  • Patent number: 9393135
    Abstract: A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics. The stent has a plurality of hoop components interconnected by a plurality of flexible connectors. The hoop components are formed as a continuous series of substantially longitudinally or axially oriented radial strut members and alternating substantially circumferentially oriented radial arc members. The geometry of the struts and arcs is such that when the stent is expanded, it has very high strains within a relatively small region.

The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics. The stent has a plurality of hoop components interconnected by at least one flexible connector. The hoop components are formed as a continuous series of alternating substantially longitudinally oriented strut members and connector junction struts, whereas the longitudinal strut is connected to the connector junction strut by alternating substantially circumferentially oriented arc members.

  • Patent number: 8562680
    Abstract: A graft ligament anchor comprises a graft ligament engagement member disposed in an opening in a bone, the graft ligament engagement member being arranged to receive a graft ligament alongside the engagement member, and a locking member for disposition in the opening, and at least in part engageable with the graft ligament engagement member. Movement of the locking member in the opening causes the locking member to urge the engagement member, and the graft ligament therewith, toward a wall of the opening, to secure the graft ligament to the wall of the opening. A method for attaching a graft ligament to a bone is also provided.

  • Patent number: 8551154
    Abstract: This invention relates generally to expandable intraluminal medical devices for use within a body passageway or duct, and more particularly to an optimized stent having asymmetrical strut and loop members, wherein at least one pair adjacent radial strut members have unequal axial lengths.
