised areas. Many other surface textures may be used, provided the desired degree of flexibility and/or gripping is provided. Other suitable surface textures can be readily determined by those skilled in the art, and include any texture that can be applied to the surface of a metal roll, including but not 25 limited to squares, rectangles, triangles, ellipses, polygons, circles, crystals, snowflakes. The surface texture may be imparted by extruding the sheet material and then passing it between a set of textured rollers prior to winding it up on a take-up roll, or using any other desired technique. 30 The Braking Interface Tube To use the urinary catheter 40, the introducer tip 47 is inserted into the patient's urethra, and the catheter is advanced out of the urine collection bag 10 by sliding the catheter through the bag using the following procedure. Following insertion of the 8 WO (12/060361 PCT/USO1/47876 introducer tip 47, the user stabilizes the introducer tip with the user's non-dominant hand 102, as shown in Fig. 2. Next, using his dominant hand 100, the user holds the catheter tube 42 through the bag, with his thumb and index finger, about 1 to 2 inches behind the braking interface tube 48 (discussed below), and advances the catheter tube 5 42 slowly into the urethra. As shown in Fig. 2A, the catheter tube 42 is advanced by the user squeezing the catheter tube 42 with his non-dominant hand 102, while using his dominant hand 100 to retract the bag 10 without retracting the catheter tip 44 out of the urethra. The user then reduces the finger pressure applied by the non-dominant hand, and repeats the preceding step a number of times until the catheter has been 10 advanced into the bladder and urine is flowing into the bag. During this procedure, the non-dominant hand grasps the catheter tube 42 using the braking interface tube 48. The braking interface tube 48 includes an opening 50 having a beveled leading edge that is inclined at an angle A (Fig. 3A) of from about 15 to 45 degrees from the horizontal H (a horizontal line taken along the upper surface 52 15 of braking interface tube 48 at the apex X of the beveled leading edge. If the beveled edge is formed by cutting the tube, angle A will typically vary to some extent from the angle at which the tube is cut, due to flattening and distortion of the soft tube during cutting. This beveled leading edge provides a generally elliptical open area 54. When 20 the user grasps the catheter tube 42 with the non-dominant hand, the user places his thumb against the bag portion 11, over either the open area 54 or the upper surface 52, and his index finger on the opposite side of the bag, against bag portion 12, approximately aligned with the thumb. Thus, the thumb presses the bag portion 11 directly against the catheter tube 42, while the index finger presses the bag 12 against a 25 lower surface 56 of the braking interface tube, which in turn presses against the catheter tube 42. When the user desires to stop the movement of the catheter tube, the user presses the thumb and index finger together to squeeze the braking interface tube against the catheter tube. The inventor has found that the beveled geometry of the braking interface tube, and the manner in which it is positioned, allows the user to 30 securely grasp the catheter tube 42 through the bag during step (b), providing a "braking" effect which generally prevents the tube from slipping back into the bag during this step. The ability to effectively brake the catheter tube during advancement improves user comfort and ease of insertion. Also, the beveled edge of opening 50 acts 9 WO 0214160361 PCT/USO1/47876 as a contoured stop to allow complete advancement of the catheter using the textured film, without an abrupt stopping point. This feature maximizes stroke length (the distance the catheter can be moved during a single advancement step) and control of the catheter during the insertion process. 5 The beveled edge of the tube also acts as a leak resistant seat for the small diameter of the deformable stop member 51 when the catheter is completely extended out of the bag. Due to this sealing feature, leakage of fluid out of the introducer tip onto the patient and the patient's clothes or bedding is minimized or eliminated altogether. Due to the presence of lubricant, the deformable stop member 51 can be 10 easily disengaged from the beveled edge when the user desires to do so. A braking interface tube 48 can be provided in a urine collection bag that does not include the textured surfaces described above. However, it is preferred that the bag include both of these features, since the textured surface enhances the braking effect that is provided by squeezing the braking interface tube and the flexible sheet material. 