Abstract: This document describes implantable medical device systems and methods of using such devices for delivering therapy via temperature modulation. For example, this document describes medical device systems and related methods for the treatment of cardiac arrhythmias by delivering cooling to epicardial tissue. In some embodiments described herein, arrhythmias can be treated by an implantable system for painlessly terminating arrhythmias. The devices and methods provided herein permit prompt termination of atrial fibrillation almost immediately after an episode begins (to prevent persistence) and are effective irrespective of patient age and comorbidities.

Abstract: This document describes implantable medical devices and methods of using such devices. The implantable medical devices include a cardiac lead sized for insertion in a cardiac cavity, the cardiac lead having a distal end and a proximal end and a lead body extending therebetween, a heat exchange module disposed at the distal end of the lead body, the heat exchange module comprising an enclosure having a first surface and a second surface, and one or more temperature sensors located within the enclosure.

Abstract: Implantable thermal therapy devices, systems, and methods are provided for the treatment of pathological conditions including arrhythmias and trauma. The implantable thermal therapy devices and systems are specifically structured to deliver transient cooling to a target tissue, and to gradually dissipate the heat energy transferred from the target tissue to other body masses in a controlled and delicate manner. In some examples, a phase change material can be used to accomplish such a gradual dissipation of the heat.

Abstract: A method and system for management of thermal energy produced during transcutaneous energy transmission to provide power to energize implanted medical devices. A phase changing material (PCM) acts as a heat sink to absorb thermal energy generated during the energy transfer process. The PCM can be thermally coupled to tissue proximate to an implanted medical device, enabling heat generated within the implantable device to be absorbed. The generation of heat during the energy transfer process is primarily caused by eddy currents induced in the implantable device by the magnetic flux produced by the energy transfer system. The PCM can also be used to absorb heat generated by the device producing the magnetic flux that is used to transcutaneously transfer electrical power to recharge a rechargeable power source or energize the implanted medical device.
