Description
本発明はカニューレ・アセンブリに係り、特に血液輸送、好ましくは、患者の心臓あるいは循環器系と、埋込型の血液ポンプ機器との間の血液輸送に適したカニューレ・アセンブリに係るものである。
血液ポンプは、通常、うっ血性心不全および患者の循環器系に関わるその他の疾患を治療するために使用される。血液ポンプは、一般的に、カニューレを介して、心臓および循環器系に接続される必要がある。
血栓形成部位となるからである。
本発明の1つの広義の形態のカニューレは、以下のような血液輸送用カニューレである。すなわち、該カニューレは、第一端部と第二端部との間の血液経路を定める、細長く柔軟性を有するチューブ状の軸部を備え、上記軸部は、上記軸部が実質的に損傷することなく、上記血液経路を閉塞するように固定されるようになっているとともに、ねじれ応力に対して抵抗性を有するものである。
本発明に係る第一の好適な実施形態は、左心室と血液ポンプとをつなぐ、脱血カニューレ(inflow cannula)である。下記にこの実施形態について、複数の図を参照して説明する。
中空穴21内に固定されている。
Claims (4)
- 血液経路を定める、細長く柔軟性を有するチューブ状の軸部を備え、
上記軸部は、弾力性を有する漏斗形のアダプタを含んでおり、
上記アダプタは、心臓へ少なくとも部分的に挿入可能に取り付けられるものであり、アダプタの内側に凸面を有しており、上記軸部の挿入側の先端に設けられ、心臓へ挿入される、血液輸送用カニューレの先端に向けて末広に形成されるものであり、
上記軸部が実質的に損傷することなく、上記血液経路を閉塞するようにクランプで締められるようになっているとともに、ねじれ応力に対して抵抗性を有するものである血液輸送用カニューレ。 - 上記柔軟性を有するチューブ状の軸部の外側部は、50〜65ショアの硬度を有するものである請求項1に記載のカニューレ。
- 上記チューブ状の軸部の外側部が外層であり、
上記柔軟性を有するチューブ状の軸部は、さらに、上記外層よりも実質的に硬度が低い内層を有する請求項1に記載のカニューレ。 - 上記内層は、約35ショアの硬度を有するものである請求項3に記載のカニューレ。
