Abstract

A cryogenic balloon catheter system includes an inflatable balloon, a handle assembly and a pressure sensor. The inflatable balloon has a balloon interior. The pressure sensor senses a balloon pressure within the balloon interior. In various embodiments, the pressure sensor can be positioned within the balloon interior, within the handle assembly and / or between the inflatable balloon and the handle assembly. The cryogenic balloon catheter system also includes a controller that receives a sensor output from the pressure sensor. The controller can control injection of a cooling fluid to the balloon interior and / or removal of the cooling fluid from the balloon interior based upon the sensor output. The cryogenic balloon catheter system can also include an injection proportional valve, an exhaust proportional valve, an injection flow sensor and / or an exhaust flow sensor.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application Serial No. 62 / 479,798, filed March 31, 2017, entitled "CRYOGENIC BALLOON PRESSURE SENSORASSEMBLY." To the extent permitted, the contents of US Provisional Application Serial No. 62 / 479,798 are incorporated herein by reference. Background technique [0003] Arrhythmias involve abnormalities in the conduction of the heart and are a major cause of stroke, heart disease, and sudden cardiac death. Treatment options for patients with cardiac arrhythmias include drug therapy, implantable devices, and catheter ablation of cardiac tissue. [0004] Catheter ablation involves delivering ablation energy to the tissue within the heart to prevent abnormal electrical activity from depolarizing the heart muscle cells out of sync with the heart's normal conduction patterns. This procedure is performed by positioning the tip of the catheter adjacent to the lesion or target tissue in the heart....
