5 results about "Stimulation rate" patented technology

An implantable medical device is configured to determine a value of a monitored variable by the implantable medical device and convert the value to a data sequence of modulated electrical stimulation rate intervals. The implantable medical device delivers electrical stimulation pulses according to the data sequence of modulated stimulation rate intervals to produce a modulated activation rate of excitable tissue of a patient corresponding to the modulated stimulation rate intervals. The modulated activation rate is detectable by a rate monitor to demodulate the value of the monitored variable data. In some examples, the implantable medical device is a pacemaker that delivers cardiac pacing pulses according to modulated pacing rate intervals to produce a modulated heart rate of the patient that is detectable by a heart rate monitor to demodulate the value of the monitored variable.

Methods and systems for providing deep brain stimulation (DBS) for a patient are described. Electrical stimulation is provided to a patient's brain and evoked potentials (EPs) are recorded at two or more electrodes. The EPs evoked and / or recorded at different electrodes are used to estimate if the respective electrodes are located in the same or different anatomical brain regions. The EPs may also be used to predict or suggest appropriate stimulation rates for therapeutic stimulation.

A system for cardiac electrical stimulation therapy includes an implantable pulse generator, one or more leads extending from the implantable pulse generator to the heart for applying cardiac electrical stimulation, and a controller programmed with at least one therapy program for applying the cardiac electrical stimulation, the controller configured to automatically update the therapy program in response to actual cardiac activity by updating one or more parameters including a time period for applying cardiac electrical stimulation, a cardiac electrical stimulation rate, an amount of energy delivered per cardiac electrical stimulation.

A sleep induction device, wherein the control unit reads a stimulation rate that is associated with a stimulation part from a storage unit, calculates a stimulation candidate by making a shift in the stimulation rate by a predetermined amount, outputs a drive signal according to the stimulation candidate, acquires a detection time from start of output of the drive signal to detection of sleep onset by the sensor, and causes the storage unit to store the stimulation candidate and the detection time as the stimulation rate and a sleep induction time, in association with the stimulation part, when the detection time is shorter than the sleep induction time.
