Abstract
A trans-femoral implant includes an anchor assembly and a balloon assembly configured to be separately delivered to an implant site within a heart. Once delivered, the anchor assembly and balloon assembly may be coupled to form an implant within the heart. The balloon anchor may include a fluid inflatable balloon that may be selectively filled via a balloon filling valve. The balloon assembly may further include a latching mechanism that may couple with a distal end of the anchor assembly, such that the length of the implant may be adjusted within the heart.
Claims21
An implant, comprising:
- a balloon spacer assembly, the balloon spacer assembly comprising:
- a balloon spacer defining a spacer cavity configured to be expanded from a deflated condition to an expanded condition with a filling fluid;
- a balloon filling valve disposed within and fluidly coupled to said spacer cavity, wherein said balloon filling valve comprises a lumen, is configured to be fluidly coupled to a source of said filling fluid and to selectively allow the introduction and withdrawal of said fluid into and out of said spacer cavity.
A method of trans-femorally delivering an implant within a heart, said implant comprising an anchor assembly and a balloon assembly configured to be separately delivered and coupled within said heart to form said implant, the method comprising:
- advancing an anchor assembly comprising an anchor through a lumen of a steerable catheter extending through a septum of said heart, into a left atrium, through a mitral valve, and into a left ventrical;
- deploying said anchor assembly such said anchor engages coronary tissue of said heart;
- advancing said balloon assembly through said lumen of said steerable catheter, said balloon assembly comprising a balloon spacer defining a spacer cavity and a balloon filling valve, wherein the spacer cavity is configured to be expanded from a deflated condition to an expanded condition with a fluid;
- coupling a distal portion of said balloon assembly to a proximal portion of said anchor assembly within said heart;
- adjusting a relative position of said balloon assembly to said anchor;
- and
- introducing a fluid from a fluid source through said balloon filling valve to expand said spacer cavity from said deflated condition to said expanded condition.
