Abstract
Methods of coating a stent subsequent to mounting or crimping of the stent on a balloon of a catheter assembly are disclosed. One method includes forming a sacrificial layer on a balloon of a catheter assembly; followed by mounting a stent on the balloon, the stent including struts separated by gaps; followed by forming a stent coating on the stent; and followed by removal of the sacrificial layer. Another method includes mounting a stent on a balloon, the stent including struts separated by gaps; followed by forming a sacrificial layer on the balloon in the areas of the gaps between struts of the stent; followed by forming a coating on the stent; and followed by removing the sacrificial layer, wherein the coating remains on an outer surface of the stent.
