Implantable transcatheter intracardiac devices and methods for treating incompetent atrioventricular valves
View Patent ↗Heart valve implants and methods utilizing those valves designed to reduce or eliminate the regurgitant jet associated with an incompetent atrioventricular valve. The heart valve implants, which are deployed via a transcatheter venous approach, comprise a collapsible framework connected to an anchored guide shaft, a valve portion and an apron which permits ingrowth of native heart tissue into the apron.
1. A method of deploying a heart valve implant in a patient comprising the steps of:
providing a heart valve implant comprising:
a valve connector;
a framework connected to said 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 flexible 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 to allow blood flow during diastole and into contact with said framework to impede blood flow during systole;
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; and
a cardiac anchor connected to said valve connector;
positioning said heart valve implant at least partially within a heart via a transcatheter venous procedure; and
securing said heart valve implant within a heart with said cardiac anchor secured to native heart tissue.
2. A method of deploying a heart valve implant in a patient according to claim 1 further comprising the step of adjusting the position of the valve portion relative to said anchor.
3. A method of deploying a heart valve implant in a patient according to claim 2 wherein said adjusting step comprises changing the position of said valve portion relative to said anchor.
4. A method according to claim 1 further comprising the step of positioning said valve portion in contact with native heart leaflets.
5. A method according to claim 1 further comprising the step of positioning said valve portion adjacent said native heart leaflets.
6. A method according to claim 1 further comprising the step of positioning said valve portion within native heart leaflets.
7. A method according to claim 1 further comprising the step of attaching said apron to the native atrial annulus.
