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.

1-27. (canceled)
A mitral valve implant comprising:
- an inflatable valve body defining a cavity;
- a shaft extending from the inflatable valve body, said shaft comprising a lumen in fluid communication with said cavity;
- an anchor assembly attached to the shaft;
- and
- an inflation port comprising one or more lumens in fluid communication with the shaft lumen;
- wherein the inflatable valve body is configured for at least partial placement in a mitral valve so as to at least partially restrict a flow of blood through the mitral valve in a closed position of the mitral valve.
A mitral valve implant comprising:
- an inflatable valve body defining a cavity;
- a shaft extending from the inflatable valve body, said shaft comprising a lumen and coupled to the inflatable valve body;
- an inflation port configured to be coupled to the shaft and to be secured subdermally;
- wherein the inflation port, the lumen of the shaft and the cavity of the inflatable valve body are in fluid communication.
A method of delivering a mitral valve implant comprising an inflatable valve body and a shaft, the method comprising:
- creating an incision at or near an apex of a heart into a left ventricle;
- advancing an introducer comprising a lumen through the incision at least into the left ventricle;
- introducing the inflatable valve body and at least a portion of the shaft in the introducer lumen;
- wherein the shaft of the mitral valve implant extends from the inflatable valve body to beyond the incision at or near the apex;
- advancing the mitral valve implant through the introducer so that a portion of the inflatable valve body protrudes from the introducer;
- partially inflating the inflatable valve body with an inflation fluid;
- atraumatically advancing the portion of the inflatable valve body of the mitral valve implant through a mitral valve and at least partially into a 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.
A method of trans-apically delivering a mitral valve implant within a heart, the implant comprising an inflatable valve body and a shaft, the method comprising:
- advancing an introducer comprising a lumen through an incision in a heart into a left ventricle;
- advancing a portion of the inflatable valve body of the mitral valve implant through the introducer lumen into the left ventricle and at least partially 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.
