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 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;
positioning said heart valve implant at least partially within a heart via a transcatheter venous procedure; and
securing said anchor 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 guide shaft.
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 guide shaft.
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 with native heart leaflets.
7. A method according to claim 1 further comprising the step of stapling said apron to the native atrial annulus.
8. A method according to claim 1 further comprising the step of affixing said apron to the native atrial annulus.
9. A method of deploying a heart valve implant in a patient comprising the steps of:
providing 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;
positioning said heart valve implant at least partially within a heart via a transcatheter procedure; and
securing said anchor to native heart tissue.
10. A method of deploying a heart valve implant in a patient according to claim 9 further comprising the step of adjusting the position of the valve portion relative to said guide shaft.
11. A method of deploying a heart valve implant in a patient according to claim 10 wherein said adjusting step comprises changing the position of said valve portion relative to said guide shaft.
12. A method according to claim 9 further comprising the step of positioning said valve portion in contact with native heart leaflets.
13. A method according to claim 9 further comprising the step of positioning said valve portion adjacent said native heart leaflets.
14. A method according to claim 9 further comprising the step of positioning said valve portion within with native heart leaflets.
15. A method according to claim 9 further comprising the step of affixing said apron to the native atrial annulus.
16. A method according to claim 15 further comprising the step of stapling said apron to the native atrial annulus.
