Publication number: 20240001125Abstract: Example devices and techniques for improving signal quality of a sensed evoked response signal include processing circuitry communicatively coupled to stimulation generation circuitry and sensing circuitry. The processing circuitry is configured to control the stimulation generation circuitry to generate a stimulation signal and receive from the sensing circuitry the sensed evoked response signal. The processing circuitry is configured to determine that a characteristic value of at least one of the artifact or the sensed evoked response signal meets a threshold and automatically change, based on the determination that the characteristic value of the at least one of an artifact in the sensed evoked response signal or the sensed evoked response signal meets the threshold, at least one sensing parameter.Type: ApplicationFiled: June 26, 2023Publication date: January 4, 2024Inventors: Benjamin P.

Publication number: 20230321442Abstract: A system to provide flexible stimulation pattern definition, delivery, and control to dynamically adjust a therapy regimen for electrical stimulation therapy based on patient needs. Firmware in an electrical stimulation delivery device that executes the therapy regimen may be implemented as a “player” of a series of instructions for the received stimulation patterns. The system may include a wearable device or an implantable device. An external computing device configured to program the electrical stimulation delivery device may include a stimulation pattern construct collection from which a clinician can select, assemble, and modify waveforms, bursts, pattern, sensing or other event triggers etc. to create a therapy regimen. The external computing device may transmit software that defines the selected regimen to the electrical stimulation delivery device memory, where the device “plays” the instructions to deliver electrical stimulation according to the therapy regimen.Type: ApplicationFiled: March 3, 2023Publication date: October 12, 2023Inventors: Benjamin P. Isaacson, Brett M. Nelson, Duane L. Bourget, Nicholas D. Buse, Laura A. Skarie, David E. Linde

Publication number: 20230310841Abstract: Techniques are disclosed for defining a homeostatic window for controlling delivery of electrical stimulation therapy to a patient. In one example, a method includes generating and delivering electrical stimulation therapy to tissue of a patient via electrodes. Further, the method includes adjusting a level of a parameter of the electrical stimulation therapy such that a signal of the patient is not less than a lower bound and not greater than an upper bound. The lower bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce one or more symptoms of a disease while the patient was receiving medication for reduction of the one or more symptoms. Further, the upper bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce the one or more symptoms when the patient was not receiving the medication.Type: ApplicationFiled: June 5, 2023Publication date: October 5, 2023Inventors: Scott R. Stanslaski, Thomas Adamski, Duane L. Bourget, Timothy J. Denison, Benjamin P. Isaacson, Eric J. Panken, Jeffrey Herron

Patent number: 11291843Abstract: Devices, systems, and techniques are described for transitioning between different groups of electrical stimulation programs. For example, a system may control delivery of second electrical stimulation defined by one or more second programs of a second group of stimulation programs on a time-interleaved basis with first electrical stimulation defined by one or more first programs of the first group of stimulation programs. The system may change a first ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a first period of time to a second ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a second period of time.Type: GrantFiled: December 7, 2018Date of Patent: April 5, 2022Assignee: Medtronic, Inc.Inventors: Duane L.

Patent number: 9079039Abstract: This disclosure describes a state machine framework for programming closed-loop algorithms that control the delivery of therapy to a patient by an implantable medical device (IMD). The state machine framework may use one or more programmable state parameters to define at least part of a structure of a state machine that generates one or more therapy decisions based on one or more sensed states of the patient. The state machine framework may include a state machine runtime environment that executes on an IMD and that is configurable to implement a variety of different state machines depending on programmable state parameters that are received from an external device. The techniques of this disclosure may, in some cases, allow IMD developers and/or users to program, change, and/or download new closed-loop control policy algorithms during the lifespan of the IMD without requiring new firmware code to be downloaded onto the IMD.Type: GrantFiled: July 2, 2013Date of Patent: July 14, 2015Assignee: Medtronic, Inc.Inventors: David L.
