Patent Images
1. A heart valve implant comprising:
- a guide shaft comprising a distal end and a proximal end;
an anchor coupled to said guide shaft proximate said distal end;
a valve connector connected to said guide shaft;
a framework connected to valve connector and extending radially outwardly from said valve connector;
said framework comprising a first portion extending radially outwardly from said valve connector and a second portion extending further radially outwardly from said first portion of said framework;
a valve portion connected to said framework and disposed proximate to and distally of said first portion of said framework, at least a portion of said valve portion is movable away from said framework during diastole and into contact with said framework during systole; and
an apron connected to said framework and disposed proximate to and distally of said second portion of said framework, said apron comprising material which permits ingrowth of native heart tissue.
