Patent number: 11969592Abstract: An implantable medical device (IMD) includes a memory configured to store a set of therapy parameters for subsensory electrical stimulation of a patient; and therapy delivery circuitry configured to deliver the subsensory electrical stimulation to at least one of a sacral nerve or tibial nerve based on the stored set of therapy parameters to provide immediate therapeutic effect caused by the ongoing delivery of the subsensory electrical stimulation to address incontinence, wherein a stimulation intensity of the subsensory electrical stimulation is less than 80% of a stimulation intensity at a sensory threshold, and wherein the patient does not perceive delivery of the subsensory electrical stimulation and perceives delivery of stimulation at the sensory threshold.Type: GrantFiled: March 30, 2023Date of Patent: April 30, 2024Assignee: Medtronic, Inc.Inventors: Lance Zirpel, Sudha B. Iyer, Xuan K. Wei

Patent number: 11638821Abstract: The disclosure describes example of subsensory electrical stimulation for providing therapy for incontinence. An implantable medical device (IMD) includes a memory configured to store a set of therapy parameters for subsensory electrical stimulation of a patient. The delivery of the subsensory electrical stimulation results in a therapeutic effect for incontinence therapy at a stimulation intensity that is in range of approximately 50% to 80% of a stimulation intensity at a sensory threshold, and the patient does not perceive delivery of the subsensory electrical stimulation and perceives delivery of stimulation at the sensory threshold. The IMD also includes therapy delivery circuitry configured to deliver the subsensory electrical stimulation based on the stored set of therapy parameters, including cycling the delivery of the subsensory electrical stimulation between an on-cycle and an off-cycle.Type: GrantFiled: July 29, 2020Date of Patent: May 2, 2023Assignee: MEDTRONIC, INC.Inventors: Lance Zirpel, Sudha B. Iyer, Xuan K. Wei

Publication number: 20210299442Abstract: In some examples, a technique for delivering electrical stimulation therapy to a patient includes determining, by processing circuitry, one or more cycle settings associated with delivery of the electrical stimulation therapy, determining, by the processing circuitry, a cycle time period associated with each cycle setting, and delivering, by a medical device, electrical stimulation therapy based on the determined cycle settings and the determined cycle time periods. Each cycle setting may define an on-cycle, during which electrical stimulation is delivered, and an off-cycle, during which electrical stimulation is not delivered. The technique further may include delivering electrical stimulation to the patient to provide one or more reminders to the patient, such as a reminder to void or a reminder of the existence of electrical stimulation.Type: ApplicationFiled: June 10, 2021Publication date: September 30, 2021Inventors: Xuan K. Wei, Ryan D. Willemsen, Dwight E. Nelson, Sudha B. Iyer, Kira Stolen, Xin Su
