Publication number: 20220273949Abstract: In some examples, a medical device is configured to deliver high dose electrical stimulation therapy to a patient by at least generating and delivering an electrical stimulation signal having a relatively high duty cycle, and a stimulation intensity less than a perception or paresthesia threshold intensity level for the patient. The pulses of the electrical stimulation signal may each have a relatively low amplitude, but due at least in part to a relatively high number of pulses per unit of time, a dose of the electrical stimulation may be high enough to elicit a therapeutic response from the patient.Type: ApplicationFiled: May 16, 2022Publication date: September 1, 2022Inventor: Lisa M. Johanek

Patent number: 11383086Abstract: In some examples, a medical device is configured to automatically determine a paresthesia threshold or a perception threshold of a patient in a second posture based on the paresthesia threshold or perception threshold of that patient in a first posture. The medical device may deliver an electrical stimulation signal to a patient and determine the paresthesia threshold or perception threshold for the patient in the first posture. The medical device may change the intensity of the electrical signal and receive an indication from the patient that they are experiencing paresthesia or perceiving the electrical stimulation signal. The medical device may then automatically determine a predicted paresthesia threshold or predicted perception threshold for a second posture based on the paresthesia threshold or perception threshold.Type: GrantFiled: February 21, 2020Date of Patent: July 12, 2022Assignee: Medtronic, Inc.Inventors: Lachlan Davies, Sheryl McCammon, Andrew J. Cleland, Melanie D Goodman Keiser, Ye Tan, Lisa M. Johanek, Nathan A. Torgerson

Patent number: 11311729Abstract: In some examples, a medical device is configured to deliver sub-threshold electrical stimulation therapy to a patient at a stimulation intensity that is significantly less than a perception or paresthesia threshold intensity level for the patient. The medical device may determine the particular intensity level for the patient through a titration process. The medical device may titrate automatically or based upon the input of the patient, a clinician or a physician.Type: GrantFiled: February 21, 2020Date of Patent: April 26, 2022Assignee: Medtronic, Inc.Inventors: Lachlan Davies, Sheryl McCammon, Andrew J.
