OPTICAL FIBER WITH DETACHABLE METALLIC TIP FOR INTRAVASCULAR LASER COAGULATION OF ARTERIES, VEINS, ANEURYSMS, VASCULAR MALFORMATIONS AND ARTERIOVENOUS FISTULAS

摘要

ABSTRACT OF THE DISCLOSUREA device is described which includes an optical fiber orfiber bundle for transmission of laser energy with a proximal endfor connection to a laser source and a distal end to which a heatgenerating tip or cap is securely, but detachably, affixed with ahot-melt adhesive. The heat generating tip serves to generateheat by absorption of laser energy for cauterization of tissuesurrounding the neck of an aneurysm or other vascular opening tobe occluded. The device is used for intravascular laser coagula-tion of arteries, veins, aneurysms, vascular malformations andarteriovenous fistulas. The heat generating tip of the device ispositioned intravascularly within the neck of the aneurysm orother vascular opening to be occluded and laser energy is trans-mitted through the optical fiber to heat the tip and therebycoagulate the tissue surrounding the tip.
