  • Patent number: 8114154
    Abstract: An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. Additionally, the instrument is adapted to provide a de-aired, fluid-filled, or gas filled environment in order to minimize and/or prevent air embolism during the implantation procedure. The fluid can contain a drug. A method for deploying the cardiac valve prosthesis includes advancing the instrument to an implant site and independently actuating the radially expandable portions.

    Abstract: A cardiac-valve prosthesis is adapted for percutaneous implantation. The prosthesis includes an armature adapted for deployment in a radially expanded implantation position, the armature including a support portion and an anchor portion, which are substantially axially coextensive with respect to one another. A set of leaflets is coupled to the support portion. The leaflets can be deployed with the armature in the implantation position. The leaflets define, in the implantation position, a flow duct that is selectably obstructable. The anchor portion can be deployed to enable anchorage of the cardiac-valve prosthesis at an implantation site.

  • Patent number: 8099918
    Abstract: An uniquely improved mortar less masonry structure comprising a plurality of concrete masonry units connected to each other by metal bars and metal threaded fasteners thereby forming a reinforcing skeletal system for the masonry to utilize a post tensioned structure. The unique system has been developed with full recessed channels in the masonry unit, anchor bars that fit into the channels and extend across a plurality of masonry units and bolts that act as the tendon for the post tensioning system. This is an improved, rapidly constructed building system that demountably couples each individual masonry unit by an extended bar and bolt system. This extended bar is more efficient and easier to build with as compared to other traditional masonry structures.
