Abstract
A trans-apical implant includes a spacer defining spacer cavity configured to be expanded from a retracted position, a shaft extending from the spacer, the shaft defining an inflation lumen fluidly coupled to the spacer cavity and configured to be fluidly coupled to an expansion medium source, and a spacer valve assembly disposed within at least one of the spacer or shaft, the spacer valve assembly configured to allow selectively allow an expansion medium to flow into the spacer cavity to be selectively expand the spacer from a retracted position to an expanded position.
Claims20
An implant comprising:
- a spacer defining spacer cavity configured to be expanded from a retracted position;
- a shaft extending from said spacer, said shaft defining an inflation lumen fluidly coupled to said spacer cavity and configured to be fluidly coupled to an expansion medium source;
- and
- a spacer valve assembly disposed within at least one of said spacer or shaft, said spacer valve assembly configured to allow selectively allow an expansion medium to flow into said spacer cavity to be selectively expand said spacer from a retracted position to an expanded position.
An implant delivery system comprising:
- an introducer including at least one lumen;
- and
- an implant configured to be received in said lumen, said implant comprising a spacer and a shaft, wherein said spacer defines spacer cavity configured to be expanded from a retracted position while disposed within said lumen of said introducer, and wherein said shaft extends from said spacer and defines an inflation lumen fluidly coupled to said spacer cavity and configured to be fluidly coupled to an expansion medium source.
A method of trans-apically delivering an implant within a heart, said implant including a shaft and a spacer configured to interact with at least a portion of at least one cusp of a mitral valve to at least partially restrict a flow of blood through said heart valve in a closed position, said method comprising.
- trans-apically advancing an introducer through an incision in an apex of said heart into a left ventricle;
- advancing said introducer through said mitral valve into a left atrium;
- advancing said implant through a lumen, defined by said introducer, into said left atrium, wherein said shaft extends within said lumen from said spacer and beyond said incision in said heart;
- introducing an expansion medium through said shaft to expand said spacer;
- locating said spacer within said mitral valve to reduce mitral regurgitation;
- removing said introducer from said heart;
- and
- securing said implant to an external surface of said heart proximate to said apex.
