摘要： A prosthetic heart valve comprising a stent having an annular base and a plurality of legs extending upwardly from said base; a valve element circumscribing said stent and attached thereto, said valving element comprising a number of cooperating valve leaflets equal to the number of said legs; and a layer of biologically-compatible material secured to said stent and positioned between said stent and said leaflets, said layer having a smooth, non-abrasive outer surface and covering all of the surfaces of said stent that, in the absence of said layer, would contact the mobile portions of said leaflets during the normal function of the valve.

摘要： Novel tubular prostheses, e.g. vascular or ureteral prostheses, prepared by sewing the opposed edges of a sheet of pericardial tissue together with a thread to form a longitudinal seam are disclosed. By disposing the thread in a suitable configuration along the seam, for example in a plurality of stitches each of which is secured with a knot, a tubular prosthesis results that can be cut transversely between its ends without unravelling the thread and substantially damaging the same. Use of bovine pericardial tissue is preferred since the range of compliances of tubular prostheses made therefrom is approximately comparable to the range in human arteries and veins, whereas tubular prostheses made from porcine pericardial tissue tend to be too compliant.

摘要翻译： 新型管状假体，例如 公开了通过将一张心包组织的相对边缘与线一起缝合以形成纵向缝合而制备的血管或输尿管假体。 通过沿着接缝将线设置在合适的构造中，例如以多个针脚固定，其中每一个都用结固定，导致可以在其端部之间横向地切割的管状假体，而不会松开线并且基本上损坏线。 牛心包膜的使用是优选的，因为由其制成的管状假体的一致性范围大致与人动脉和静脉的范围相当，而由猪心包组织制成的管状假体倾向于太柔顺。
