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 and forced through a porous balloon to form a tubular configuration. The collagen-based material is preferably crosslinked by laser radiation carried through an optical fiber to a diffusing tip located within the balloon. In another embodiment, an endovascular stent is formed by rolling a flexible sheet of biologically-compatible material onto an outside surface of an inflatable balloon. A crosslinkable collagen-based adhesive is used to adhere overlapping portions of the sheet together in the blood vessel and can be used to attach the stent to an inside surface of the blood vessel. The collagen-based adhesive is crosslinked in the blood vessel by application of laser energy or other suitable energy. A photodegradable adhesive can be used on an inside surface of the stent to releasably attach the stent to the inflatable balloon.
A method for treating a selected region of a blood vessel, comprising the steps of: applying a crosslinkable adhesive material to one side of a flexible sheet of biologically-compatible material; rolling the sheet of biologically-compatible material so that portions of the sheet overlap to form a ge
A method for treating a selected region of a blood vessel, comprising the steps of: applying a crosslinkable adhesive material to one side of a flexible sheet of biologically-compatible material; rolling the sheet of biologically-compatible material so that portions of the sheet overlap to form a generally tubular body, said tubular body having said crosslinkable adhesive material between overlapping portions of the sheet; delivering the tubular body to the selected region of the blood vessel; and applying energy to the tubular body at the selected region of the blood vessel so as to crosslink the adhesive material and cause overlapping portions of the sheet to adhere together to thereby form a stent in the blood vessel.
