Abstract
Inflatable 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 an inflatable balloon portion movably connected to an anchored guide shaft and movable from a distal position in the ventricle to a more proximal position between leaflets of a native atrioventricular valve. The range of movement of the inflatable valve body can be adjusted in situ after or before the guide shaft has been anchored to native heart tissue during surgery.
Claims24
A heart valve implant comprising:
- a guide shaft comprising a first end and a second end;
- an anchor coupled to said guide shaft proximate said first end;
- an inflatable valve body slidably connected to said guide shaft within a predetermined range of movement, said inflatable valve body comprising an outer dimension;
- at least one range limiting structure connected to said guide shaft for changing the range of movement of said inflatable valve body relative to said guide shaft, said range limiting structure comprising at least one filament connected to said guide shaft and connected to said inflatable valve body.
A heart valve implant comprising:
- a guide shaft comprising a first end and a second end;
- an anchor coupled to said guide shaft proximate said first end;
- an inflatable valve body slidably connected to said guide shaft within a predetermined range of movement, said inflatable valve body comprising an outer dimension;
- and
- a plurality of flexible filaments connected to said guide shaft which limit the range of movement of said inflatable valve body relative to said guide shaft.
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 first end and a second end;
- an anchor coupled to said shaft proximate said first end;
- an inflatable valve body slidably connected to said guide shaft within a predetermined range of movement, said valve body comprising an outer dimension;
- at least one range limiting structure connected to said guide shaft and said inflatable valve body for changing the range of movement of said valve body relative to said guide shaft, comprising at least one filament;
- positioning said heart valve implant at least partially within a heart via a transcatheter venous procedure;
- securing said anchor to native heart tissue;
- and
- adjusting the range of movement of said inflatable valve body relative to said guide shaft.
