  • Patent number: 8070802
    Abstract: Valve prostheses are disclosed that are adapted for secure and aligned placement relative to a heart annulus. The valve prostheses may be placed in a non-invasive manner, e.g., via transcatheter techniques. The valve prosthesis may include a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring. Each of the positioning elements defines respective proximal, intermediate, and distal tissue engaging regions cooperatively configured and dimensioned to simultaneously engage separate corresponding areas of the tissue of an anatomical structure, including respective first, second, and third elongate tissue-piercing elements.

  • Patent number: 7753949
    Abstract: Valve prostheses are disclosed that are adapted for secure and aligned placement relative to a heart annulus. The valve prostheses may be placed in a non-invasive manner, e.g., via trans-catheter techniques, and may be positioned/repositioned until proper alignment and positioning is achieved. The valve prosthesis may include a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring, each of the positioning elements defining a first tissue engaging region and a second tissue engaging region spaced from the first tissue engaging region.

    Abstract: Valve prostheses are disclosed that are adapted for secure and aligned placement relative to a heart annulus. The valve prostheses may be placed in a non-invasive manner, e.g., via trans-catheter techniques. The valve prosthesis may include a support ring, a plurality of leaflet membranes mounted with respect to the support ring, and a plurality of retention clip elements. The support structure is advantageously formed from a tubular member or flat stock of shape memory metal. A delivery system for delivery of a valve prosthesis embodying the disclosed support structure is also disclosed.
