Description
本出願は、米国特許出願番号第08/642,756号(1996年5月3日出願)の一部継続出願である。米国特許第5,160,336号もまた、本明細書中に参考として援用される。
本発明は、身体から物質を取り除くための回収デバイスに関する。
生物学的物質(例えば、結石)は、少なくとも、腎臓、尿管、または胆管に残留し得る。結石は、非常に有痛性であり得、そして医療処置を必要とし得る。身体からの結石の除去は、過去に、2つの方法によって達成されている。第1の方法は、従来の外科手術を通じての結石除去である;自明の欠点、危険および弱点を伴う処置である。第2の方法は、内視鏡の誘導の下で結石を除去することである。この方法では、握りデバイスが、身体腔を通じて結石の位置まで誘導され、そして内視鏡の誘導の下で使用して、その結石を握って除去する。結石の除去のために過去に使用された握りデバイスは、バスケットの中心から外向きに湾曲する一般的にまっすぐな脚を有するバスケットデバイスを備える。
本発明は、身体からの物質の回収のためのデバイスおよび方法を提供する。より詳細には、本発明は、身体中の結石をデバイスのバスケットに固定して、結石を効果的に断片化し得、次いで結石および/またはその断片をバスケットを介して除去するためのデバイスおよび方法に関し、このバスケットは、本発明に従って形成され、可撓性でありかつ互いに比較的密接に間隔をあけられた(例えば、約2mm以下の間隔)、複数の、らせん形状の略平行の重複せず交差しない脚を有する。
上記に加えて、本発明は、以下を提供する:
(項目1) 身体から物質を回収するためのデバイスであって、以下:
シースを通じて伸長する管腔および遠位端を備えるシース;および
バスケットであって、該バスケットは、該バスケットが該シースの該管腔内に引き込まれている収縮位置から、該バスケットが該シースの該遠位端を越えて伸長して開く拡張位置へと該シースに対して移動可能であり、該バスケットは、第1部および第2部を備え、該2つ以上の脚は、該第1部から該第2部に伸長し、該バスケットはさらに、該第1部と該第2部との間に位置する中間部を備え、ここでこれらの脚は、らせん状に配置されて実質的に平行かつ交差せず、該バスケットの該中間部は、該バスケットが拡張位置にある場合に、該第1部および該第2部に対して半径方向に外向きに変位される、バスケット、
を備える、デバイス。
(項目2) 身体から物質を回収するためのデバイスであって、以下:
シースを通じて伸長する管腔および遠位端を備えるシース;および
バスケットであって、該バスケットは、該バスケットが該シースの該管腔内に引き込まれている収縮位置から、該バスケットが該シースの該遠位端を越えて伸長して開く拡張位置へと該シースに対して移動可能であり、該バスケットは、第1部および第2部を備え、該2つ以上の脚は、該第1部から該第2部に伸長し、該バスケットはさらに、該第1部と該第2部との間に位置する中間部を備え、ここでこれらの脚は、らせん状に配置されて実質的に平行かつ交差せず、該バスケットの該中間部は、該バスケットが拡張位置にある場合に、該第1部および該第2部に対して半径方向に外向きに変位される、バスケット、
それにより、該拡張位置のバスケットは、該物質が断片化され、該断片化された物質が、該バスケットの中に入りかつ該バスケットによって捕捉される。
(項目3) 前記中間部における前記脚の各々が、隣接する脚から0.0787インチ〜0.394インチの間隔をあけられる、項目1に記載のデバイス。
(項目4) 前記シースの前記管腔に伸長し、該バスケットに操作可能に装着され、その結果該細長部材の相対的移動が、該拡張位置と該収縮位置との間のバスケット移行を生じる細長部材、
を備える、デバイス。
(項目5) 身体から物質を取り除くための方法であって、以下の工程:
身体腔に、シースおよびバスケットを備えるデバイスを挿入する工程であって、該バスケットは、該バスケットが該シース内に引き込まれている収縮位置から、該バスケットが該シースの該遠位端を越えて伸長して開く拡張位置へと該シースに対して移動可能であり、該バスケットは、第1部および第2部を備え、該2つ以上の脚は、該第1部から該第2部に伸長し、該バスケットはさらに、該第1部と該第2部との間に位置する中間部を備え、ここでこれらの脚は、らせん状に配置されて実質的に平行かつ交差せず、該バスケットの該中間部は、該バスケットが拡張位置にある場合に、該第1部および該第2部に対して半径方向に外向きに変位される、工程、ならびに
該収縮位置から該拡張位置まで該バスケットを移動し、それにより該物質をブロックすることによって、該身体腔に該物質を固定化する工程;
該身体腔において該物質を断片化し、そして該拡張したバスケットを使用して、断片化の間の該物質の動きを制限する工程;
該バスケット内で少なくともいくらかの該断片化した物質を捕捉する工程;および
該バスケット内の少なくともいくらかの該断片化した物質を、該身体腔からの該捕捉した断片化した物質とともに該デバイスを引くことによって回収する工程、
を包含する、方法。
図1は、本発明に従う拡張可能デバイス10を図示する。図1に示される実施態様において、拡張可能デバイス10は、シースまたはカテーテル12、カニューレ14およびメッシュ部16を備える。カレーテル12は、好ましくは、その近位端で、ハンドル18を有する。カニューレ14はまた、その近位端で、ハンドル20を備える。
