Abstract
The present disclosure relates to implantable neuromodulation devices, and in particular to a wireless power coil for a neuromodulation device that is to be implanted in a minimally invasive manner, for example, through a trocar or cannula. Particularly, aspects of the present disclosure are directed to a medical device that includes 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 spaced a predetermined distance from the lossy housing. The medical device further includes a gap provided between the lossy housing and the receiving coil on a vertical plane, and a spacer that fills in at least a portion of the gap to maintain the lossy housing a predetermined distance from the receiving coil.
