CHECKPOINT

NERVE STIMULATOR / LOCATOR

Checkpoint Surgical’s nerve stimulation devices inform intraoperative decision making to help surgeons safely and effectively protect, assess and repair motor nerves during surgeries.

The Checkpoint Nerve Stimulator provides visual confirmation of nerve function and location in the surgical field, even in obscured anatomy. All Checkpoint stimulators may be used safely for sustained or repeated nerve stimulation without diminished response.

MAPPING

Reliably locate nerves in altered anatomy or anytime nerves are at risk
Map location of nerve through tissue
Localize nerve tissue obscured by scarring, tumor or bone

ASSESSMENT

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

Confirm whether a tissue structure is a nerve
Confirm with full tetanic contraction (vs a “twitch”)
Identify individual fascicle groups within a nerve

NERVE SAFE BIPHASIC TECHNOLOGY

All Checkpoint Stimulators use a biphasic waveform that is safe for prolonged or repeated stimulation without diminished response.
