Publication number: 20240226558Abstract: Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain.Type: ApplicationFiled: March 21, 2024Publication date: July 11, 2024Inventors: Que T.

Publication number: 20240226561Abstract: Methods and systems for assisting a patient to reprogram parameters of an implantable medical device, such as a spinal cord stimulator, are disclosed. A patient may use an external controller, which may be either a dedicated device or a personal computing device, to interact with their implantable medical device and evaluate the efficacy of their therapy. If the efficacy diminishes, the patient may use their external controller to adjust either the neural dosage (i.e., frequency, pulse width, and/or amplitude) and/or the location at which stimulation is provided. A reprogramming assistant is provided, which guides the patient in adjusting their stimulation using their external controller. The patient may use supra-perception or sub-perception stimulation for the adjustment. The implantable medical device may include pre-programmed “rescue programs” to assist the patient in recovering the efficacy of their therapy.Type: ApplicationFiled: March 20, 2024Publication date: July 11, 2024Inventors: Ismael Huertas Fernandez, Que T.

Further, a user interface element is provided to allow a user to automatically step thought suitable duty cycle values determined to be appropriate for the stimulation parameters. As such, the user does need not need to engage in guess work to specify individual on and off times when duty cycling is desired.Type: ApplicationFiled: April 10, 2023Publication date: November 9, 2023Inventors: Ismael Huertas Fernandez, Que T.

Publication number: 20230128146Abstract: Techniques are disclosed for adjusting sub-perception stimulation applied to a patient by an Implantable Pulse Generator (IPG).
