Abstract:
1. A method for repairing a vessel valve with an endoluminal catheter device comprising the steps of: a. introducing said catheter device endoluminally through said vessel to the area downstream of the valve, b. applying distal and proximal cuffs to occlude blood flow in the area of the valve, c. washing the vessel substantially free of blood in the area of the vessel between the cuffs, d. inserting a 360° radially emitting optical fiber through the catheter device, e. irradiating the post-valve segment of the vessel wall with laser radiation from the 360° radially emitting optical fiber to reduce the diameter of the vessel's inner wall in the post valve segment, f. irradiating the pre-valve segment of the vessel wall with laser radiation from the 360° radially emitting optical fiber to reduce the diameter of the vessel's inner wall in the pre valve segment, g. replacing the 360° radially emitting optical fiber by an axially emitting optical fiber, h. applying laser suture points to the valve ring with the axially emitting optical fiber, i. removing the cuffs, and j. assessing the irradiation results.
