Claims (11)

  1. 体内の血管内から医療装置を回収する際に使用するための医療用カテーテルであって、
    内面および外面を備えた壁を有し、壁が先端部と基端部とを有し、内面により管腔が区画され、外面は先端部に向かって内側に先細りしていることを特徴とする先端チップ部材を備え、
    管腔の先端部の径は医療装置の径よりも小さく、壁の形状は、医療装置を管腔内に回収する前は歪んでいないが、医療装置を管腔内に回収する際には歪みを生じて先端部が内側に巻き込まれた状態になる
    ことを特徴とするカテーテル。
  2. 前記チップ部材が先端に向かって径方向に内側に先細る、請求項１に記載のカテーテル。
  3. さらにカテーテル本体部を備え、前記チップ部材がカテーテル本体部の先端部に取り付けられた、請求項２に記載のカテーテル。
  4. 前記カテーテル本体部は人体の管腔内に配置される大きさである、請求項３に記載のカテーテル。
  5. 前記カテーテル本体部は血管内に配置される大きさである、請求項３に記載のカテーテル。
  6. 前記カテーテル本体部はガイドワイヤが通る大きさの管腔を有する、請求項５に記載のカテーテル。
  7. 前記医療装置は塞栓防御装置である、請求項１に記載のカテーテル。
  8. 前記壁は先端部に前記チップ部材の管腔の軸に向かって内側に湾曲した部分を有し、前記チップ部材は、装置を回収すると管腔の径が拡大して医療装置の径に適合するようにコンプライアンスの高い材質で形成される、請求項１に記載のカテーテル。
  9. さらにカテーテル本体部を備え、前記チップ部材がカテーテル本体部の先端部に取り付けられた、請求項８に記載のカテーテル。
  10. 前記カテーテル本体部は血管内を進められる大きさである、請求項９に記載のカテーテル。
  11. 前記カテーテル本体部は管腔を有し、管腔を通って延びるガイドワイヤ上を進められる大きさである、請求項１０に記載のカテーテル。
