Abstract

An endovascular laser treatment device includes an optical fiber and a protective sleeve covering the optical fiber. The optical fiber and the protective sleeve are sized to be axially movable relative to one another between a protected state wherein the distal end of the optical fiber is protected within the sleeve and an operating state wherein the distal end of the optical fiber is outside of the sleeve. The optical fiber is in the protected state during insertion into the vessel or a sheath positioned within the vessel, and once it is inserted, the optical fiber is positioned in the operating state ready for application of laser energy to the target vessel.
