Beschreibung
Zusammenfassung:	An uncured or partially cured, collagen-based material is delivered to a selected site in a blood vessel and is crosslinked in the blood vessel by laser energy or other suitable energy to form an endovascular stent. The collagen-based material can be delivered to the blood vessel as a coating on an inflatable balloon mounted on the distal end of a catheter. The collagen-based material can also be delivered to the blood vessel in liquid form. The liquid collagen-based material is forced through a porous balloon to form either an imperforate tubular configuration or a tubular mesh configuration. The collagen-based material is preferably crosslinked by laser radiation carried through an optical fiber to a diffusing tip located within the balloon.
