摘要： This present invention provides a surgical rivet, a rivet deployment actuator, a rivet cutting instrument and a method for securing a prosthetic valve to the heart which has the potential to substantially decrease the ischemic time required for valve implantation and allow larger prostheses to be inserted in small annuli. The surgical rivet is comprised of two flexible preformed elements capable of assuming a preconfigured shape once it is delivered and secured with the deployment actuator. The deployment actuator is a reusable instrument that lowers the prosthesis to the annulus, secures the prosthesis with an “O” ring and cuts and deploys the flexible elements so that they rest on the sewing ring of the prosthetic valve. The present invention eliminates the tedious and time-consuming tasks of tying sutures which may be particularly difficult in small annuli. It also automatically cuts the sutures to the appropriate length. The use of single rivets allows for expansion to the annulus and insertion of one full size larger (2 mm) prosthesis than what is possible using the classical horizontal pledget mattress technique. This feature is of particular importance in small annuli where prosthesis/patient mismatch can lead to suboptimal long term results. 1

摘要翻译： 本发明提供了一种手术铆钉，铆钉展开致动器，铆钉切割工具和用于将人造瓣膜固定到心脏的方法，所述方法具有显着降低瓣膜植入所需的缺血时间并允许较大的假体插入到心脏中 小环 手术铆钉由两个柔性预成形件构成，能够在部署致动器被输送并固定之后，承担预先配置的形状。 部署致动器是一种可重复使用的仪器，将假体降低到环空，用“O”形环固定假体，并切割并展开柔性元件，使其靠在人工瓣膜的缝合环上。 本发明消除了在小环境中特别困难的缝合线的麻烦和耗时的任务。 它也会自动将缝合线切割成适当的长度。 使用单个铆钉允许扩展到环形和插入一个全尺寸更大（2毫米）的假体比使用经典的水平毛绒床垫技术可能。 这个特征对于假体/患者不匹配可能导致不理想的长期结果的小环境中特别重要。 ¹
