Patent ID: 7604830

Claim:
A method of coating an endolumenal wall of a lumen of a previously manufactured medical device comprising the steps of: positioning a distal end of an optical fiber within the lumen of the previously manufactured medical device, surrounding the optical fiber with a fluid-carrying channel having an outer wall with a distal opening adjacent the optical fiber distal end, providing a photo-activated chemical within the fluid-carrying channel to be dispensed onto the endolumenal wall of the lumen, coupling the optical fiber to a source of radiation that can be carried by the optical fiber to the distal end of the optical fiber, the radiation being capable of activating the chemical within the lumen, and withdrawing the optical fiber and fluid-carrying channel simultaneously from the lumen at a controlled rate while the radiation is being emitted from the optical fiber distal end to activate the chemical in close proximity to the endolumenal wall.
