  • Patent number: 8353943
    Abstract: The disclosure relates to an implantable woven graft for bridging a defect in a main vessel near one or more branch vessels. The graft includes a region of reduced density. Reduced density regions are alignable with at least one of the one or more branch vessels, and are suitable for in situ fenestration, for example by perforation. The disclosed examples are particularly suited for bridging abdominal aortic aneurysms.

  • Patent number: 8349002
    Abstract: Adjustable annuloplasty rings for repair of a mitral or tricuspid valve which incorporate at least two separate parts that are adjustably interconnectable to create a ring the circumference of which can be changed in dimension. Rings having interconnections at spaced-apart lateral locations, which interconnections allow bidirectional movement to either shorten or lengthen the ring at either such location, afford a surgeon opportunity to make further adjustments to the dimensions of the annuloplasty ring after its initial partial securing to the heart valve tissue and thereby adjust the AP diameter of the valve being repaired. The mating interconnections at two lateral locations on the ring can be constructed so as to allow hinged movement about an axis defined by the interconnections to permit hinged movement between the two separate parts.

  • Patent number: 8328863
    Abstract: An intravascular stent is provided to be implanted in coronary arteries and other body lumens. The transverse cross-section of at least some of the stent struts have a ratio of polar and bending moments of inertia, which results in optimal resistance to stent twisting. This resistance to twisting ratio for the stent struts minimizes out of plane twisting of the struts or projecting edges of the struts when the stent is expanded from a compressed diameter to an expanded diameter in a coronary artery.

  • Patent number: 8303649
    Abstract: The invention relates to a prosthetic valve for regulating flow through a body lumen. The medical device comprises discrete shaping members, a flexible covering, and a valve member. The discrete shaping members are operatively attached to the flexible covering, such that the medical device may exhibit low radial force and dynamic movement.
