US Patent:

6616996, Sep 9, 2003

Filed:

Oct 28, 1994

Appl. No.:

08/331280

Inventors:

Lane A. Keith - Chattanooga TN
Gary G. Massengale - Trenton GA
John T. Riddle - Trenton GA
Ronald B. Roth - Signal Mountain TN

Assignee:

Medsource Trenton, Inc. - Trenton GA

International Classification:

B32B 108

US Classification:

428 358, 428 359, 428 362, 428 363, 428 3691

Abstract:

A novel composite microtubing with variable stiffness over the length of the tubing and continuous process for manufacturing the same is provided. By removing portions of one or more selected layers of the composite microtubing, varying the pick count of a braided layer, and changing the diameter over the length of the microtubing, the stiffness of the microtubing may be varied by a factor of 100 from proximal end to distal end. The continuous process allows a predetermined stiffness pattern to be repeated over a measured length for economical manufacture and results, if desired, in tubing of extremely small diameter and extremely thin tube walls.

Filed:

Apr 21, 1999

Appl. No.:

9/296137

Inventors:

Ronald B Roth - Signal Mountain TN
E. William Darby - Chattanooga TN

Assignee:

HV Technologies, Inc. - Trenton GA

International Classification:

H01L 3500

US Classification:

136201

Abstract:

A novel microtubing and a method of manufacture is provided. The resulting microtubing has at least two thermoelements separated by a resin layer except in defined areas where the insulating resin layer is selectively removed. The resulting microtube provides improved performance, reduced size, increased flexibility, and can be efficiently manufactured.
