1. A mitral valve implant comprising:
- an inflatable valve body defining a cavity;
a shaft extending from the inflatable valve body to a terminal end, said shaft comprising a lumen in fluid communication with said cavity; and
an anchor assembly coupled to the shaft between the inflatable valve body and an inflation port, said anchor assembly comprising a passageway, a compression fitting, and an anchor support, said anchor support comprising one or more arms extending outwardly from the passageway, wherein each of the one or more arms extends less than 360°
around the passageway;
wherein the inflation port is coupled to the terminal end of the shaft, and the inflation port comprising one or more lumens in fluid communication with the shaft lumen; and
wherein the inflatable valve body in an inflated state is sized 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.

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.
