Abstract
【解決手段】インプラント組立体14は、細長いプッシャ部材18と、プッシャ部材18の遠位端部に取付けられたインプラント可能器具(血管閉塞器具)22と、プッシャ部材18に設けられ且つ電解式に切離し可能なジョイント20を有する。切離し可能なジョイント20を切離すと、インプラント可能器具22がプッシャ部材18から分離する。インプラント組立体14は、更に、プッシャ部材18の遠位端部によって支持されたコイル等の戻り電極を有し、戻り電極は、切離し可能なジョイント20に近接しているが、それから電気的に絶縁され、更にインプラント組立体14が、切離し可能なジョイント20と電気的連通関係をなしてプッシャ部材18の近位端部によって支持された端子を有する構成とする。
