ABSTRACT:
An endovascular laser treatment device designed to be used with an optical fiber to treat venous diseases such as varicose veins is provided. The device includes a spacer that positions the distal end of the optical fiber away from the inner wall of the blood vessel during delivery of laser energy to provide an even distribution of thermal energy around the vessel, thereby avoiding vessel perforation and incomplete vessel collapse.
