Constant Current Stimulation

Constant current can overcome impedance changes, such as scar tissue formation around the implanted lead, to continue to provide consistent stimulation over time. Axonics SNM Systems deliver constant current stimulation to help maintain the right amount of therapy and reduce the need for patients to make adjustments.2

External Trial System

  • Discreet and disposable
  • Supports basic and advanced trials
  • Programmable to same ranges of stimulation parameters as INS
