    Abstract: Stimulation lead includes an elongated lead body having distal and proximal ends and wire conductors extending therebetween. The stimulation lead also includes a lead paddle having a multi-dimensional array of electrodes positioned along a contact side of the lead paddle. The electrodes are electrically coupled to the wire conductors. The lead paddle includes a paddle body and a conductor organizer disposed within the paddle body. The conductor organizer has multiple channels extending along the lead paddle. The channels receive the wire conductors and retain the wire conductors in a designated arrangement with respect to the lead paddle. The conductor organizer has openings to the channels. The wire conductors extend through the openings and are terminated to the respective electrodes.

    Abstract: Implementations described and claimed herein provide paddle leads for dorsal root ganglia (DRG) stimulation and methods of implanting the same. In one implementation, the paddle lead has a small profile facilitating deployment into a target space in the neuroforamen dorsal to the DRG and below the vertebral lamina. A paddle body of the paddle lead may include a living hinge and/or a contoured profile to further facilitate implantation in the target space. For suture assisted deployment as well as to resist migration of the paddle lead once deployed, the paddle lead may include a suture loop configuration. The paddle lead further includes an electrode array having electrode contacts arranged in a two dimensional configuration pattern to create an electrical field optimized for stimulation of the DRG.

    Abstract: A method of forming a stimulation lead includes forming an implantable lead body, including helically winding at least one cable about a mandrel to form a coiled cable assembly in a first, restrained state. Helically winding the at least one cable includes applying a tensile force to the at least one cable as the at least one cable is wound about the mandrel. Forming the lead body also includes releasing the tensile force from the at least one cable to allow the coiled cable assembly to release stored mechanical energy and transition from the restrained state to a second, relaxed state in which the coiled cable assembly is substantially free of stored mechanical energy. The method further includes subjecting the lead body to a reflow process by applying heat to the lead body, where the tensile force is released prior to the lead body being subjected to the reflow process.

    Abstract: A neurostimulation (NS) system and method are provided. The NS system includes an array of electrodes positioned within a patient. The array of electrodes includes an active electrode. The active electrode is configured to be a cathode electrode located proximate to neural tissue of interest that is associated with a target region. The NS system includes an anode electrode and an electromagnetic interference (EMI) antenna. A control circuit is configured to control delivery of a NS therapy during a therapy delivery interval. The NS therapy is to be delivered between the anode electrode and the active electrode. The NS system develops a residual voltage between the anode electrode and the active electrode over the therapy delivery interval. A current regulator (CR) circuit is connected to the cathode electrode. The CR circuit is configured to control current flow through the cathode electrodes. During a discharge operation, the control circuit is configured to manage the CR circuit to control a discharge current flow over the discharge operation to discharge the residual voltage after therapy delivery in a manner that follows an actively emulated passive discharge (AEPD) profile. During the discharge operation, the CR circuit is connected to the inactive electrode. The CR circuit receives, as a first input, an EMI feedback signal from the EMI antenna. The CR circuit is configured to regulate the discharge current flow through the active electrode based on the EMI feedback signal, to maintain the AEPD profile over the discharge operation while in a presence of an EMI event.
