Abstract
Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils (e.g., a primary coil and a secondary coil) may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to the primary coil to absorb heat generated during the inductive coupling and reduce temperature increases of the primary coil. In one example, the phase change material may be configured to absorb heat from an energy transfer coil. A housing may be configured to contain the phase change material and a coupling mechanism may be configured to removably attach the housing to the energy transfer coil.
