DEVICES, SYSTEMS, AND HYBRID METHODS FOR ATRIAL APPENDAGE OCCLUSION USING LIGHT CURE

摘要

Atrial appendage occlusion devices, systems, and hybrid methods of using the same that employ the application of light having a desired wavelength range. The devices of the present disclosure comprise a telescoping catheter assembly configured to isolate an atrial appendage cavity and, using the optical fiber(s), cure any adhesive present within the cavity. Systems are also described comprising the previously mentioned catheter assembly for curing adhesive, as well as an independent suction/injection tool for delivering aspiration and/or adhesive to the LAA cavity and a thoracoscopic camera for optical visualization of the technique. Hybrid methods for using such systems in the treatment of atrial appendage occlusion are also provided.

1. A device for occluding an atrial appendage of a heart and delivering light thereto, the device comprising:
a tubular shaft sized and shaped for insertion into a heart, the shaft comprising a proximal end, an open distal end, and at least one lumen extending therebetween; a balloon coupled to the distal end of the shaft, the balloon configured for inflation and deflation; a patch removably coupled with the distal end of the shaft, the patch configured to occlude an ostium of an atrial appendage cavity when positioned thereover; a catheter sized and shaped for slidable insertion into the lumen of the shaft, the catheter comprising a proximal end, a distal end having at least one opening, and an interior extending between the proximal and distal ends thereof; and at least one optical fiber disposed within the interior of the catheter, each optical fiber configured to emit light having a range of wavelengths, wherein when light is emitted from the at least one optical fiber, the light is communicated through the at least one opening of the distal end of the catheter.
