Abstract: A retrieval catheter and methods of use are described for removing a heart valve therapy such as a leaflet clip or artificial leaflet cord. The retrieval catheter can include a cutting element and a basket, piercing element, clamping mechanism, or similar grasping device. The method includes delivering a catheter to the region of the heart valve therapy and then manipulating the catheter and associated instruments to cut tissue as necessary and then remove the heart valve therapy and withdraw the catheter.

Abstract: Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit. More specifically, an electrical arc is generated between two spaced-apart electrodes disposed within a fluid-filled balloon, creating flow and pressure waves. In some embodiments, the electrodes are spaced apart across relatively long distances to create a stronger shock. In some embodiments, the saline ionically conducting between the electrodes is confined to reduce parasitic heating. In some embodiments, the balloon is partially deflated during arc generation.

Abstract: Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit. More specifically, an electrical arc is generated between two spaced-apart electrodes disposed within a fluid-filled balloon, creating a subsonic pressure wave. In some embodiments, the electrodes comprise a plurality of points that allow the electrical arc to form at any one of the plurality of points to, among other things, extend the electrode life.

Abstract: Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.
