Thin-Wall Polytetrafluoroethylene Tube

View page
US Patent:
60277793, Feb 22, 2000
Filed:
May 24, 1994
Appl. No.:
8/247960
Inventors:
Carey V. Campbell - Flagstaff AZ
Donald G. M. Goffena - Camp Verde AZ
James D. Lewis - Flagstaff AZ
David J. Myers - Camp Verde AZ
Clayton M. Sparling - Flagstaff AZ
Assignee:
W. L. Gore & Associates, Inc. - Newark DE
International Classification:
B29D 2200
B32B 904
US Classification:
428 3691
Abstract:
A thin-wall PTFE (polytetrafluoroethylene) tube in the form of a tube of porous expanded PTFE film wherein the porous PTFE film has a microstructure containing a multiplicity of fibrils oriented substantially parallel to each other. The tube has a wall thickness of less than about 0. 25 mm and is made from at least one first layer and at least one second layer of porous PTFE film, wherein the fibrils of the first and second layers are oriented substantially perpendicular to each other. Preferably the fibrils of the at least one first layer are oriented substantially parallel to the longitudinal axis of the tube and the fibrils of the at least one second layer of porous PTFE film are oriented substantially circumferential to the tube. The first and second layers may be inner and outer layers respectively, or alternatively their relationship may be reversed. Alternatively, either of the first and second film layers may be replaced with alternative reinforcing components such as a braid or at least one reinforcing rib.

Carvable Ptfe Implant Material

US Patent:
60751800, Jun 13, 2000
Filed:
Jul 24, 1997
Appl. No.:
8/900060
Inventors:
Norman J. Sharber - Flagstaff AZ
Kenneth W. Moll - Camp Verde AZ
Karl E. Schwarz - Flagstaff AZ
Clayton M. Sparling - Flagstaff AZ
Assignee:
W. L. Gore & Associates, Inc. - Newark DE
International Classification:
A61F 202
US Classification:
623 11
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.
