摘要： An apparatus and method for automatically retroperfusing a coronary vein. The apparatus includes an intraluminal graft having a tubular body extending between a proximal end and a distal end. The proximal end is for fluidly connecting to an artery to automatically supply retrograde blood for retroperfusion. The tubular body and the distal end are extendable into a vein that is fluidly connected with the coronary vein to be retroperfused. The distal end includes an expandable stent for securing the distal end in the coronary vein.

摘要： A stentless bioprosthetic valve includes at least one piece of biocompatible material comprising a bi-leaflet conduit. The conduit has a distal end, a proximal end defining a first annulus for suturing to the valve annulus of a heart, and leaflets extending between the proximal and distal ends. The distal end defines a second annulus having a profile substantially similar to a first annulus profile, at which the leaflets terminate. The second annulus is sutured to free edges of the leaflets of the native mitral valve that remain intact following resection of the native mitral valve. Therefore, the native chordae tendineae continue to provide prolapse prevention and left ventricular muscle support functions in addition to maintaining continuity between the valve annulus and the papillary muscles. The second annulus is spaced from the papillary muscles. A method for replacing the native mitral valve with a stentless bioprosthetic valve is also provided.
摘要翻译： 无支架生物假肢瓣膜包括至少一片包含双叶导管的生物相容性材料。 导管具有远端，限定用于缝合到心脏的瓣膜环的第一环的近端，以及在近端和远端之间延伸的小叶。 远端限定具有基本上类似于第一环形轮廓的轮廓的第二环形，叶片终止于该第一环状轮廓。 将第二个环缝合到自然二尖瓣的小叶的自由边缘，在切除天然二尖瓣后保持完整。 因此，除了保持瓣膜环和乳头肌之间的连续性之外，天然腱索腱还继续提供脱垂预防和左心室肌支撑功能。 第二个环与乳头肌间隔开。 还提供了用无支架生物假体瓣膜替代原生二尖瓣的方法。

摘要： An apparatus for automatically retroperfusing a coronary vein includes an intraluminal cannula having a main body portion extending between a proximal end portion and a distal end portion. The proximal end portion is for connecting to an artery outside of the pericardium to automatically supply oxygenated blood from the artery for retroperfusion. The main body portion and the distal end portion are insertable through a vein that is fluidly connected with the coronary vein and into the coronary vein. An expandable stent is attached to the distal end portion for expanding radially into engagement with the interior wall of the coronary vein to secure the distal end portion at a desired location within the coronary vein. Occluding structure for at least partially occluding the coronary vein is provided at the distal end to decrease the back-flow of blood into the right atrium during retroperfusion. The cannula includes passages that allow a limited amount of blood to bypass the occluding structure.
