Heart Valve Stent

Abstract

A heart valve stent ( 10 ) having a section equipped to receive a heart valve implant ( 30 ) and several proximally disposed anchoring elements ( 20 ), characterized by several anchoring threads ( 40 ), which with the one end thereof is fastened to the stent ( 10 ), and also with a brace ( 80 ) fastening the anchoring threads ( 40 ) with the other end thereof to the distal chamber wall to provide tension between the heart chamber wall and the proximally anchored anchoring elements ( 20 ).

1 . A heart valve stent comprising:
 a body section equipped to receive a heart valve implant;   a plurality of proximally disposed anchoring elements;   a plurality of anchoring threads, each having a first end portion attached to the stent, and a second end portion; and   a thrust bearing for securing the second end portions of the plurality of anchoring threads to a distal heart chamber wall to provide tension between the distal heart chamber wall and the proximally disposed anchoring elements, wherein the heart valve stent is formed as a truncated cone.   
     
     
         2 . The heart valve stent according to  claim 1 , wherein the plurality of anchoring threads are affixed to an end portion of the body section that opposes the plurality of anchoring elements. 
     
     
         3 . The heart valve stent according to  claim 1 , further comprising at least one suture-length regulatory element for adjusting a length of at least one of the plurality of anchoring threads. 
     
     
         4 . The heart valve stent according to  claim 1 , wherein the thrust bearing constitutes a suture-length regulatory element. 
     
     
         5 . The heart valve stent according to  claim 1 , further comprising a heart valve implant received in the body section. 
     
     
         6 . The heart valve stent according to  claim 11 , wherein, in a plane of the mitral valve, an annulus of the heart valve stent is substantially oval or u-shaped. 
     
     
         7 . (canceled) 
     
     
         8 . The heart valve stent according to  claim 5 , further comprising a sealing membrane adapted to be arranged between the heart valve implant and the stent. 
     
     
         9 . The heart valve stent according to  claim 5 , further comprising a sealing membrane arranged between the plurality of anchoring elements and the heart valve implant. 
     
     
         10 . The heart valve stent according to  claim 1 , wherein at least one of the plurality of anchoring elements is made from a shape memory alloy. 
     
     
         11 . The heart valve stent according to  claim 5 , wherein the heart valve implant constitutes a mitral valve.
