Patent ID: 8397666

Claim:
A mandrel coating assembly for applying a therapeutic agent to at least one tubular medical device when loaded onto the assembly, the tubular medical device including an outer surface and a luminal surface and a plurality of openings therethrough, the assembly comprising: a first member having a proximal end and a distal end and extending along a longitudinal axis, the first member having an outer surface with an outer diameter and a luminal surface defining a substantially cylindrical lumen with a luminal diameter, wherein a portion of the first member has a plurality of perforations between the outer surface and the luminal surface, where the perforations are configured and sized to be in communication with said openings of the at least one tubular medical device when loaded; a second member having a proximal end and a distal end and extending along the longitudinal axis, at least one portion of the second member being disposed within the first member lumen, the second member having a portion including at least one fluid flow channel in fluid communication with the perforations of the first member, wherein the second member has an outer surface adjacent to the at least one fluid flow channel and where a portion of said outer surface is dimensioned to contact the luminal surface of the first member along substantially an entire length of the second member to define the at least one fluid flow channel; and a vacuum means in fluid communication with the at least one fluid flow channel of the second member, the vacuum means configured to remove excess therapeutic agent when applied.
