Abstract
Techniques for therapy delivery are described. A processing circuit may adjust a first therapy parameter from a first level to a second level, and responsive to the adjustment of the first therapy parameter, compare a level of an evoked compound action potential (ECAP) generated from therapy delivery based on the adjusted first therapy parameter to an ECAP threshold. The processing circuit may adjust a second therapy parameter from a third level to a fourth level based on the comparison. The second therapy parameter is different than the first therapy parameter. The processing circuit may cause therapy delivery with the first therapy parameter at the second level and the second therapy parameter at the fourth level.
Claims40
A method of therapy delivery, the method comprising:
- adjusting a first therapy parameter from a first level to a second level different than the first level;
- responsive to the adjustment of the first therapy parameter, comparing a level of an evoked compound action potential (ECAP) generated in response to therapy delivered with the adjusted first therapy parameter to an ECAP threshold;
- adjusting a second therapy parameter from a third level to a fourth level different than the third level based on the comparison, wherein the second therapy parameter is different than the first therapy parameter;
- and
- causing delivery of the therapy with the first therapy parameter at the second level and the second therapy parameter at the fourth level.
A device for therapy delivery, the device comprising:
- a stimulation circuit;
- and
- a processing circuit configured to:
- adjust a first therapy parameter from a first level to a second level different than the first level;
- responsive to the adjustment of the first therapy parameter, compare a level of an evoked compound action potential (ECAP) generated in response to therapy delivered with the adjusted first therapy parameter to an ECAP threshold;
- adjust a second therapy parameter from a third level to a fourth level different than the third level based on the comparison, wherein the second therapy parameter is different than the first therapy parameter;
- and
- cause the stimulation circuit to deliver therapy with the first therapy parameter at the second level and the second therapy parameter at the fourth level.
A computer-readable storage medium storing instructions thereon that when executed cause one or more processors of a device for therapy delivery to:
- adjust a first therapy parameter from a first level to a second level different than the first level;
- responsive to the adjustment of the first therapy parameter, compare a level of an evoked compound action potential (ECAP) generated in response to therapy delivered with the adjusted first therapy parameter to an ECAP threshold;
- adjust a second therapy parameter from a third level to a fourth level different than the third level based on the comparison, wherein the second therapy parameter is different than the first therapy parameter;
- and
- cause delivery of the therapy with the first therapy parameter at the second level and the second therapy parameter at the fourth level.
A device for therapy delivery, the device comprising:
- means for adjusting a first therapy parameter from a first level to a second level different than the first level;
- responsive to the adjustment of the first therapy parameter, means for comparing a level of an evoked compound action potential (ECAP) generated in response to therapy delivered with the adjusted first therapy parameter to an ECAP threshold;
- means for adjusting a second therapy parameter from a third level to a fourth level different than the third level based on the comparison, wherein the second therapy parameter is different than the first therapy parameter;
- and
- means for causing delivery of the therapy with the first therapy parameter at the second level and the second therapy parameter at the fourth level.
A system for therapy delivery, the system comprising:
- an implantable medical device (IMD) comprising a stimulation circuit;
- one or more leads coupled to the IMD;
- and
- a processing circuit configured to:
- adjust a first therapy parameter from a first level to a second level different than the first level;
- responsive to the adjustment of the first therapy parameter, compare a level of an evoked compound action potential (ECAP), sensed via at least one of the one or more leads, generated in response to therapy delivered with the adjusted first therapy parameter to an ECAP threshold;
- adjust a second therapy parameter from a third level to a fourth level different than the third level based on the comparison, wherein the second therapy parameter is different than the first therapy parameter;
- and
- cause the stimulation circuit to deliver therapy with the first therapy parameter at the second level and the second therapy parameter at the fourth level via at least one of the one or more leads.
