Piranha Medical, LLC was created in 2018 to address the more than 40,000 food impaction incidences throughout the US and more globally. The Piranha GI cores and suctions food into a catheter; that allows clearance of the bolus with no pile-up of food, leaves the field for good visualization and helps in avoiding aspiration risks. Piranha now has several innovative catheter solutions in the Gastrointestinal, Pulmonary, and Pancreatic markets.

“The Piranha coring catheter is the only device available that resolves food impactions and maintains a clear field. It is designed to work rapidly and safely, and is Teflon coated to facilitate food suction. The catheter works by coring out the center of a food impaction allowing easy distal passage of food."
