Abstract
Method to remove an eccentric vascular obstruction by excision with laser energy, preferably excimer laser energy, delivered through a mobile fiber optic shelf, and collecting the excised section within a housing. Apparatus to perform a surgically smooth excision of an eccentric vascular obstruction whereby a mobile fiber optic shelf delivers excimer laser energy to the obstruction to sever the obstruction from the vessel wall, a housing collects the excised section through a radially located cut-out window, the mobile fiber optic shelf traps the excised section within the housing, and a laser light collector prevents the escape of laser energy after application to the obstruction wherein the excised obstruction is physically removed from a patient's body.
