Abstract
Systems and methods for mitral valve repair having a docking station and a valve implant. The docking station is an anchoring device having a helix structure. The valve implant is made of an expandable frame and a valve, and is radially expandable to a diameter that is at least the same as an expanded diameter of the anchoring device. The method of delivering the docking station and valve implant is performed by inserting the components through device delivery catheters.
Claims19
A system for mitral valve repair comprising:
- a docking station and a valve implant,
- wherein the docking station comprises an anchor that comprises a helix structure having at least two turns;
- wherein the valve implant comprises an expandable frame and a valve, and the valve implant is radially expandable to at least an external valve diameter that is the same as an internal anchor diameter when the anchor is in an expanded position, and
- wherein the system is configured such that, when implanted at a native mitral valve, the docking station and the valve implant will not contact an entire circumference of a native annulus of the native mitral valve.

A system, comprising:
- an anchor, wherein the anchor comprises a superelastic material configured to transition from an first configuration, in which the anchor is straightened for transvascular delivery to a native heart valve, to a second configuration comprising at least two circular turns;
- a replacement valve, wherein the replacement valve comprises an expandable frame and a valve body, and wherein the replacement valve can transition from a collapsed configuration, for transvascular delivery to the native heart valve, to an expanded configuration, wherein the anchor and the replacement valve are configured such that, when delivered to the native heart valve, expansion of the replacement valve from the collapsed configuration to the expanded configuration inside the anchor can trap native leaflets of the native heart valve between the replacement valve and the anchor and thereby secure the replacement valve and the anchor at the native heart valve, and
- wherein the replacement valve in the expanded configuration has a diameter smaller than a major axis of the native heart valve.
A system, comprising:
- an anchor, wherein the anchor comprises a superelastic material configured to transition from an first configuration, in which the anchor is straightened for transvascular delivery to a native heart valve, to a second configuration comprising at least two circular turns;
- a replacement valve, wherein the replacement valve comprises an expandable frame and a valve body, and wherein the replacement valve can transition from a collapsed configuration, for transvascular delivery to the native heart valve, to an expanded configuration, wherein the anchor and the replacement valve are configured such that, when delivered to the native heart valve, expansion of the replacement valve from the collapsed configuration to the expanded configuration inside the anchor can trap native leaflets of the native heart valve between the replacement valve and the anchor and thereby secure the replacement valve and the anchor at the native heart valve, and
- wherein the at least two circular turns of the anchor in the second configuration and the replacement valve in the expanded configuration each have a diameter smaller than a major axis of the native heart valve.
A system, comprising:
- an anchor, wherein the anchor is transitionable between a straightened configuration for transvascular delivery through an opening in a femoral vein to a native heart valve and a deployed configuration comprising at least two circular turns;
- a replacement valve, wherein the replacement valve comprises an expandable frame having posts to form commissural points and a valve body, wherein the valve body comprises multiple pieces of animal tissue sewn or bonded together and to the posts that can open to allow blood flow therethrough and close to prevent blood flow therethrough;
- wherein the replacement valve can transition from a collapsed configuration, for transvascular delivery through the opening in the femoral vein to the native heart valve, to an expanded configuration;
- wherein the anchor can be transvascularly delivered to the native heart valve such that at least one of the at least two circular turns encircles native leaflets of the native heart valve, and the replacement valve is configured such that the replacement valve can be transvascularly delivered to the native heart valve in the collapsed configuration and expanded to the expanded configuration inside the anchor and thereby secure the replacement valve and the anchor at the native heart valve, and
- wherein the replacement valve in the expanded configuration is configured to have a diameter smaller than a major axis of the native heart valve, such that native commissural regions of the native heart valve extend radially beyond the replacement valve.

- wherein the at least two circular turns of the anchor in the deployed configuration are configured to have a diameter smaller than a major axis of the native heart valve, such that native commissural regions of the native heart valve extend radially beyond the at least two circular turns of the anchor.
