David A. Dinsmoor - Minneapolis MN, US
Warren L. Starkebaum - Plymouth MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/05
A61N 1/32

US Classification:

607 40

Abstract:

A gastro-electric stimulation system includes an INS for producing an electrical stimulation signal, at least one medical electrical lead, and at least two electrical contacts. The medical electrical lead has a proximal end and a distal end, the proximal end being connected to the INS and the distal end being adapted for placement in or near a patient's stomach or appropriate nerve or nerve portion. The electrodes are disposed near the distal end of the medical electrical lead, and the electrodes are electrically connected through the medical electrical lead to the INS to receive the electrical stimulation signal and convey such signal to the selected electrode implant position. The electrical stimulation signal is provided in an amount and manner adapted to decrease the pH of the gastric acid in the patient's stomach and/or to increase the amount of gastric acid produced thereby.

A61N 1/08

US Classification:

607 60, 607 34, 607 62

Abstract:

An integrated activation system for an implantable medical device (IMD) sharing a power source, the activation system comprising a switching circuit having first and second inputs and having an output coupled to the acute use device, a gating element coupled to the first input and configured to gate power from the power source to the switching circuit, and a sensing element coupled to the second input of the switching circuit. The sensing element is configured to sense an activation condition, enable an operation interval of the switching circuit, and transmit a signal to the switching circuit during the activation condition. The switching circuit is configured to transmit power to the acute use device upon receipt of a pre-determined number of signals from the sensing element.

Appl. No.:

17/807192

Inventors:

- Minneapolis MN, US
David A. Dinsmoor - North Oaks MN, US

International Classification:

A61N 1/36

Abstract:

Systems, devices, and techniques are described for adjusting a sensing window for sensing a feature of an evoked compound action potential (ECAP). In one example, a medical device includes processing circuitry configured to determine a value of a stimulation parameter that at least partially defines an electrical stimulation pulse and select, based on the value of the stimulation parameter, a sensing window for detecting one or more features of a sensed evoked compound action potential (ECAP) signal elicited by the electrical stimulation pulse. The processing circuitry can also determine a value of each of the one or more features within the sensing window from the sensed ECAP signal and control, based on the value of each of the one or more features, subsequent electrical stimulation deliverable to a patient.

A61N 1/372
A61N 1/36

Abstract:

Methods, systems, and devices for implantable node are described. The method may include storing, at an implantable stimulation node, a set of stimulation profiles in a memory during a configuration phase. The method may also include receiving a stimulation command corresponding to a stimulation profile of the set of stimulation profiles during a treatment phase. The method may further include delivering stimulation based at least in part on the stimulation profile corresponding to the received stimulation command. In some cases, the system may include an implantable hub, an implantable sensing node, and a sensing device.

Abstract:

Devices, systems, and techniques for controlling electrical stimulation therapy are described. In one example, a system is configured to deliver, via a first electrode combination, a first stimulation pulse to a portion of a spinal cord of a patient located caudally of a spinal cord injury location of the spinal cord of the patient; sense, via a second electrode combination, an evoked compound action potential (ECAP) signal elicited by the first stimulation pulse; identify, by processing circuitry, a characteristic of the ECAP signal; determine, by the processing circuitry and based on the characteristic of the ECAP signal, a therapy parameter value that at least partially defines a second stimulation pulse; and deliver the second stimulation pulse according to the determined therapy parameter value.
