Sustained long-term seizure control with no chronic stimulation side effects

Backed by “Level 1” evidence including 8 year follow up

Prospective, multicenter clinical trial experience represents 256 patients with >1,800 implant years

73% median seizure reduction1 at year 8:*

  • 66% responder rate
  • 30% achieved ≥90% seizure reduction in most recent 3 months**
  • 29% had at least 1 period of ≥6 months without seizures

Favorable SUDEP rates***

As compared to:

  • Patients with medication-resistant epilepsy
  • Candidates for epilepsy surgery

Improvements in
neuropsychological profile

Statistically significant6 improvements in:

  • Naming (p<0.001)
  • Verbal Learning (p<0.03)
  • Visual Memory (p<0.03)
  • Executive Function (p<0.001)

Safety outcomes from
prospective clinical trials

  • No adverse cognitive effects6
  • No chronic stimulation side effects7
  • Rates of serious device-related adverse events comparable to that of deep brain stimulation for movement disorders8,9

*Combined trial outcomes include data from Feasibility, Pivotal (randomized, double-blind, controlled), and Long-Term Treatment (open label, prospective) Trials. Long-Term Treatment Trial was not powered to drive conclusions of clinical significance.

**Based on last observation carried forward analysis.

***Population includes 707 patients treated either as part of clinical trials or as part of clinical care following FDA approval.
