US Patent:

20120323304, Dec 20, 2012
Filed:

Dec 19, 2011
Appl. No.:

13/330522
Inventors:

Kyle R. Buckley - Flagstaff AZ, US
Vincent L. Perko - Flagstaff AZ, US
International Classification:

A61F 2/82
B23P 11/02
US Classification:

623 115, 29446
Abstract:

An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.

US Patent:

53637194, Nov 15, 1994
Filed:

Mar 10, 1993
Appl. No.:

8/029261
Inventors:

Jerry L. Johnson - Flagstaff AZ
Vincent L. Perko - Flagstaff AZ
Melanee J. Williams - Flagstaff AZ
Assignee:

W. L. Gore & Associates, Inc. - Newark DE
International Classification:

F16C 110
US Classification:

745024
Abstract:

A mechanical control cable system having a tubular housing coaxially surrounding a portion of a length of control cable and incorporating a tubular umbrella seal affixed to at least one end of the system. The tubular umbrella seal is coaxially affixed at one end to an exposed end of the control cable; the other end of the tubular umbrella seal coaxially surrounds an end of the tubular housing with coaxial clearance adequate to allow the tubular umbrella seal to move axially with respect to the tubular housing over the entire desired range of axial motion.

US Patent:

56365519, Jun 10, 1997
Filed:

Dec 30, 1994
Appl. No.:

8/366697
Inventors:

Daniel F. Davidson - Flagstaff AZ
Jerry L. Johnson - Flagstaff AZ
David J. Myers - Camp Verde AZ
Vincent L. Perko - Flagstaff AZ
Assignee:

W. L. Gore & Associates, Inc. - Newark DE
International Classification:

F16C 110
US Classification:

745025
Abstract:

A method of making a mechanical cable having a steel wire core, a layer of fluoropolymer adhesive covering the steel wire core, and an outer layer of porous PTFE covering the layer of fluoropolymer adhesive. The mechanical cable may be a component of a mechanical cable system wherein the mechanical cable slides axially or rotates within a surrounding support tube. The support tube preferably has an inner surface comprised of non-porous PTFE. The support tube may optionally incorporate a contamination seal at the ends of the support tube to reduce the entrance of contaminating dirt and water into the system. The layer of porous PTFE covering the steel wire core may optionally be filled with a lubricating and abrasion resistant filler such as graphite.

Filed:

Mar 31, 2020
Appl. No.:

16/836190
Inventors:

- Newark DE, US
Vincent L. Perko - Flagstaff AZ, US
International Classification:

A61F 2/07
Abstract:

An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.
