Abstract
A system for applying a polymer (hydrogel) to the inner surface of a vessel by photopolymerization includes a catheter having a first inflatable member and a guidewire having a second inflatable member. The catheter has an extended tip distal to the first inflatable member that includes multiple perfusion ports. A light emission coil is disposed on the extended tip with individual coil loops interspaced with the perfusion ports. In a method, the guidewire is delivered to a treatment site within a vessel. The catheter is delivered to the treatment site over the guidewire. The inflatable members are inflated to form an enclosed treatment space within the vessel. A photoinitiator is delivered to the enclosed treatment space. Excess photoinitiator is flushed from the treatment space, and a prepolymer is delivered. The prepolymer is cured by light delivered by the light emission coil.
