A prosthetic device for a heart valve having a valve portion selectively expandable from a folded shape for implantation to an expanded operating configuration and provided with an artificial valve leaflet capable of reproducing a leaflet function of a natural heart valve. The prosthesis also comprises a constraint which surrounds the valve portion and restrains expansion in the actuated expanded configuration. The prosthesis also includes a connection for stably connecting the valve portion to the constraint via a connecting member. The present invention allows both the use of minimally invasive surgical transplantation and the use of transplantation based entirely on transcatheter surgery.(FIG.移植用に畳まれた形状から作動拡張形状へと選択的に拡張可能で、自然心弁の弁尖機能を再現可能な人工弁尖が設けられた弁部を備える心弁用人工器官。前記人工器官はまた、前記弁部を取り囲んで拡張を前記作動拡張形状に束縛する束縛部を備える。前記人工器官はまた、接続部材を介して前記弁部を前記束縛部へと安定的に接続する接続部を備える。本発明により低侵襲性外科移植術の使用および経カテーテル術に完全に基づく移植術の使用の両方が可能になる。【選択図】図1
