Abstract:
1. A method of making a tubular medical device or component formed of a compacted porous polymeric material, comprising: a) positioning heat shrink material on a tube of porous polymeric material, with a mandrel in a lumen of the porous polymeric tube; b) shrinking the heat shrink material by heating the heat shrink material on the porous polymeric tube, to axially compact the porous polymeric tube without increasing the outer diameter of the porous polymeric tube; and c) removing the shrunk material from the compacted porous polymeric tube and removing the compacted porous polymeric tube from the mandrel, to form a compacted porous polymeric layer of an expandable tubular medical device or component having at least one layer.
