Abstract:
1. A method of coating a tubular medical device extending from a proximal end to a distal end along a longitudinal axis and having a plurality of openings between an abluminal surface and a luminal surface defining a substantially cylindrical lumen having a first diameter, the method comprising: a. positioning the tubular medical device around a mandrel coating assembly having an axial member of a second diameter that is less than the first diameter of the lumen of the tubular medical device and at least one annular projection extending from the axial member to an outer surface, the annular projection configured to securably retain the tubular medical device around the axial member; b. mounting the tubular medical device on the mandrel coating assembly with a first portion of the luminal surface contacting the annular projection, with at least a second portion of the luminal surface spaced apart from and substantially parallel to the axial member; c. spraying a coating solution spray including a therapeutic agent and a solvent onto the abluminal surface of the tubular medical device mounted on the mandrel coating assembly to coat the abluminal surface of the medical device with the therapeutic agent while a portion of the coating solution spray passes through at least one opening in the medical device and terminates at the axial member without passing the axial member to directly contact the luminal surface of the medical device.
