Abstract: A method of producing an electrode brain probe assembly, using a flexible substrate comprising a polymeric layer bearing a conductive material coating. Photolithography and electroplating are used to form a set of contacts and conductors on the polymeric layer of the flexible substrate. Also, the flexible substrate is shaped to have a distal end and to be at least 5 mm long, but less than 5 mm wide and less than 1 mm thick.
Abstract: A system, method, and computer program product for calibrating a stimulation device such as an implantable pulse generator (IPG). An IPG, whether it is a self-contained implantable pulse generator (SCIPG) or externally-powered implantable pulse generator (EPIPG), communicates with an external programmer to determine the characteristics of the stimuli delivered to the lead electrodes. An external programmer is used with patient feedback to determine initial threshold levels, and using the initial threshold levels, to determine threshold levels for combined electrode arrays.

Abstract: An electronic stimulation system is used to control pain over multiple regions of a patient's body. The system has one or more percutaneous leads, each having multiple electrodes, implanted within the patient's epidural space parallel to the axis of the spinal cord. The leads are connected to either a totally implanted system or a radio frequency system. The system is able to treat pain over different regions of a patient's body by “simultaneously” stimulating the patient with at least three different stimulation settings. “Simultaneous” stimulation involves sequentially stimulating the patient with the multiple stimulation settings such that the patient receives the cumulative effect of each stimulation setting, while not perceiving the transition from one stimulation setting to another.

Abstract: The invention relates to a stimulation device for creating complex or multi-purpose tissue stimulation. Many typical stimulation devices suffer from deficiencies in providing complex stimulation patterns. Using a circuitry operable or programmable to repeat and skip stimulation settings, a complex stimulation set may be created. The repeating and skipping functionality may be implemented in hardware or software. In this manner, complex stimulations may be derived from simple circuitries. Furthermore, these stimulations may be used to treat pain, stimulate bone growth, and control motor disorders, among others.
Abstract: A wireless communication method and protocol, and wireless devices and systems for stimulation, are provided for communication between a wireless device and a charging device. During active wireless charging, communications (data transmission) from the wireless device to the charging device occurs via pulse loading the receive antenna of the receiving device. Because switching regulation in the receiving device may interfere with the communications, the switching regulation is disabled during a communications window. To further reduce the likelihood of misinterpretation of signals detected in the charging device resulting from the switching regulation or noise, the data bit rate of the pulse loading communications is maintained higher than the switching regulation frequency.

Abstract: The invention is directed to an implantable pump. The implantable pump has a port with light emitters indicating the location of the port. The port can be useful in providing bolus injections or the refilling of reservoirs. The light emitters can be arranged in various forms about the port including linear, triangular, square, or circular, among others. If more than one port is located on a device, these ports can be differentiated by differing colors and arrangements of emitters. In addition, various circuitries can be used to activate the emitters. These circuitries can include a coil and capacitor arrangement that provide a separate power source from that of the pump.
Abstract: A bio-probe having a base and a tip, and comprising a longitudinal core of substantially rigid material. On the core, there is a first layer of dielectric material, supported by and substantially circumferentially surrounding the core. Also, a set of conductors, each conductor extending longitudinally along the first layer of dielectric material and a second layer of dielectric material, substantially covering each of the set of conductors. For each of the conductors, an aperture is defined through the second layer of dielectric material to the conductor, thereby defining an electrode. In one preferred embodiment of this aspect, the first layer of insulative material is in the form of a tube and wherein the core is removable from the tube.

Abstract: A system, method, and implantable pulse generator (IPG) device that stores, on the implantable device, two or more treatment-protocol stimulus programs, each preferably having one or more stimsets, preferably as prescribed by a physician. The IPG communicates with an external patient programmer (EPP) to determine which of the stimulus programs should be run at any given time. Programs stored on the IPG are uploaded to the external device, and a selected program retransmitted (either the program itself, or selection information identifying the selected one of the IPG-stored programs) to the IPG for execution. An advanced programmer is used to read and write program instructions to the IPG. In this way, the patient is capable of carrying two or more program options with him, and if the patient uses an EPIPG, he can use any available EPP to power and operate the EPIPG.
