Abstract
A docking device for securing a prosthetic valve at a native valve includes a coil having a plurality of helical turns when deployed at the native valve, and a guard member attached to the coil. The guard member is movable between a radially compressed state and a radially expanded state. The guard member includes a plurality of anchor members and a plurality of expandable members. The anchor members are not radially movable relative to the coil when the guard member moves from the radially compressed state to the radially expanded state. The expandable members project radially outwardly from the coil when the guard member moves from the radially compressed state to the radially expanded state.
Claims20
A docking device for securing a prosthetic valve at a native valve, the docking device comprising:
- a coil comprising a plurality of helical turns when deployed at the native valve;
- and
- a guard member attached to the coil and is movable between a radially compressed state and a radially expanded state,
- wherein the guard member comprises a plurality of anchor members and a plurality of expandable members,
- wherein the anchor members are not radially movable relative to the coil when the guard member moves from the radially compressed state to the radially expanded state,
- wherein the expandable members project radially outwardly from the coil when the guard member moves from the radially compressed state to the radially expanded state.
A docking device for securing a prosthetic valve at a native valve, the docking device comprising:
- a coil comprising a plurality of helical turns when deployed at the native valve;
- and
- a guard member attached to the coil and is movable between a radially compressed state and a radially expanded state,
- wherein the guard member comprises a plurality of anchor members fixedly attached to the coil and a plurality of expandable members that can cantilever over respective anchor members,
- wherein the guard member is axially stationary relative to the coil.
A method of making a docking device for securing a prosthetic valve at a native valve, the method comprising:
- receiving a tube comprising a shape memory material;
- transforming the tube into a cylindrical mesh structure comprising a plurality of anchor members and a plurality of expandable members that are interconnected to form a unitary piece;
- and
- shape setting the plurality of expandable members so that the plurality of expandable members cantilever over respective anchor members and project radially outwardly when no external force is applied to the plurality of expandable members.
