A control module for an electrical stimulation system includes a sealed electronics housing; an electronic subassembly disposed within the electronics housing; one or more connector assemblies coupled to the electronic subassembly; and a rechargeable battery disposed external to the electronics housing. The one or more connector assemblies are configured to receive a lead. The rechargeable battery includes a positive electrode, a negative electrode, and a single battery case attached directly to the sealed electronics housing and forming a sealed cavity that encapsulates both the positive electrode and the negative electrode. The battery case is electrically isolated from each of the positive electrode and the battery electrode.

Synchronized stimulation of cardiac tissue can be implemented by implanting two or more rectifier-based AM receivers into different positions within a subject's heart. Each receiver is tuned to a different frequency, and generates an output signal that is capable of stimulating cardiac tissue when a signal at the corresponding tuned frequency arrives at the receiver. An AM transmitter can activate any given one of the receivers by transmitting a signal into the subject's body at the proper frequency. A controller controls the transmitter by commanding the transmitter to transmit pulses of AC at different frequencies at different times, so that when those pulses are received by the correspondingly-tuned receivers, each of the receivers will generate respective output signals that stimulate respective parts of the heart at respective times to promote improved cardiac performance.

Implantable medical devices have modular lead bores that are constructed from individual lead bore modules. A given modular lead bore utilizes the number of individual lead bore modules necessary for the particular implantable medical device. Each lead bore module has a lead bore passageway and a feedthrough passageway. An electrical contact is present within the lead bore passageway of each lead bore module and the electrical contact is aligned to the lead bore passageway of a lead bore module. Hermetic feedthrough assemblies are also present within the lead bore passageway of each lead bore module. A feedthrough pin passes through a hermetic feedthrough assembly within a feedthrough passageway of each lead bore module. Each feedthrough pin is electrically coupled to a corresponding electrical contact and the medical device circuitry.

A low-profile cranial device is adapted for covering and protecting electrical leads. The cranial device includes a static cranial implant shaped and dimensioned for housing a functional neurosurgical implant including electrical leads. The static cranial implant includes an outer first surface along an exterior side of the static cranial implant, an inner second surface along an interior side of the static cranial implant, and a peripheral wall extending between the outer first surface and the inner second surface. A cavity is formed along the outer first surface of the static cranial implant, the cavity being shaped and dimensioned to house the functional neurosurgical implant in a manner allowing the electrical leads to be wound up to store excess electrical lead length.

The present disclosure provides advantageous post and partition assembly that is configured and adapted to promote modularity and withstand the harsh environment of central sterile processing processes. Modular post assembly may be removed and relocated on tray without additional fasteners or components. Tray and bracket assembly may further provide identification features to correctly associate cataloged reusable medical devices to identified trays.

Provided herein is method of modulating a plurality of neurons in a patient, by stimulating an area of the patient's central nervous system. The stimulation includes alternating first periods when a plurality of pulses of electrical stimulation are delivered and second periods when no pulses of electrical stimulation are delivered. The first periods have a duration of about 100 to about 400 ms and the second periods have a duration of about 500 ms to about 1900 ms. The pulses have a frequency of about 100 Hz to about 250 Hz.

A universal low-profile intercranial assembly includes a mounting plate and a low profile intercranial device composed of a static cranial implant and an interdigitating functional neurosurgical implant. The low profile intercranial device is shaped and dimensioned for mounted to the mounting plate.

A method for minimally invasive deep brain simulation (DBS) involves obtaining a target location for the DBS, obtaining an anatomical model, and simulatively determining, for a set of antennas endocranially implanted at first positions and emitting electromagnetic waves differing by a frequency offset, a first envelope signal at the target location, using the anatomical model. The first envelope signal resulting from interference of the electromagnetic waves at the target location has an envelope signal frequency corresponding to the frequency offset.

A system includes spatially isolated nodes proximal to a cortical surface or spinal cord, a telemetric antenna array located above the dura, the telemetric antenna array configured to provide power to and exchange data with the spatially isolated nodes, and a power and data distribution unit configured to power the spatially isolated nodes, aggregate recorded data, send the aggregated recorded data and commands through a wireless link.

A method for subcutaneously treating pain in a patient includes first providing a neurostimulator with an IPG body and at least a primary, a secondary, and a tertiary integral lead with electrodes disposed thereon. A primary incision is opened to expose the subcutaneous region below the dermis in a selected portion of the body. A pocket is then opened for the IPG through the primary incision and the integral leads are inserted through the primary incision and routed subcutaneously to desired nerve regions along desired paths. The IPG is disposed in the pocket through the primary incision. The primary incision is then closed and the IPG and the electrodes activated to provide localized stimulation to the desired nerve regions and at least three of the nerves associated therewith to achieve a desired pain reduction response from the patient.
