Abstract: A prosthetic valve includes a tubular frame, a multi-leaflet valve, movable rods, and a flange. The frame includes a lattice, an inflow end portion, and an outflow end portion. The frame is movable between radially collapsed and expanded states. The lattice deflects as the frame moves between the radially collapsed and expanded states. The valve is disposed within and coupled to the frame and is configured to allow one-way blood flow therethrough. The rods are coupled to the lattice of the frame and are configured to facilitate movement of the frame between the radially collapsed and expanded states. The flange is coupled to and extends radially outwardly from the frame and includes deflectable petals. The petals include a first petal having a first length and a second petal having a second length, and the first length is different than the second length.

Abstract: A catheter includes proximal and distal sections, a shaft coupled between the proximal and distal sections, and optical fibers extending through the shaft and to the distal section of the catheter. The distal section includes a support structure that includes a proximal end, a distal end, reflective elements, and a cap disposed over a portion of the distal end of the support structure. The proximal end includes alignment receptacles. Each of the optical fibers is inserted into corresponding ones of the alignment receptacles and the alignment receptacles are shaped to maintain the optical fibers straight in the support structure. The distal end includes orifices facing different directions. Each of the optical fibers is optically aligned with corresponding ones of the lenses, reflective elements, and orifices such that the optical fibers in the support structure are straight. The cap includes optical ports aligned with the orifices.

Abstract: A method of implanting a prosthetic heart valve includes advancing a prosthetic heart valve to an implantation location within a patient's body, positioning the prosthetic heart valve within a native heart valve annulus, expanding a frame of the prosthetic heart valve from a first contracted configuration to a first expanded configuration, and then contracting the frame to a second contracted configuration. The prosthetic heart valve may be repositioned and then re-expanded from the second contracted configuration to a second expanded configuration. The prosthetic heart valve is preferably released from the delivery apparatus while in the second expanded configuration. Releasing the prosthetic heart valve from the delivery apparatus may result in radial expansion of a flange portion of the prosthetic heart valve.

Abstract: Embodiments of aortic occlusion devices are described herein that include radially expandable and collapsible proximal and distal end portions, such as annular self-expanding stents or frames, that are configured to radially expand within an aorta to secure the device within the aorta. The devices can also include a catheter extending axially between the distal end portion and the proximal end portion and a porous covering, or filter, positioned around the catheter and between the proximal end portion and the distal end portion and configured to filter emboli from blood flowing into upper-body arteries. The device can further include a one-way valve positioned at or adjacent to the distal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.

Abstract: An annuloplasty ring, configured for implantation in the annulus of a heart valve, comprising multiple segments each of which are geometrically shaped from a three dimensional perspective to conform to the anatomic shape of the valve annulus. In one embodiment, at least one of the multiple segments of the annuloplasty ring is configured to facilitate a reduction of tension on heart valve tissue and eliminate a substantial portion of potential pressure or force that may be applied to the atrio-ventricular node by the annuloplasty ring when inserted into a heart valve. In another embodiment, at least one of the multiple segments of the annuloplasty ring are configured to include an assembly that facilitates selective adjustment of a segment's respective length and/or shape. The adjustment of the length of one of the ring segment's results in an adjustment of at least one angle between at least one set of other ring segments, thereby causing an adjustment to the geometric characteristics of the ring.
