  • Patent number: 6306491
    Abstract: The present invention is directed to materials that assist respiration of living cells contained in cell-containing systems. The materials form air-filled conduits or channels through which gases, such as oxygen and carbon dioxide, can readily exchange by diffusional means between regions of different gas partial pressures. When the present invention is placed within an aqueous environment, such as cell-culture media or host tissue, the invention provides aid to cellular respiration in cell-containing systems.

  • Patent number: 5258040
    Abstract: The inventive article is a ligament or tendon prosthesis having multiple longitudinally parallel strands of microporous expanded polytetrafluoroethylene, the individual strands having an average porosity greater than 30% in the areas requiring tissue ingrowth. Additionally, strand dimensions and microstructure are selected so that tissue can penetrate throughout. The prosthesis is formed from multiple loops of a single continuous filament. Densified eyelets are formed in the loop for mounting to bone. The strands are twisted 180.degree. or arranged in a loose braid about the prosthesis axis for improved load distribution during bending of the prosthesis.

  • Patent number: 5016354
    Abstract: A circular cutting device for cutting planar material along a predetermined radius utilizing a saw having a blade member. The saw is mounted on a saw base having a raised edge. An end plate has a front end positioned adjacent the saw base raised edge and has an attachment mechanism for securing the end plate to the saw base. An adjustment bar has a longitudinal slot formed therein, the adjustment bar being attached to the end plate at a side opposite to the end plate front edge. An extension bar has an axis extending generally parallel to the axis of the adjustment bar and is slidably movable with respect to the adjustment bar. The extension bar is secured to the adjustment bar along the axes. The extension bar is secured to the material to be cut.
