Abstract: An implant for adding compliance to a blood vessel includes a first elongate rail shaped to contact an inner wall of a blood vessel and a second elongate rail shaped to contact an opposing inner wall of the blood vessel. Connectors extend between the first and second rails for providing a separation therebetween and maintaining the rails at locations on opposing sides of the lumen after implantation. The connectors push the rails outwardly for biasing the blood vessel toward a substantially oval shape. The connectors are preferably flexible for allowing the blood vessel to change shape during use for adding compliance to the blood vessel. The elongate rails are preferably curved or hemi-spherical for conforming to the shape of the inner wall of the blood vessel.

Abstract: A delivery apparatus for a medical device can include a handle, a shaft, a plurality of sleeves, and a suture. The shaft includes a proximal end portion coupled to the handle and is configured to be disposed outside of a patient's body during an implantation procedure and a distal end portion configured to be disposed inside a patient's body during the implantation procedure. Each of the sleeves includes a connection portion coupled to the distal end portion of the shaft and a receiving portion configured to receive an apex of a stent or a prosthetic heart valve. The suture extends through the shaft and the sleeves and is configured for releasably securing the stent or the prosthetic heart valve to the receiving portions of the sleeves.

Abstract: A steerable transseptal punch system and method of using the steerable transseptal punch system to access the left atrium.

Abstract: A steerable guidewire. The steerable guidewire is fabricated includes an outer tube, an inner tube, a hub, and a distal articulating region. The steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire.

Abstract: Devices, systems and methods for shunting, plugging, and device installation via a cinching mechanism are provided. In some instances, a cinching system incorporates two rings and a cord stitched along and between the two rings. In some instances, the two termini of the cord can be pulled to provide a cinching mechanism. In some instances, the cinching system is sheathed within a transcatheter delivery system, which can used to deliver the cinching system to a target site.

Abstract: A sensor implant device comprises a sensor body, a sensor component, and one or more anchoring features coupled to the sensor body and configured to anchor within a blood flow pathway or left atrial appendage.

Abstract: A sensor implant system comprises a shunt body comprising a central flow portion configured for placement at least partially within an opening of a tissue wall and the sensor implant system comprises a sensor implant device comprising a sensor body. The sensor implant device is configured for placement within the opening of the tissue wall and between the central flow portion of the shunt body and an inner wall of the opening of the tissue wall.

Abstract: A method for delivering a prosthetic valve to a native annulus of a heart can include inserting a delivery apparatus into a patient's body, advancing the delivery apparatus to an implantation location within the native annulus, retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath, and after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve.

Abstract: A sensor implant device includes a shunt structure comprising a flow path conduit and a plurality of arms configured to secure the shunt structure to a tissue wall, and a pressure sensor device attached to one of the plurality of arms of the shunt structure. The pressure sensor device comprises one or more sensor elements, an antenna, control circuitry electrically coupled to the one or more sensor elements and the antenna, and a housing that houses the control circuitry.
