Abstract

needle (26) is provided that can be used for introducing or aspirating fluids to a patient or as an introducer needle for positioning and inserting a catheter (58), such as a peripheral IV catheter into a patient. The needle (26) can be an introducer needle that extends from the distal end of the catheter during insertion. The needle (26) has an insertion tip with a configuration to assist penetration into a vein (60) with a reduced incidence of injuring the inner surface of the vein or inadvertently passing through side wall of the vein. The needle tip (46) can be formed with a curved distal end surface (54) where the pointed tip (46) is spaced radially inward relative to the outer surface (56) of the needle (26). In another embodiment the needle tip can have a reverse beveled surface (42, 44) having an axial length, angle, and curvature to assist in penetrating the vein with a reduced incidence of transfixing the vein.

Claims (1)

WHAT IS CLAIMED IS:
1. A needle comprising: a body having a longitudinal dimension with a proximal end and a distal end; a lumen extending between said proximal end and said distal end, a first longitudinal side surface, a second longitudinal side surface opposite said first longitudinal side surface; a first bevel surface extending at an angle of 12-22° with respect to the longitudinal dimension from said first longitudinal side surface to said second longitudinal side surface to form a distal tip; a second reverse bevel surface and a third reverse bevel surface on an outer peripheral surface at said second longitudinal side surface and converging to said distal tip and said first bevel surface, said second reverse bevel surface and third reverse bevel surface being oriented relative to said first bevel surface to define a first cutting edge between said second reverse bevel surface and said first bevel surface, and a second cutting edge between said third reverse bevel surface and said first bevel surface, where a length of said first cutting edge between said second reverse bevel surface and said first bevel surface and a length of said second cutting edge between said third reverse bevel surface and said first bevel surface is
