カテーテルであって、それを通して胆嚢にフィルター装置を移行するために構成されたカテーテルと、
を含むシステム。 - 胆嚢にフィルター装置を植え込むための方法であって、
植え込みのためにフィルター装置を胆嚢に進路案内すること、但しフィルター装置は少なくとも一つの遮断部分を含む;
フィルター装置の遮断部分を胆嚢開口から胆嚢に入れること;
胆嚢中で遮断部分を手動的に又は自動的に拡張すること;
胆嚢中のいかなる胆石も胆嚢の遠位端の方へかつ胆嚢開口から離れるように押し、それによってフィルター装置の適切な及び/又は完全な拡張のために胆嚢内の空間を清掃すること;
フィルター装置のフィルター部分を胆嚢に導入すること;及び
胆嚢中のフィルター部分を手動的に又は自動的に拡張すること
を含む方法。 - 遮断部分及びフィルター部分が同じ構成要素であり、遮断及び濾別が同じ構成要素によって同時に実施される、請求項17に記載の方法。
- 遮断部分を入れた後でかつフィルター部分を導入した後に固定部分を展開することをさらに含む、請求項17に記載の方法。
