Description
本出願は、米国仮特許出願第60/814,309号(2006年6月15日出願)の利益を主張する。
本発明は、血管動脈瘤の塞栓形成のような体腔の閉塞のためのデバイス、ならびに、かかるデバイスの作製方法および使用方法に関する。
結果は、第1世代ヒドロゲル1(HES)、第2世代マクロマー含有ヒドロゲル2、酸処理された第2世代マクロマー含有ヒドロゲル2、およびマイクロコイルの間の、相対的剛性の大きな差異を示している。ヒドロゲル1は白金マイクロコイル(大)の20倍近い剛性を有し、しかるに、ヒドロゲル2は白金マイクロコイル(大)の5倍未満の剛性を有する。酸処理されたヒドロゲル2は、白金マイクロコイル(大)よりも低い剛性を有し、白金マイクロコイル(小)とほぼ同程度の剛性を有する。当業者は、本発明で開示された方法および物質によって、はるかに柔軟性のある非膨張時クロマー含有ヒドロゲルが提供されることを認識する。医療デバイスにおいて使用されるときには、これらのヒドロゲルは、同様により柔軟性のある医療デバイスをもたらし得る。
また、本発明は以下のとおりであってもよい。
(1)動物内での移植のためのデバイスであって、該デバイスは、イオン化官能基を有するヒドロゲルを備え、該ヒドロゲルは、ポリ(エチレングリコール)ジアクリルアミド、ポリ(エチレングリコール)ジアクリレート、ポリ(エチレングリコール)ジメタクリレート、またはそれらの組み合わせ、の少なくとも1つのマクロマーを備え;そして当該少なくとも1つのマクロマーは約400グラム/モルから約35,000グラム/モルまでの分子量を有し、さらに、該ヒドロゲルは環境応答性であり、さらに、該ヒドロゲルは測定羽根に釣り合い重りを取り付けた試料剛性試験機を使用して測定した場合に約0.1 mgから約85 mgまでの非膨張時の曲げ抵抗を有する、前記デバイス。
(2)前記ヒドロゲルは、ポリエーテル、ポリウレタン、またはそれらの組み合わせを備える、(1)に記載のデバイス。
(3)前記イオン化官能基は、塩基性基を備える、(1)に記載のデバイス。
(4)前記塩基性基は、アミン、またはそれらの組み合わせを備える、(3)に記載のデバイス。
(5)前記塩基性官能基は、前記官能基のpKaを上回るpHで脱プロトン化され、または該官能基のpKa未満のpHでプロトン化され得る、(4)に記載のデバイス。
(6)前記イオン化官能基は、酸性基を備える、(1)に記載のデバイス。
(7)前記酸性基は、カルボン酸、またはそれらの組み合わせを備える、(6)に記載のデバイス。
(8)前記酸性官能基は、前記官能基のpKa未満のpHでプロトン化され、または該官能基のpKaを上回るpHで脱プロトン化され得る、(7)に記載のデバイス。
