- 患者の腹壁と内臓壁とに形成された瘻孔における前記腹壁の表面側に設置される体外固定部と、
前記体外固定部に連結され先端側部分が前記瘻孔から内臓内にかけて延びるようにして設置される管状体からなり、内部に主腔が形成され周壁部内に副腔が形成された供給チューブと、
前記供給チューブの先端側外周に設けられ前記副腔を介して粒状物質と液体との混合液が送り込まれることにより前記内臓内で膨張する体内固定部と
を備えた瘻孔カテーテルにおいて、
前記体内固定部を、それぞれ前記供給チューブの周面に設けられた注入口を介して前記副腔と連通する内側バルーンと前記内側バルーンの外周側に設けられた外側バルーンとで構成して、膨張時の前記内側バルーンと前記外側バルーンとの間に空間が形成されるようにし、
前記副腔と前記外側バルーンとを連通する注入口に、前記混合液中の液体は通すが粒状物質は通さないフィルタを設け、前記副腔から前記内側バルーンに連通する注入口を介して前記内側バルーンに前記混合液を充填できるとともに、前記副腔から前記外側バルーンに連通する注入口および前記フィルタを介して前記外側バルーンに前記混合液中の液体を充填できるようにしたことを特徴とする瘻孔カテーテル。 - 前記内側バルーンを伸縮性の小さな材料で構成し、前記外側バルーンを前記内側バルーンよりも伸縮性の大きな材料で構成した請求項1に記載の瘻孔カテーテル。
- 前記内側バルーンが膨張したときの大きさが一定になるようにした請求項1または2に記載の瘻孔カテーテル。
- 前記内側バルーンと、前記外側バルーンとをそれぞれ接着により前記供給チューブに固定し、前記供給チューブに対する前記内側バルーンの接着部と前記外側バルーンの接着部との前記供給チューブが延びる方向に沿った位置をずらした請求項1ないし3のうちのいずれか一つに記載の瘻孔カテーテル。
- 前記粒状物質を硫酸バリウムで構成した請求項1ないし4のうちのいずれか一つに記載の瘻孔カテーテル。
