Abstract
The present disclosure relates to implantable neuromodulation devices, and in particular to a wireless power coil in a low profile environment such as with a neurostimulator. Particularly, aspects of the present disclosure are directed to a medical device that comprises a lossy housing surrounding a power supply, and a receiving coil configured to exchange power wirelessly via a wireless power transfer signal and deliver the power to the power supply. The receiving coil is adjacent the lossy housing. The receiving coil is a helical structure with a total rise that is less than or equal to a height of the lossy housing.
