Abstract
The invention is directed to a recharging system and associated techniques to recharge an implantable medical device (IMD). In particular, a recharging system according to the invention comprises a headset having an energy delivery module that delivers energy to a power source of an IMD implanted on or within the cranium of a patient. The energy delivery module may comprise a coil for inductive transfer of energy to the power source. The headset may be configured for placement over the head of the patient, and may further only partially cover the top of the head. The energy delivery module may be adjustably coupled to the headset. In some embodiments, the position of the energy delivery module may be adjusted along three or four axes, including a rotational axis, allowing the coil to be placed over an IMD located at any of a variety of locations on or within the cranium.
