Patent number: 11975187Abstract: Techniques are disclosed for delivering electrical stimulation therapy to a patient. In one example, a medical system delivers electrical stimulation therapy to a tissue of the patient via electrodes. The medical system determines a first change of a first sensed signal of the patient to movement by the patient and a second change of a second sensed signal of the patient to the movement by the patient. Based on the first change and the second change, the medical system selects one of the first sensed signal and the second sensed signal of the patient for controlling the electrical stimulation therapy. The medical system adjusts a level of at least one parameter of the electrical stimulation therapy based on the selected one of the first sensed signal and the second sensed signal.Type: GrantFiled: November 13, 2020Date of Patent: May 7, 2024Assignee: Medtronic, Inc.Inventors: Scott R. Stanslaski, Timothy R. Abraham, Thomas Adamski, Timothy J. Denison, Robert S. Raike

Publication number: 20240009465Abstract: Systems and methods that automatically adjust, or adapt, stimulation waveforms delivered to brain structures. Closed loop system embodiments can automatically be re-configured into a more suitable closed loop control system in response to measures of control system performance. Measures can be internal performance characteristics of the adaptive control system or external inputs provided by another subsystem. As these measures change in time, the robust adaptive system changes in response.Type: ApplicationFiled: September 26, 2023Publication date: January 11, 2024Inventors: Thomas L. Chouinard, Scott R. Stanslaski, Timothy R. Abraham, Robert S. Raike

Patent number: 11571576Abstract: Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed.Type: GrantFiled: December 31, 2020Date of Patent: February 7, 2023Assignee: Medtronic, Inc.Inventors: Evan D.

Patent number: 11458306Abstract: A shield located within an implantable medical lead may be terminated in various ways. The shield may be terminated by butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. For lap joints, a portion of an outer insulation layer may be removed and a replacement outer insulation layer is positioned in place of the removed outer insulation layer, where the replacement layer extends beyond an inner insulation layer and the shield. The replacement layer may also lap onto a portion of the insulation extension. The barbs may be located between the replacement layer and the inner insulation layer or the insulation extension. The shield wires have ends at the termination point that may be folded over individually or may be capped with a ring located within one of the insulation layers of the jacket.Type: GrantFiled: September 28, 2018Date of Patent: October 4, 2022Assignee: MEDTRONIC, INC.Inventors: Michael J. Kern, James M. Olsen, Michael R. Klardie, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham, Brian T. Stolz

Publication number: 20220143400Abstract: A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.Type: ApplicationFiled: December 14, 2021Publication date: May 12, 2022Inventors: Bruce R. Mehdizadeh, Brian T. Stolz, Michael Robert Klardie, James M. Olsen, Michael J. Kern, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham

Publication number: 20220062640Abstract: Devices, systems, and techniques for identifying electrodes closest to a target region of tissue are described. In one example, a device includes sensing circuitry configured to sense electrical signals from a plurality of electrode combinations. Processing circuitry identifies a first electrode combination of a first subset of electrode combinations. Each electrode combination of the first subset of electrode combination includes electrodes located at different axial positions along a length of the medical lead. The processing circuitry identifies a second electrode combination of a second subset of electrode combinations. Each electrode combination of the second subset of electrode combinations includes electrodes located at a same axial position and different circumferential positions around a perimeter of the medical lead. The processing circuitry then determines a third electrode combination and controls delivery of electrical stimulation via the third electrode combination.Type: ApplicationFiled: August 31, 2021Publication date: March 3, 2022Inventors: Robert S. Raike, Jadin C. Jackson, Scott R. Stanslaski, Eric J. Panken, Christopher L. Pulliam, Timothy R. Abraham, Michelle A. Case, Paula Andrea Elma Dassbach Green, Abbey Beuning Holt Becker, Rene A. Molina

Patent number: 11260222Abstract: Radiopaque markers represent that a lead is suitable for a particular medical procedure such as a magnetic resonance image scan and are added to the lead or related device. The markers may be added after implantation of the lead in various ways including suturing, gluing, crimping, or clamping a radiopaque tag to the lead or to the device. The markers may be added by placing a radiopaque coil about the lead, and the radiopaque coil may radially contract against the lead to obtain a fixed position. The markers may be added by placing a polymer structure onto the lead where the polymer structure includes a radiopaque marker within it. The polymer structure may include a cylindrical aperture that contracts against the lead to fix the position of the polymer structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.Type: GrantFiled: December 19, 2019Date of Patent: March 1, 2022Assignee: MEDTRONIC, INC.Inventors: James M. Olsen, Michael R. Klardie, Richard T. Stone, Chad Q. Cai, Spencer Fodness-Bondhus, Mark J. Conroy, Timothy R. Abraham, Bruce R. Mehdizadeh, Michael J. Kern, Jay K. Lahti
