More particularly, the method comprises surgically implanting an electrical stimulation lead and/or catheter that is in communication with a predetermined site which is coupled to a signal generator and/or infusion pump that release either an electrical signal and/or a pharmaceutical resulting in stimulation of the predetermined site thereby treating the mood and/or anxiety.
Abstract:
A charging energy control system may include an implantable medical device (IMD) and an external charger. The IMD receives charging energy to recharge the battery during a charging energy acceptance period and rejects the charging energy during an actual charging energy rejection period. The external charger transmits the charging energy to the IMD in order to recharge the battery. The external charger may include a charging controller configured to determine the charging energy rejection period, and regulate the charging energy during which the charging controller predicts a predicted charging energy rejection period of the IMD based on the actual recharging energy rejection period. The charging controller is configured to cease or reduce transmission of the charging energy during a charging energy conservation period that is at least a portion of the predicted charging energy rejection period.

Abstract:
An implantable stimulation system including an epidural lead for spinal cord stimulation that includes a paddle having an array of electrodes coupled to conductors within the lead body. The paddle includes score lines that extend along the length and width of either the front or back facets of the paddle portion. The score lines increase the flexibility of the paddle in both the length and width directions which facilitate the implantation of the paddle within the epidural space of the spinal cord, and further permits the paddle to conform more uniformly to the target area of implantation to minimize the gap between the electrodes and targeted fibers.
