    Abstract: Systems, devices, and techniques are described for analyzing evoked compound action potential (ECAP) signals to determine an estimated neural threshold of a patient. In one example, a method includes controlling, by processing circuitry, delivery of a plurality of stimulation pulses to a patient, wherein each stimulation pulse of the plurality of stimulation pulses is at least partially defined by a different respective value of a stimulation parameter; receiving, by the processing circuitry, ECAP signal information, wherein the ECAP signal information comprises ECAP signals sensed by sensing circuitry and elicited by the plurality of stimulation pulses; determining, by the processing circuitry and based on the ECAP signal information, ECAP characteristic values for each of the ECAP signals elicited by the plurality' of stimulation pulses; and determining, by the processing circuitry and based on the ECAP characteristic values, an estimated neural threshold of the patient.

    Abstract: This disclosure is directed to devices, systems, and techniques for delivering various stimulation patterns. In some examples, a method includes generating, by stimulation generation circuitry, a first train of electrical stimulation pulses at a first frequency to a first target tissue, and generating, by the stimulation generation circuitry, a second train of electrical stimulation pulses at a second frequency to a second target tissue different from the first target tissue, wherein at least some electrical stimulation pulses of the first train of electrical stimulation pulses are interleaved with at least some electrical stimulation pulses of the second train of electrical stimulation pulses, and wherein the first frequency is greater than the second frequency.

    Abstract: Devices, systems, and techniques are configured for independently modulating two or more concurrent signals of electrical stimulation therapy. In one example, a system includes stimulation generation circuitry and processing circuitry configured to control the stimulation generation circuitry to deliver first electrical stimulation to a patient via a first electrode combination, wherein the first electrical stimulation is defined by at least a first set of stimulation parameters selected that the first electrical stimulation exceeds a first perception threshold, and control the stimulation generation circuitry to deliver second electrical stimulation, concurrent with the first electrical stimulation, to the patient via a second electrode combination. The second electrical stimulation may be defined by at least a second set of stimulation parameters selected that the second electrical stimulation is below a second perception threshold. The processing circuitry may also determine a triggering condition and independently modulate the first and/or second electrical stimulation.

    Abstract: Techniques to provide haptic feedback to a patient to help the patient align a medical device to a location on their anatomy. In some examples, the patient may align a recharging device to a medical device that is implanted at the location on their anatomy. In some examples, the electrical stimulation can be delivered in such a way that the patient may or may not be able to feel the electrical stimulation, e.g., experience a paresthesia sensation. The system of this disclosure may intentionally adjust the stimulation intensity to provide patient feedback for alignment, such as alignment of the recharging device with the implanted device. Alignment of the recharging device with the implanted device may improve energy transfer, which may, for example, recharge the implanted device more efficiently.
