EMIT LLC formed in June of 2018. Our focus is on medical device innovation and technology.  The President/CEO, has created a novel innovative airway device (The Mechanical Coupler Filter Endotracheal Tube, or MCFET) that will help reduce infection, and cross-contamination in the airway-compromised population (intubated patients or patients with a supraglottic airway device being manually or mechanically ventilated)  among other great and necessary benefits.  This novel device will help manage patient airways more effectively, and hopefully reduce high cost associated with these very sick individuals; one example being hospital cost due to increased rates of infection, prolonging a patients stay and costing them anywhere from $200k-$500k+ (and that cost is for a 2-3 week stay!).  

The cross-contamination implementation will help reduce the spread of droplet/airborne contaminants such as COVID-19, and other communicable diseases, something that Mr. cantor thought of years ago!  This novel device should have been in the market years ago, and now more than ever is the best time to get it into the market!
