Abstract
A heart valve implant is disclosed herein. The heart valve implant comprises an inflatable valve body, a shaft, an anchor assembly and an inflation (injection) port. Also disclosed herein, are methods of trans-apically and trans-septally delivering a heart valve implant within a heart such that the valve body can be inflated in situ to partially or completely restrict blood flow through a heart valve in a closed position. The inflation (injection) port permits inflation of the valve body with an adjustable amount of an inflation fluid to attain a desired degree of inflation of the valve body when disposed within the heart valve.
Claims27
A heart valve implant comprising:
- an inflatable valve body defining a cavity comprising a proximal end and a distal end;
- a shaft extending through the proximal end of the inflatable valve body, said shaft comprising a lumen in fluid communication with said cavity;
- an anchor assembly attached to the shaft, proximal to the inflatable valve body;
- and
- an inflation port comprising one or more lumens in fluid communication with the shaft lumen.
A method of trans-apically delivering a heart valve implant within a heart, the implant comprising an inflatable valve body, a shaft, an anchor assembly, and an inflation port, the method comprising:
- trans-apically advancing an introducer comprising a lumen through an incision in an apex of a heart into a left ventricle;
- advancing said introducer through a mitral valve into a left atrium;
- advancing the heart valve implant through the introducer lumen into the left atrium, wherein said shaft of the heart valve implant extends from the inflatable valve body to beyond the incision in the apex;
- and
- removing the introducer from said heart, thereby delivering the inflatable valve body and at least a portion of the shaft within the heart.
A method of trans-apically delivering a heart valve implant within a heart, the implant comprising an inflatable valve body, a shaft, an anchor assembly, and an inflation port, the method comprising:
- trans-apically advancing an introducer comprising a lumen through an incision in an apex of a heart into a left ventricle;
- advancing the heart valve implant through the introducer lumen into the left ventricle, wherein the inflatable valve body extends from the introducer;
- partially inflating the inflatable valve body;
- advancing said introducer and partially inflated inflatable valve body through a mitral valve into a left atrium;
- advancing the heart valve implant through the introducer lumen into the left atrium;
- and
- removing the introducer from said heart, thereby delivering the inflatable valve body and at least a portion of the shaft within the heart.
