Abstract
Description
一実施態様において、前記可撓性部材と前記ブッシングとは、当該可撓性部材を電流から保護するために非導電性要素によって相互に離間されていてもよい。
一実施態様において、前記カプセルは、絶縁されているか、又は非導電性材料から形成されているか、のいずれか一方であってもよい。
一実施態様において、前記制御部材の一部分は、前記装置の近位部を保護するために絶縁されていてもよい。
一実施態様において、前記コア部材の前記近位部は、前記クリップ・アームの近位端部を嵌合するための拘束タブを含んでいてもよく、前記遠位部は、前記クリップ・アームのそれぞれを経由して横方向に延びる対応の切欠を嵌合させるための整合突出部を含んでいる。前記コア部材の前記遠位部は、解放可能に連結する何らかの手段を介して前記クリップ・アームに連結されていてもよく、解放可能に連結する何らかの手段は、たとえば、前記クリップ・アーム若しくは前記コア部材のいずれかの変形可能な部分、又は、前記クリップ・アーム若しくは前記コア部材のうちの1つに固定して連結される中間要素であり、そのそれぞれは、予め設定された荷重を受けた場合に、コア部材及びクリップ・アームの関係を断つように構成され得る。
また、本発明は、近位部と遠位部とを備えたクリッピング装置に関する。前記近位部は、近位端部から遠位端部へ長手方向に延びる可撓性部材と、前記可撓性部材の遠位端部に連結されたブッシングとを含む。前記遠位部は、当該遠位部が近位部から配置可能になるように前記近位部に解放可能に連結されており、前記遠位部は、ブッシングに解放可能に連結されたカプセルを含んでおり、前記カプセルは、近位端部から遠位端部へ長手方向に延びるとともに全長にわたって延びるチャネルを含んでおり、近位端部から延びるクリップ・アームが前記カプセルの前記チャネルの中に摺動可能に受け入れられる。前記クリップ・アームは、当該クリップ・アームの遠位端部が前記カプセルの遠位端部を越えて遠位側に延びて相互に離間する開配置と、当該クリップ・アームが前記カプセルの内面によって拘束され、前記クリップ・アームの遠位端部が相互に引き寄せられる閉配置との間で移動可能である。前記クリップ・アームの前記近位端部には、コア部材が連結されており、前記コア部材は、予め設定された荷重を受けた場合に、機能しなくなるように設計された破壊可能なリンクによって相互に連結された近位部と遠位部とを含む。前記コア部材には、近位端部が電流を前記クリップ・アームに供給するために電源に接続された導電性の制御ワイヤが連結される。
一実施態様において、前記クリップ・アームの前記遠位端部は、相互に向かって横方向に延びる鋭利な歯を含む。
また、本発明は、目標組織を治療するための方法であって、本方法は、カプセルと、遠位端部が相互に離間する開配置と遠位端部が相互に引き寄せ合う閉配置との間で移動可能に前記カプセルの中に摺動可能に収容されるクリップ・アームとを含み、クリッピング装置の近位部に解放可能に連結されるとともに当該近位部から配置可能な前記クリッピング装置の遠位部を、生体の中の目標領域まで挿入する工程と、前記クリップ・アームを目標組織に接触させて位置決めする工程と、目標組織を治療するために、カプセル及びクリップ・アームのうちの1つに接続された導電性部材を介して電気的なエネルギーをクリップ・アームに供給する工程と、を備える方法に関する。
