Abstract

An intravascular catheter system for treating a condition in a body includes a catheter shaft, a first inflatable balloon and a plurality of electrodes. The first inflatable balloon is positioned neara distal end of the catheter shaft. The first inflatable balloon moves between an inflated state and a substantially deflated state. In the inflated state, the first inflatable balloon has a maximumcircumference. The plurality of electrodes are attached to the first inflatable balloon away from the maximum circumference of the first inflatable balloon. In some embodiments, the plurality of electrodes are attached to the inner surface of the first inflatable balloon. In various embodiments, the intravascular catheter system can also include two or more flex circuits that substantially face one another when the first inflatable balloon is in the substantially deflated state.

Description

[0001] related application [0002] This application claims U.S. Provisional Application Serial No. 62 / 452,973, filed January 31, 2017, entitled "CRYOGENIC BALLOON CATHETER ASSEMBLY WITH SENSOR ASSEMBLY" ASSEMBLY" has priority to U.S. Provisional Application Serial No. 62 / 613,722. To the extent permitted, the contents of US Provisional Application Serial Nos. 62 / 452,973 and 62 / 613,722 are hereby incorporated by reference. Background technique [0003] Cardiac arrhythmias involve abnormalities in the electrical conduction of the heart and are a major cause of stroke, heart attack, and sudden cardiac death. Treatment options for patients with cardiac arrhythmias include drugs, implantable devices, and catheter ablation of heart tissue. [0004] Catheter ablation involves the delivery of ablation energy to tissue within the heart to stop the abnormal electrical activity of depolarized heart muscle cells that are out of sync with the heart's normal conduction patterns. The proc...
