Abstract:
1. A method for endovascular laser treatment of a varicose vein method comprising: inserting into a diseased vein an optical fiber and a spacer arranged near a distal end of the optical fiber; injecting a tumescent agent into tissue adjacent to the diseased vein; and applying laser energy through the distal end of the optical fiber while longitudinally withdrawing the inserted optical fiber and spacer through the diseased vein such that the spacer positions the distal end of the optical fiber away from the inner wall of the diseased vein to prevent the distal end of the optical fiber from contacting the inner wall of the diseased vein and to direct the laser energy into a lumen of the diseased vein and blood within the lumen, the application of laser energy causing closure of the diseased vein to thereby treat the varicosity.
