"Traumatic PTX is a leading cause of preventable mortality in multi-trauma patients"

-  Lanny F. Littlejohn MD

Currently, there are no standardized, effective means to secure needle decompression catheters. This raises several pressing issues in the high-stress environments where needle decompressions must occur. 

A tension PTX can also result if the catheter becomes dislodged, kinked blocked..."

 - Inaba K Division of Trauma Surgery and Critical Care University of California

Although NDC placement at the anterior mid-axillary line avoids damage to vital organs and vasculature contained within the cardiac box, and takes advantage of decreased  chest wall thickness, usage of this site is currently overshadowed by the fact that natural patient arm movements immediately kink, occlude, or dislodge the catheter.


"NT dislodgement difficult to detect as the catheter may initially slide 'in and out' of the pleural space"

- D. Eiferman The American Surgeon 2011 Issue 77 

Common practice for failed needle decompression due to kinking, clogging, and displacement is to repeat the procedure. Not only does repeating the procedure cause more harm to the patient due to increased risk of procedural complications. It also causes valuable time to be wasted; lengthening the patient’s “Golden Window” and decreasing patient viability.


The TensionSquare effectively eliminates catheter kinking, flex based occlusion, and dislodgement.


By mitigating the factors that directly contribute to patient mortality, the TensionSquare improves the patient’s chances of survivability, eliminates the need for a repeat procedure due to intervention failure, and allows for more effective and less invasive catheter placement at the mid-axillary position.
