Method of in situ formation of translumenally deployable heart valve support

Abstract

A method of implanting a prosthetic valve within the heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A first chamber of the inflatable structure is inflated and then, independently, a second chamber of the inflatable structure is inflated.

1 . A method of implanting a prosthetic valve within the heart, the method comprising:
 translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart;   inflating a first chamber of the inflatable structure; and   independently inflating a second chamber of the inflatable structure.   
     
     
         2 . The method of  claim 1 , wherein inflating a first chamber of the inflatable structure comprising inflating a distal end of the valve. 
     
     
         3 . The method of  claim 2 , further comprising proximally retracting the valve after the first chamber is at least partially inflated. 
     
     
         4 . The method of  claim 1 , wherein inflating a second chamber of the inflatable structure comprising inflating a proximal end of the valve.
