摘要：A system for replacing a deficient native aortic valve includes an implantableprosthetic valve having a self-expandable frame and a valve assembly formed with threevalve leaflets. The self-expandable frame includes three angularly spaced longitudinal
bars of fixed length defining respective slots and a plurality of web-like constructionsextending between and connected to the longitudinal bars. The valve assembly includescommissures extending outwardly through the slots where they are supported on theoutside of the frame. Each leaflet includes an inlet end portion secured to the inside ofthe frame with stitching extending through the leaflet and around adjacent frameportions. The system also includes a restriction tube adapted for insertion into apatient's body. The prosthetic valve is capable of being crimped for insertion into therestriction tube and capable of self-expansion upon release from the restriction tube fordeployment in the deficient native aortic valve.
