ABSTRACT:
A method of making a catheter balloon or other tubular medical device or component, in which a sheet of polymeric material is wrapped on a mandrel and heated to fuse sections of the wrapped sheet together to form a tube. The mandrel has a metallic core and a jacket on an outer surface of the metallic core, and the wrapped sheet of polymeric material is heated without corroding the metallic core of the mandrel. In a presently preferred embodiment, the sheet is formed of a fluoropolymeric material, and the resulting fluoropolymeric tube forms at least a layer of a catheter balloon.
