About Us

Inventors and visionaries, the scientists behind the innovation at CLR (“Clear”) Medical are inspired to act by the possibilities of a better tomorrow. For more than a decade, the team has brought evidence-based solutions to market to elevate the practice of medicine in meaningful ways.

Motivated by a call from the U.S. Department of Defense for a solution to the vexing problem of retained blood in the pleural space after chest trauma (retained hemothorax), the team has brought forth its latest contribution to medicine – the CLR Irrigator.

Designed in close collaboration with trauma surgeons, the CLR Irrigator facilitates the proven practice of thoracic irrigation through indwelling thoracic catheters. Thoracic irrigation with CLR is simple, safe, and seamless, giving patients the best possible outcomes while reducing both the financial burden and extended length of stay resulting from retained hemothorax. With benefits like these, it’s no surprise that CLR-facilitated thoracic irrigation is becoming part of standard hemothorax care at hospitals across the United States.
