7314364, Jan 1, 2008

Filed:

Jan 18, 2005

Appl. No.:

11/038841

Inventors:

Timothy P. Mahoney - Temecula CA, US
Michael J. Flick - Lake Elsinore CA, US

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

B29C 49/62
B29C 49/64

US Classification:

425182, 425393, 425526, 425384

Abstract:

A method of making a catheter balloon, and a balloon formed thereby, in which a polymeric tube is radially expanded in a mold having a wall with an outer surface and an inner surface defining a chamber, and having at least a section with one or more channels in the wall. The channels result in improved transfer of heat to the polymeric tube within the chamber of the mold during blow molding of the tube to form a balloon, so that the tube is heated more quickly and evenly. One aspect of the invention is directed to a balloon having sections with improved thin walls.
