A cryosurgery machine used in hospitals across all 50 states can build up enough internal pressure to rupture the probe a doctor is holding inside a patient, and the trigger is something as ordinary as a firm tug on a hose.
Erbe USA is correcting 11,226 ERBECRYO 2 cryosurgical units after determining that a strong pull on the high-pressure transfer hose can create what the company calls a pneumatic short circuit between the gas inlet and the connector. Carbon dioxide leaks into the return path, pressure climbs beyond design limits, and the attached cryoprobe can rupture.
