Abstract:
1. Apparatus for applying a coating to an endolumenal wall of a medical device, the apparatus comprising: an optical fiber dimensioned to be received within a lumen of a medical device, the optical fiber having a first end and a second end, the second end being adapted to disperse radiation traveling through the optical fiber; a fluid-carrying channel surrounding the optical fiber and having an outer wall with a distal opening adjacent the optical fiber second end, wherein an entire circumference of the second end of the optical fiber is positioned external to the fluid-carrying channel; a supply of a fluid disposed within the fluid-carrying channel to be dispensed onto said endolumenal wall of the medical device adjacent to the optical fiber second end, the fluid having a photo-activated component; a source of radiation coupled to the optical fiber first end, the radiation being transmittable by the optical fiber and interactive with the photo-activated component of the fluid; and a transit control configured to move at least one of the second end of the optical fiber and the fluid-carrying channel longitudinally through a selected portion of the medical device lumen at a controlled rate.
