Abstract: A machine for reprocessing catheters of the type having a double lumen, one of which leads to a balloon. A used catheter is sealed within a cassette which in turn is connected by multiple ports to a cleaning side of the machine. Cleaning solution is flushed through the inside and outside of the catheter. The balloon integrity is tested by adding step wise volume additions and monitoring the pressure. The data generated is compared to a standard curve for new catheters. The cleaned, sterile catheter is then rinsed to remove all traces of sterilant. Sterile saline is alternatively flushed through the cassette and catheter. The balloon is again tested for leaks. No portion of the rinse side of the machine requires sterilizing except for the disposable tubing set and saline source. The rinsed, clean and sterile catheter is removed from the cassette for reuse.
