What Surgeons are Saying about Checkpoint

Designed by a team of surgeons and biomedical engineers, the CHECKPOINT® Stimulator/ Locator helps surgeons make better “real time” intra-operative decisions with increased confidence.

Michael R. Hausman, MD

"CHECKPOINT’s reliable and reproducible stimulation has helped not only to identify and protect nerves from injury, but also has proven very useful in nerve reconstruction cases."

* Lippmann Professor of Orthopedic Surgery, Vice-Chairman, Department of Orthopedic Surgery, Chief, Hand and Elbow Surgery, Mount Sinai Medical Center (NY)

"CHECKPOINT® has quickly become an essential part of my surgical tool-kit and is indispensable for my brachial plexus and other nerve repair cases."

* Professor, Orthopaedic Surgery, Temple University and Hand & Upper Extremity Surgeon, Shriners Hospitals for Children
Scott Kozin, MD
Evan Flatow, MD

"CHECKPOINT® has become an essential tool for my complex shoulder surgery cases, not only to help identify and protect nerves from injury, but also to gauge how well they are functioning."

Lasker Professor and Chair, Chief of Shoulder Surgery, Leni & Peter W. May Department of Orthopaedic Surgery, Mount Sinai Medical Center (NY)

"Finally, a well-designed disposable stimulation device that puts precision and control in the surgeon’s hand – a must for every peripheral nerve surgeon."

Assistant Professor of Neurological Surgery, Director of Peripheral Nerve Surgery at University of California, San Diego; Co-Director at Center for Neurophysiology and Restorative Neurology
Justin Brown, MD

* Dr. Hausman and Dr. Kozin are paid consultants and have a financial interest in Checkpoint Surgical

Training Videos

Reviewing the videos below will provide a good orientation to the use of Checkpoint in several surgical scenarios. For those of you unfamiliar with Checkpoint we would suggest you first watch “Checkpoint Commentary” by the internationally recognized Hand Surgeon Dr Scott Kozin before watching the “Checkpoint Comprehensive Instructional Video” to give you a better Surgeon-centric view of Checkpoint’s capabilities.

If you wish to watch the video elements separately we have broken the longer, comprehensive training video into
five smaller sections so you can watch just the portion of the material you are interested in reviewing.

Indications & Risk of the Checkpoint Stimulator & Locator

The Checkpoint® Stimulator is a single-use, sterile device intended to provide electrical stimulation of exposed motor nerve or muscle tissue to locate and identify nerves and to test nerve and muscle excitability.

INDICATIONS FOR USE:

The CHECKPOINT® Stimulator is a single-use, sterile device intended to provide electrical stimulation of exposed motor nerves or muscle tissue to locate and identify nerves and to test nerve and muscle excitability.

CONTRAINDICATION:

Do NOT use this Stimulator when paralyzing anesthetic agents are in effect, as an absent or inconsistent response to stimulation may result in inaccurate assessment of nerve and muscle function.

WARNINGS:
Indications-Chest-HN
  • Do NOT apply stimulation across the patient’s chest because the introduction of electrical current into the chest may cause rhythm disturbances to the patient’s heart.
  • Do NOT leave Stimulator unattended in the surgical field.
  • Do NOT use Stimulator in the presence of flammable anesthetics.
  • Do NOT use this Stimulator in patients with implanted electronic devices. Stimulus current near such devices may cause them to malfunction.
  • Do NOT use in cerebrospinal fluid, brain, meninges, or spinal cord.
  • Do NOT use the Stimulator while delivering electrocautery. Electrocautery may interfere with or damage the Checkpoint Stimulator or cause injury.
  • Use of a tourniquet may reduce nerve and muscle excitability distal to the tourniquet. If a decrease in nerve or muscle response to stimulation is observed, it may be necessary to take down the tourniquet and allow time for re-perfusion before testing with Checkpoint.
PRECAUTIONS:
  • Single use only. Once turned ON, the Stimulator will not turn OFF and will remain operational for approximately four (7) hours.
  • Use the Stimulator at 0.5mA initially and increase the amplitude as needed.
  • Do NOT bend the probe or apply excessive pressure where the probe enters the nose cone. Do NOT use the Checkpoint Stimulator as a dissecting tool or for any other purpose not specified in these Instructions for Use.
  • The needle return electrode may cause stimulation. Place the needle return electrode in an area away from excitable tissue and away from the stimulation area to avoid confusion.
  • Do NOT submerge or saturate the Checkpoint Stimulator with fluid.
  • The Stimulator may interfere with patient monitoring equipment in the operating room while stimulating.
  • Portable and mobile Radio Frequency (RF) communications equipment can interfere with the Stimulator. Do not use such equipment while delivering stimulation.
  • The Stimulator is not likely to cause any interference in nearby electronic equipment through Electromagnetic Interference (EMI) (complies with CISPR 11, Type B). For additional information on Electromagnetic Interference contact NDI Medical.
  • Be aware that using the device in the vicinity of certain nerves can have systemic effects (e.g. bradycardia, hypotension, laryngospasm).


The Checkpoint Stimulator is an adjunctive tool for locating nerves and testing nerve and muscle excitability. It is not intended to replace good surgical techniques in locating and dissecting tissue. The surgeon is ultimately responsible for identifying exposed motor nerves and tissue.
