Abstract
A method of making a catheter balloon or other expandable tubular medical device or component thereof formed of a compacted porous polymeric material, in which a tube of porous polymeric material is axially compacted, preferably without increasing the outer diameter of the tube, by positioning heat shrink material on the porous polymeric tube and heating the heat shrink material to decrease the length and diameter of the heat shrink material.
