Checkpoint

Nerve Stimulator & Locator Device

Immediate and reproducible visual confirmation of nerve function and location in the surgical field, even in obscured anatomy.

Nerve Stimulator & Locator

The Checkpoint nerve stimulator 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 nerve stimulator was engineered to provide useful intra-operative feedback regarding the location, identification and excitability of nerves and muscles for surgeons.

360 LED Indicator Light

Provides continuous visual confirmation that stimulus is being delivered to evaluate nerve function for surgical decision-making

Selective Amplitude Switch

Adjust threshold stimulus desired for precise, highly localized individual nerve stimulation to wide and deep generalized nerve activation

Pulse Width Slide Control

Continuously variable intensity at each amplitude to fine-tune stimulus parameters + built-in batteries eliminate need for cables

Over 400 (and 19 of the top 20)

Testimonials

Surgeons trust the Checkpoint 9094 because it empowers them to confidently & accurately identify motor nerves during surgical exposure

Dr. Michael R Hausman

"Nearly all surgeons inadvertently inflict a nerve injury at some point in their career. The question we ought to ask, prospectively, is, 'What can I do to avoid that problem?' Fortunately, there are precautions that can increase the margin of safety."

Dr. Scott H. Kozin

"The Checkpoint Nerve Stimulator provides a valuable tool during surgery. The stimulator is reliable and has variable parameters to directly assist in intraoperative decision-making. The device can safely stimulate the nerve either continuously or repeatedly without fear of diminishing the nerve and muscle response."

Protect, Assess & Confirm

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

Mapping

Mapping with the Checkpoint Nerve Stimulator allows surgeons to reliably locate nerves in altered anatomy or anytime nerves are at risk. With Checkpoint surgeons can safely do the following intraoperatively:

  • Map location of nerve through tissue
  • Localize nerve tissue obscured by scarring, tumor or bone

Threshold Testing

Threshold testing allows surgeons to evaluate nerve and muscle function for surgical decision-making by using Checkpoint to do the following:

  • Determine stimulation threshold for motor response
  • Test for changes in nerve function throughout the procedure
  • Stimulate muscle to evaluate excursion in tendon and free muscle transfers

Eliciting a Tetanic Contraction

Checkpoint’s biphasic waveform allows for continuous stimulation that can elicit a full tetanic contraction instead of simple “twitch” elicited by traditional direct current stimulators.

  • Confirms whether a tissue structure is or is not a nerve
  • Definitive confirmation (with full tetanic contraction)
  • Identifies individual fascicle groups within a nerve
