  • Carvable PTFE implant material
    Patent number: 6075180
    Abstract: A carvable implant material for use in surgery and especially in plastic and reconstructive surgery. At least two layers of porous PTFE (polytetrafluoroethylene) sheet material are laminated together by an adhesive placed between the adjacent layers of porous PTFE sheet material. Alternatively, a plurality of discrete pieces of porous PTFE may be adhered together by an adhesive. The presence of the adhesive provides a significant increase in stiffness and hence in carvability beyond that possible in a single layer of porous PTFE without the adhesive. Preferred adhesives are thermoplastic fluoropolymers of lower crystalline melt temperature than PTFE, such as FEP or PFA.

  • Process for forming a seamless tube of expanded PTFE from a sheet of expanded PTFE
    Patent number: 6048484
    Abstract: A method of making a seamless, thinwall tube of porous polytetrafluoroethylene. The method involves the use of corresponding male and female dies to deform a precursor sheet of porous PTFE which has been restrained about its perimeter. Preferably the porous PTFE sheet is heated to a temperature of less than the crystalline melt temperature during the tube-forming process. The precursor material is preferably a sheet of porous expanded PTFE and more preferably a multiaxially expanded sheet. This precursor material may optionally have been previously exposed to heat above the melt temperature of PTFE. The inventive tube is as thin or thinner than the precursor sheet.

  • Thin-wall, seamless, porous polytetrafluoroethylene tube
    Patent number: 5620763
    Abstract: A seamless tube of polytetrafluoroethylene having a microstructure of nodes interconnected by fibrils and having a wall thickness of less than about 0.20 mm.

  • Method for producing molded circuit boards
    Patent number: 4811482
    Abstract: A method for producing circuit boards having embedded three-dimensional wiring patterns and exposed mounting pads for receiving surface mounted components and terminals in which the exposed mounting pads are formed by forming junctions between the conductors and a substrate which is in turn used as at least a portion of mold for receiving hardenable material for encapsulating the conductors and forming the circuit board and in which the junctions become exposed to define mounting pads when the substrate is removed.
