Publication number: 20230218904Abstract: An Implantable Pulse Generator (IPG) is disclosed that is capable of sensing a degree to which recruited neurons in a patient's tissue are firing synchronously, and of modifying a stimulation program to promote desynchronicity and to reduce paresthesia. An evoked compound action potential (ECAP) of the recruited neurons is sensed as a measure of synchronicity by at least one non-active electrode. An ECAP algorithm operable in the IPG assesses the shape of the ECAP and determines one or more ECAP shape parameters that indicate whether the recruited neurons are firing synchronously or desynchronously. If the shape parameters indicate significant synchronicity, the ECAP algorithm can adjust the stimulation program to promote desynchronous firing.Type: ApplicationFiled: March 7, 2023Publication date: July 13, 2023Inventors: Bradley L. Hershey, Changfang Zhu

Publication number: 20220226655Abstract: An external control device and method for programming an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition. Electrical modulation energy is conveyed to tissue of the patient in accordance with a series of modulation parameter sets. The patient perceives paresthesia in response to the conveyance of the electrical modulation energy to the tissue in accordance with at least one of the modulation parameter sets. One of the modulation parameter set(s) is identified based on the perceived paresthesia. Another modulation parameter set is derived from the identified modulation parameter set. Electrical modulation energy is conveyed to the tissue of the patient in accordance with the other modulation parameter set without causing the patient to perceive paresthesia. An external control device, neuromodulation system, and method of providing therapy to a patient.Type: ApplicationFiled: April 4, 2022Publication date: July 21, 2022Inventors: Dennis Allen Vansickle, Dongchul Lee, Sridhar Kothandaraman, Que T.

Patent number: 11311726Abstract: An external control device, neuromodulation system, and method of providing therapy to a patient using an implantable neuromodulator implanted within the patient. Electrical modulation energy is delivered from the neuromodulator to the patient in accordance with the pre-existing modulation program when in one of the super-threshold delivery mode and the sub-threshold delivery mode. Operation of the neuromodulator is switched to the other of the super-threshold delivery mode and the sub-threshold delivery mode. A new modulation program may be derived from a pre-existing modulation program, and the neuromodulator may deliver the electrical modulation energy to the patient in accordance with the pre-existing modulation program during the other of the super-threshold delivery mode and the sub-threshold delivery mode.Type: GrantFiled: February 14, 2019Date of Patent: April 26, 2022Assignee: Boston Scientific Neuromodulation CorporationInventors: Dennis Allen Vansickle, Dongchul Lee, Sridhar Kothandaraman, Que T.
