Checkpoint 9094

Checkpoint Stimulator Locator

The Checkpoint Stimulator/Locator is a hand-held, single use intra-operative nerve and muscle stimulator that helps surgeons locate, identify and evaluate motor nerve tissue and muscle function in complex surgical procedures that require careful tissue dissection or nerve exploration and repair. The Checkpoint Stimulator/Locator was engineered to provide useful intra-operative feedback regarding the location, identification and excitability of nerves and muscles for surgeons

Surgeons can enjoy the following advantages:

  • Biphasic waveform allows for safe, repeated stimulation without diminished response
  • Can map location of nerve through tissue
  • Can localize nerve tissue obscured by scarring, tumor and bone
  • Can determine stimulation threshold for motor response
  • Can evaluate for over-tensioning of nerve tissue
  • Can test for changes in nerve function throughout procedures
  • Can stimulate muscle to evaluate excursion in tendon and free muscle transfers
  • Can confirm whether a tissue structure is or is not a nerve
  • Can identify individual fascicle groups within a nerve
  • Is a surgeon-controlled, low cost disposable

The Checkpoint Stimulator/Locator has proven to be especially helpful for surgeons when used intraoperatively the following ways:


Reliably locate nerves in altered anatomy or any time nerves are at risk

Threshold Testing

Evaluate nerve and muscle function for surgical decision-making

Eliciting a Tetanic Contraction

Confidently identify motor nerves during surgical exposure
