Abstract
A prosthetic device for treating a mitral valve includes a prosthetic insert member insertable between leaflets of mitral valve. The insert member has an elongated cross-sectional profile for conforming to gap between leaflets of a mitral valve. The device also includes an anchoring member for attachment to heart tissue for maintaining the insert member in the mitral valve. The insert member includes a valve that permits one-way blood flow therethrough. An anchoring member secures the prosthetic insert member to a heart wall.
Claims20
A prosthetic device for a mitral valve comprising:
- a longitudinal axis;
- an insert member including an inner support layer and an outer layer, the inner support layer comprising a shape-memory metal, the outer layer comprising fabric,
- an inflow end, and an outflow end, the longitudinal axis passing through the inflow end and the outflow end,
- a passageway extending through the insert member along the longitudinal axis, and
- a one-way valve disposed within the passageway, the one-way valve including one or more flaps, the one-way valve permitting blood flow from the inflow end to outflow end, wherein
- the insert member in the compressed state has a diameter suitable for delivery in a delivery sheath,
- the insert member has an expanded state and a compressed state,
- the insert member in the expanded state has a cross-sectional profile transverse to the longitudinal axis in which sides of the insert member are shaped for creating a tight seal against native mitral valve leaflets, the insert member in the expanded state sufficiently rigid to substantially maintain a shape thereof;
- and
- an anchoring member extending longitudinally from the insert member, the anchoring member including a proximal end portion and a distal end portion, the proximal end portion coupled to the insert member, the distal end portion of the anchoring member including a self-expanding, flower-shaped anchor having a compressed configuration and an expanded configuration, the flower-shaped anchor suitable for anchoring to a left ventricular wall.
