Deficiencies of Existing Solutions
MAXIMAL EXSANGUINATION IS NEEDED TO PREVENT
PULMONARY & CEREBRAL EMBOLIZATION.
Partial exsanguination is inherent in the traditional
Esmarch/PneumaticTourniquet method.
RISKS OF INCOMPLETE EXSANGUINATION (<67%):
- Pulmonary Emboli (PE):
- Blood left behind results in clots and
- intravascular clotting and often
- occurs during surgery where a tourniquet is used.
- When the tourniquet is deflated, blood clots migrate
- to the heart and lungs, leading to risk of brain
- infarcts, e.g. post TKA Cognitive Dysfunction.
- Near perfect exsanguination by NEO-T largely prevents
- embolization.
Cerebral Emboli & Infarction:
- Small emboli block small arteries,
- reducing or preventing blood flow
- to brain regions, followed by small infarctions,
- resulting mostly in cognitive dysfunction.

- Total Knee Arthroplasty.
- Lancet. 1993 Apr 24;341(8852):1057-8)
- Post operative side effects: Risk of post-op DVT, skin injury
- tourniquet burn (20.7%),
- tourniquet pain (39.7%), and nerve damage.
STERILITY ISSUES: Increased risk of Surgical Site Infection (SSI).
Non-Sterile Pneumatic Tourniquets are Contaminated
A Potential Cause of SSI.
Sterile NEO-T is 100% safe.
REDUCED ACCESSIBILITY – WIDE CUFF: Reduced access,
especially in obese limb or pediatric
cases and limited anatomical visibility during surgery
SIDE EFFECTS DUE TO PRESSURE ON TISSUES:
Traditional wide cuffs produce increased uniform
pressure inside the limb vs. the NEO-T narrow cuff where axial and radial
pressure gradients result in less force on inner tissue.
INEFFICIENCIES: Increased preparation and setup time
less procedures, high cost derivative, and OR clutter.
- Time wasted: Traditional methods require
- 12 minutes of patient setup time
- vs. 15 seconds with NEO-T application
- Inefficiency and aggregate cost of multiple products
- used during a procedure that employs the pneumatic
- tourniquet vs. the single-use sterile NEO-T device.
- OR clutter and shelf space incurred by the pneumatic
- tourniquet method is eliminated by NEO-T
