Abstract
Systems and methods for operating cryoballoon ablation catheters. One example system includes a catheter including a treatment element including an expandable element, a light emitting device positioned and configured to emit light at the expandable element, and an electronic controller coupled to the catheter. The electronic controller is configured to initiate an ablation process by controlling a fluid source to provide fluid to the expandable element of the treatment element and selectively operate the light emitting device during the ablation process.
