Abstract
Systems, and methods for treating valvular regurgitation, prolapse, and other valve problems are described. Some embodiments include occluding and/or obstructing devices that traverse an annulus, some implementations anchor an occluding device via a coil. Some implementations provide systems and methods to bring native leaflets in closer proximity to each other to prevent valvular problems. Some embodiments provide outflow-side solutions that encircle chordae tendineae, while some implementations provide inflow-side solutions via joined tissue anchors that can be cinched together.
Claims20
An occluding device for preventing regurgitation or prolapse at a native heart valve, comprising:
- a central plug having a generally conical shape, wherein the generally conical shape defines a proximal side defining a base of the generally conical shape and a distal side defining a narrow end of the generally conical shape and opposite the base, and a central axis running between the distal and proximal sides;
- and
- a coil possessing at least one turn extending along the central axis;
- wherein the coil is sized to encircle native chordae tendineae of a heart valve and provide a retention force against the central plug.
An occluding device for preventing regurgitation at a native heart valve, comprising:
- a central plug having a generally conical shape, wherein the generally conical shape defines a proximal side being the base of the conical shape and a distal side defining the narrow end opposite the base and a central axis running between the distal and proximal sides;
- and
- a plurality of tissue anchors extending radially from the distal side and sized to capture valvular leaflets against the central plug.
