Abstract
A method of forming a textured surface on the inner surface of a sheath is provided. The sheath may be used in a delivery system to restrain a self-expanding medical implant in a compressed state. In the method, a sleeve is squeezed against a textured pattern on a mandrel to form a textured surface on the inner surface of the mandrel. The diameter of the mandrel is then contracted before the mandrel is removed from the sleeve.
