ABSTRACT:
A device is described which includes an optical fiber or fiber bundle for transmission of laser energy with a proximal end for connection to a laser source and a distal end to which a heat generating tip or cap is securely, but detachably, affixed with a hot-melt adhesive. The heat generating tip serves to generate heat by absorption of laser energy for cauterization of tissue surrounding the neck of an aneurysm or other vascular opening to be occluded. The device is used for intravascular laser coagulation of arteries, veins, aneurysms, vascular malformations and arteriovenous fistulas. The heat generating tip of the device is positioned intravascularly within the neck of the aneurysm or other vascular opening to be occluded and laser energy is transmitted through the optical fiber to heat the tip and thereby coagulate the tissue surrounding the tip.
