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

摘要

Atrial appendage occlusion devices and 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 coupled with an adhesive delivery device and a suction source, and comprise at least one optical fiber disposed therein. The catheter assembly is configured to isolate an atrial appendage cavity, deliver suction and adhesive thereto, and, using the optical fiber(s), cure the adhesive present within the cavity all without withdrawing any components of the catheter assembly from the body. Methods for using such device in the treatment of atrial appendage occlusion are also provided.

主权项

1. A device for occluding an atrial appendage of a heart 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 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 at least one lumen extending between the proximal and distal ends thereof; an adhesive delivery device coupled with the proximal end of the catheter and in communication with at least one lumen of the catheter; and at least one optical fiber disposed within one of the at least one lumens of the catheter and 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.
