Description
本発明は、全体的に、切除を実施するためのシステムおよび方法に関する。より具体的には、本発明は、例えば、以前に形成された組織腔において、バルーンを使用して切除を実施するためのシステムおよび方法に関する。
装置は、カテーテル、伝導性要素およびバルーンを備える。このカテーテルは管腔を有する。伝導性要素は、カテーテルに沿って配置される。バルーンは、そのカテーテルの管腔と流体連絡した内部を有する。このバルーンは、その伝導性要素と電導性に繋がれた伝導性物質から形成される。バルーンは、折り畳まれた構成および膨張した構成を有する。
一旦腫瘍が除去されたら、組織腔が残存する。この腔を囲む組織は、患者において、腫瘍の再発が最も高い可能性で生じ得る位置である。従って、腫瘍が除去された後、周囲の組織(本明細書中で、「マージン組織」とも言われる)を破壊することが望ましい。本明細書中に記載される種々の実施形態は、バルーンカテーテルデバイスに関し、そして例えば、腫瘍除去により形成される組織腔と関係するマージン組織を切除するための方法に関する。
本発明の種々の実施形態が上記に説明されているが、これらは例示のみの目的のために提示されており、そして限定のためではないことが理解されるべきである。従って、本発明の広がりおよび範囲は、上記の実施形態にいずれによっても限定されるべきでなく、添付の特許請求の範囲およびそれらの等価物に従ってのみ規定されるべきである。