15 Suitable materials for the braking interface tube include resilient thermoplastics such as PVC, polyethylene, polyurethanes, silicones and coextrusions of these materials. A preferred material is PVC, a suitable grade of which is medical grade USP Class VI, commercially available from Alpha Gary Corporation, as product no. 2222C 65. Preferred materials have a hardness of less than about 80 Shore A, more preferably 20 from about 40 to 80 Shore A, and most preferably from about 50 to 70 Shore A. Generally, the tube will have a wall thickness of from about 0.89 to 1.02 mm. Typically, the thicker the wall thickness, the softer the tube material should be. The hardness and wall thickness are selected so that the user can easily pinch the walls of the braking interface tube together with finger pressure to grip the catheter tube as 25 stated above. Using the Closed Catheter System To obtain a urine sample, the catheter 40 is advanced through the braking interface tube 48 and out of the introducer tip 47, as discussed above, and is inserted 30 into the urethra of the patient. The catheter 40 is then gradually moved into the urethra until the catheter reaches the bladder and urine begins to flow into the bag 10. Following use, the bag 10 may be torn at a tear seam 60 at the base of the bag neck on 10 WO 02/060361 PCT/US01/47876 the shoulder. The urine in the bag 10 may then be poured from the bag into a sample collection vessel for analysis. Other embodiments are within the scope of the following claims. 5 For example, if the surface texture tends to render the bag translucent or opaque, it may be desirable to provide a clear window in one or both of portions 11 and 12. (The degree of visibility through the textured film will generally depend on the depth of the texture, the clarity of the plastic and the manufacturing process used.) This may be accomplished by, for example, selectively texturing the film in the 10 machine direction during the film extrusion process. To simplify processing, the window may be in the form of a continuous clear stripe, e.g., longitudinal stripe 200 in Fig. 5 or width-wise stripe 200A in Fig. 5A. This window allows the user to improve his view of his urine and evaluate whether it is too dark, cloudy, or has particulate matter floating in it, indicating that the 15 user should drink more water as a first line of defense against a urinary tract infection (UTI). Having a visual warning can often allow the user to ward off a UTI by taking early countermeasures. An alternative to a clear window or stripe is to texturize only one of the portions 10, 12, and leave the other portion untextured. 20 Moreover, the tear seam 60, shown on the side of the reservoir region 18 in Fig. 1, may be positioned in other areas of the bag, to facilitate draining of urine from the bag. For example, as shown in Fig. 6, a tear tab 202 may be positioned on the neck region 215 of the bag. This positioning allows a pour opening 204 (Fig. 7A) to be provided on the side of the neck region, rather than on the side of reservoir region 18, 25 as would be the case in the embodiment shown in Fig. 1. Preferably, the tear tab 202 is detachably joined to the neck 215 by a recessed groove 201 which allows the tear tab to be smoothly torn towards the user (out of the page, in Fig. 7) to the position shown in Fig. 7A, resulting in pour opening 204. Tearing is initiated at a notch A (Fig. 7). Pour opening 204 generally has a nominal 30 length of from about 0.75 to 1.25 inch, resulting in an opening having a diameter of about 0.45 to 0.8 inch, assuming the opening to be circular (in practice, it is typically somewhat elliptical).

P OPERGCP12(0223661 d, s doc- k/02/2007 - 12 Providing the pour opening on the neck of the bag generally allows the user or a caregiver to drain the bag by holding the reservoir region and tilting the pour opening downward. Using one hand to drain the bag allows a wheelchair-bound patient to use the other hand to hold onto his wheelchair. The positioning of the tear tab on the side of the 5 neck, with the tear direction being away from the patient, allows the patient to use the weight of the urine-filled bag to his advantage, rather than against him as would be the case with other tear tab locations. An alternate arrangement that allows the bag to be drained using one hand is to position the tear tab at the bottom of reservoir region 18. In this case, the user would 10 generally grasp the neck region to drain the bag. The tear tab may have any desired design. Examples of suitable designs that allow easy removal of the tear tab (as shown in Fig. 7A), while preventing in advertant removal and bag leakage, are shown in Fig. 6, 7 and 8-8C. The tear tab may have a hole through which the user may insert his finger to pull the tab, e.g., holes 206 in Figs. 6, 7, 8 and 8C. 15 The tear tab shown in Fig. 8C includes a recessed area 207, to facilitate gripping. Alternatively, the tear tab may include raised ribs or other structures to assist the user in gripping the tab, e.g., ribs 208 in Figs. 8A and 8B. The urine collection bag may also include features designed to make the bag easier to hold during emptying, particularly when the user needs to hold the bag with only one 20 hand. For example, as shown in Fig. 9, the bag may include a tab 210 at its distal end 212, with an opening 214 through which the user can insert one or more fingers to hold the bag during draining. Throughout this specification and claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will 25 be understood to imply the inclusion of a stated integer or group of integers or steps but not the exclusion of any other integer or group of integers. The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or 30 information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
