Commissure attachement featur having multiple bodies

Abstract

A prosthetic heart valve includes a collapsible and expandable stent extending in a longitudinal direction between an inflow end and an outflow end, the stent including a plurality of struts defining a plurality of cells, and a plurality of commissure attachment features disposed on the stent, each commissure attachment feature having a first end, a second end opposite the first end, and at least two bodies connected via one or more suspension struts, each of the at least two bodies having at least one eyelet.

1 . A prosthetic heart valve, comprising:
 a collapsible and expandable stent extending in a longitudinal direction between an inflow end and an outflow end, the stent including a plurality of struts defining a plurality of cells; and   a plurality of commissure attachment features disposed on the stent, each commissure attachment feature having a first end, a second end opposite the first end, and at least two bodies connected via one or more suspension struts, each of the at least two bodies having at least one eyelet.   
     
     
         2 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies are of a same shape. 
     
     
         3 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies are of a same size. 
     
     
         4 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies are of different shapes. 
     
     
         5 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies are of different sizes. 
     
     
         6 . The prosthetic heart valve of  claim 1 , wherein one or more of the at least two bodies is dome-shaped. 
     
     
         7 . The prosthetic heart valve of  claim 1 , wherein each of the at least two bodies includes multiple eyelets. 
     
     
         8 . The prosthetic heart valve of  claim 7 , wherein the multiple eyelets are arranged in a single column. 
     
     
         9 . The prosthetic heart valve of  claim 1 , wherein the one or more suspension struts includes a single suspension strut. 
     
     
         10 . The prosthetic heart valve of  claim 1 , wherein the one or more suspension struts includes multiple suspension struts. 
     
     
         11 . The prosthetic heart valve of  claim 10 , wherein the multiple suspension struts form a diamond shape. 
     
     
         12 . The prosthetic heart valve of  claim 1 , wherein the one or more suspension struts are serpentine. 
     
     
         13 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies includes three bodies. 
     
     
         14 . The prosthetic heart valve of  claim 1 , wherein the at least two bodies are aligned with one another in the longitudinal direction. 
     
     
         15 . The prosthetic heart valve of  claim 1 , wherein, when the stent is in an expanded condition, the inflow end of the stent has a first diameter and the outflow end of the stent has a second diameter greater than the first diameter. 
     
     
         16 . The prosthetic heart valve of  claim 15 , wherein a portion of the stent nearer the inflow end is cylindrical when the stent is in the expanded condition. 
     
     
         17 . The prosthetic heart valve of  claim 16 , wherein each commissure attachment feature is disposed at least partially on the cylindrical portion of the stent. 
     
     
         18 . The prosthetic heart valve of  claim 1 , wherein the stent is cylindrical when in a collapsed condition.
