- 請求項1〜3のいずれか一項による器具にして、帯(12)が外管(7)の放射方向の膨張によって包被体(3)の方へ押し付けられることを特徴とする器具。
- 請求項1〜4のいずれか一項による器具にして、包被体(3)が可変的に膨張可能ではあるがねじりに強く形成されていることを特徴とする器具。
- 請求項5による器具にして、包被体(3)が網(16)乃至織物乃至少なくとも二つの逆方向に走る螺旋を持っていることを特徴とする器具。
- 請求項1〜6のいずれか一項による器具にして、内部体(2)が少なくともその内管(6)の内壁(8)に、乃至は、包被体(3)が少なくともその外側(17)に、親水性の膜(18)を持っていることを特徴とする器具。
- 請求項1〜7のいずれか一項による器具にして、内部体(2)が細線乃至円周側で網状の物(19)によって硬直化されていることを特徴とする器具。
- 請求項8による器具にして、細線乃至網状の物(19)が鋼又はチタンとニッケルの合金によって製作されていることを特徴とする器具。
- 請求項1〜9のいずれか一項による器具にして、器具(1)の外径(20)がその先端に向かってしだいに細くなっていることを特徴とする器具。
