  • Publication number: 20070135900
    Abstract: A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents.

  • Publication number: 20060030930
    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.

  • Publication number: 20060009837
    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 and the method for designing and optimizing said strut and loop members in a continuously variable fashion. In one embodiment of the invention the resulting stent includes one or more members each having at least one component. The component has non-uniform cross-sections to achieve near-uniform stress distribution along the component when the component undergoes deformation.

  • Publication number: 20050149162
    Abstract: An apparatus for compressing a coiled stent having at least one protrusion, such as an enlarged coil disposed at the end of the stent, has a mandrel insertable into a lumen of the stent for holding the stent by friction and a coil compressor coupled to the mandrel. The mandrel is rotatable on an axis relative to the coil compressor and the coil compressor has a tab extending therefrom towards the mandrel. A stent is placed on the mandrel with the enlarged coil extending toward the coil compressor. The tab presses the enlarged coil inwardly toward the lumen of the stent when the mandrel is rotated relative to the coil compressor.

  • Patent number: 6709436
    Abstract: An intramedullary nail structure is formed with opposing dynamization windows, and spacers of a bioresorable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. Tale nail is used with a bone fastener such as a bone screw which is advanced transversely through the bone and into the spacer, preferably in a bicortical attachment with the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the intramedullary nail. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site.

  • Publication number: 20030135274
    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.
