Original Abstract Submitted

devices, systems, and methods for performing cryoablation using a single sized balloon coupled with one or more audio sensors for use in controlling balloon inflation. one example system comprises an electronic controller configured to couple to a balloon catheter comprising a balloon, an inflow lumen for providing a fluid to the balloon, and a microphone sensor is positioned to sense a flow of blood proximal to the balloon. the electronic controller is configured to receive, from the microphone sensor, a signal indicative of a blood flow sound. the electronic controller is configured to control a pump to provide a volume of the fluid to the balloon via the inflow lumen based at least in part on the signal indicative of the blood flow sound.
