Publication number: 20230181261Abstract: Disclosed are various examples and embodiments of systems, devices, components and methods configured to rehabilitate or strengthen one or more muscles in a patient, and to reduce pain sensed by the patient, through a unique combination of electrical stimulation signals delivered to one or more target peripheral nerves. Medical electrical lead(s) comprising electrode(s) are positioned adjacent to, in contact with, or in operative positional relationship to, one or more target peripheral nerves of the patient. The target peripheral nerves typically comprise motor and sensory nerves. In one embodiment, first stimulation signals having a first range of frequencies are delivered through the electrode(s) to the target nerves to rehabilitate muscles enervated by the motor nerves. Second stimulation signals having a second range of frequencies are delivered through the electrode(s) to the target nerves to provide pain relief to the patient.Type: ApplicationFiled: October 26, 2022Publication date: June 15, 2023Inventors: Lee Stylos, Jeffrey Gagnon, John Swoyer, Scott Drees

Patent number: 8055335Abstract: Adaptations to an intra-thoracic fluid-status-trend indication and/or alert algorithm are disclosed. Some embodiments monitor fluid levels in heart failure patients and others suffering from pulmonary edema and the like. Some embodiments reset a cumulative fluid index when a short-term intra-thoracic impedance value exceeds a baseline impedance value minus a predetermined positive hysteresis value. Many device, system, and method embodiments hereof serve to reduce the number of false positive alerts while retaining the desired sensitivity.Type: GrantFiled: July 28, 2006Date of Patent: November 8, 2011Assignee: Medtronic, Inc.Inventor: Lee Stylos

Patent number: 7996084Abstract: An implantable medical device (IMD) performs periodic testing of a patient to determine ischemia threshold information. At selected times while the patient is at rest, the IMD increases the pacing rate over time until it receives feedback either from the patient or from an ischemia sensor. The IMD determines the threshold based upon the pacing rate at the time when the feedback was received. The threshold information can be used to adjust the upper pacing rate that can be used during rate adaptive pacing, to determine the effects of drug therapy, and to provide a general indication of the state of coronary artery disease in the patient. The periodic increase of pacing rate to the ischemic zone also provides a preconditioning of the myocardium to allow the patient greater exercise benefit without angina.Type: GrantFiled: April 19, 2006Date of Patent: August 9, 2011Assignee: Medtronic, Inc.Inventors: Lee Stylos, Todd J. Sheldon, Steven N. Lu, William J. Combs, Robert J. Nehls

Patent number: 7181268Abstract: Techniques for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanical activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart that are sensed by an accelerometer sensor. The heart acceleration signal can be obtained from an single- or multiple-axis accelerometer and/or a pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes to increase the reliability of ischemia detection.Type: GrantFiled: November 25, 2002Date of Patent: February 20, 2007Assignee: Medtronic, Inc.Inventors: Todd J.
