Abstract

A percutaneous prosthetic heart valve assembly comprising a radially expandable anchor docking member, the anchor docking member having an unexpanded state and an expanded state, in the expanded state, the anchor docking member comprising a mechanism for receiving and engaging an implantable heart valve and a bioabsorbable gasket member disposed about the anchor docking member, the bioabsorbable gasket member comprising a bioabsorbable polymer material, the bioabsorbable gasket member having an unexpanded and an expanded state.

Claims

1. A percutaneous prosthetic heart valve assembly comprising:

a radially expandable, anchor docking member, the anchor docking member having an unexpanded state and an expanded state, in the expanded state, the anchor docking member comprising a mechanism for receiving and engaging an implantable heart valve;

the implantable heart valve; and

a bioabsorbable gasket member disposed about the anchor docking member, the bioabsorbable gasket member comprising a bioabsorbable polymer material, the bioabsorbable gasket member having an unexpanded and an expanded state,

wherein the implantable heart valve is an annular heart valve having two opposing ends, one the two opposing ends is configured to engage the mechanism of the anchor docking member,

wherein one of said anchor docking member and said annular heart valve comprises detents and one of anchor docking member and said annular heart valve comprises a spring.

2. A percutaneous prosthetic heart valve assembly comprising:

a radially expandable, anchor docking member, the anchor docking member having an unexpanded state and an expanded state, in the expanded state, the anchor docking member comprising a mechanism for receiving and engaging an implantable heart valve;

the implantable heart valve; and

a bioabsorbable gasket member disposed about the anchor docking member, the bioabsorbable gasket member comprising a bioabsorbable polymer material, the bioabsorbable gasket member having an unexpanded and an expanded state,

wherein the implantable heart valve is an annular heart valve having two opposing ends, one the two opposing ends is configured to engage the mechanism of the anchor docking member,

wherein said mechanism for engaging said annular heart valve is a snap fit design comprising one of an annular snap fit design, a ball and socket design, a cantilever snap fit and tongue and groove.

3. A percutaneous heart valve assembly comprising:

a radially expandable anchor docking member, the anchor docking member having an unexpanded state and an expanded state, in the expanded state, the anchor docking member comprising a mechanism for receiving and engaging an implantable heart valve;

a bioabsorbable gasket member disposed about the anchor docking member, the bioabsorbable gasket member comprising a bioabsorbable polymer material, the bioabsorbable gasket member having an unexpanded and an expanded state; and

an annular heart valve, the annular heart valve having a crimped, reduced diameter configuration that radially expands to a larger diameter configuration, the annular heart valve is received and engaged by the anchor docking member, the annular heart valve is removable from the anchor docking member, wherein said mechanism is threaded, or comprises a detent or spring.
