Publication number: 20220409883Abstract: Implantable medical systems that include an implantable medical lead coupled to an implantable medical device for purposes of electrical stimulation therapy and/or sensing of physiological signals includes at least one twisted pair of conductors within the implantable medical lead. The twisted pair corresponds to a stimulation or sensing channel of the implantable medical device. The twisted pair provides attenuation of electromagnetic interference noise that is present at the lead or lead extension. The twisted pair may be present in a lumen of the implantable medical lead or encapsulated by the lead body. The twisted pair, along with any other conductors of the lead, may be of a linear configuration or may be coiled.Type: ApplicationFiled: June 23, 2022Publication date: December 29, 2022Inventors: Brian J.

Patent number: 11394226Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue. In one example, a temperature sensor may sense a temperature of a portion of a device, wherein the portion is non-thermally coupled to the temperature sensor. A processor may then control charging of the rechargeable power source based on the sensed temperature.Type: GrantFiled: December 7, 2020Date of Patent: July 19, 2022Assignee: Medtronic, Inc.Inventors: Peng Cong, Venkat R.

Patent number: 7024246Abstract: Apparatus and method assure the electrical characteristics of a stimulation waveform to an electrode of an Implantable Neuro Stimulator. The embodiment comprises a regulator, a measurement module, a generator, and a processor. The generator provides an input signal to the regulator. The regulator consequently regulates the input signal in order to form a pulse that is applied to the electrode. The processor instructs the measurement module to perform an electrical measurement that is indicative of an amplitude of the pulse. If the electrical measurement is sufficiently different from a desired value, the processor instructs the generator to be reconfigured in order that the amplitude of the pulse is within an acceptable value. A redundant capacitor pair may be inserted in a capacitor arrangement in order to compensate for a reduced battery voltage, or a detected faulty component such as a capacitor or a regulator may be replaced with a redundant component.Type: GrantFiled: April 26, 2002Date of Patent: April 4, 2006Assignee: Medtronic, IncInventors: Carlos C. Acosta, Leroy L. Perz, Carleen J. Juran, Kevin L. Bright, Richard E. Hester
