20090018487 | Catheter-Based, Dual Coil Photopolymerization System - A system for applying a polymer (hydrogel) to the inner surface of a vessel by photopolymerization includes an inner catheter received within an outer catheter and a fluid channeling structure mounted on the catheters with its proximal end attached to the outer catheter and its distal end attached to the inner catheter. The fluid channeling structure includes an elastomeric sleeve sandwiched between an inner elastic coil and an outer light emission coil. Light emission coil loops are interspaced with elastic coil loops. The light emission coil has a smaller diameter than the elastic coil, drawing the elastomeric sleeve down between loops of the elastic coil to form a helical channel. The coils and sleeve are stretched to provide a narrowed crossing profile for delivery, and are contracted at a treatment site to form a helical cavity between the sleeve and the vessel wall within which to perform interfacial photopolymerization. | 01-15-2009 |
20090171265 | Catheter-Based, Dual Balloon Photopolymerization System - 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. | 07-02-2009 |
20120245607 | METHOD AND SYSTEM FOR TREATING VALVE STENOSIS - A valvuloplasty catheter comprises a balloon or other expansible shell which carries a plurality of scoring elements, typically formed in an elastic, self-closing metal cage. The expansible shell and scoring elements are positioned inside an aortic or other cardiac valve, and the shell expanded to engage the scoring elements against stenotic material which covers the valve leaflets and valve annulus. The scoring elements uniformly distributed force to break up the stenotic material, and the cage further contributes to rapid balloon deflation allowing shortening of the treatment time. | 09-27-2012 |
