The PK Technology platform allows surgeons to perform a variety of procedures with a broad range of devices that cut, coagulate and seal to minimize blood loss and shorten procedure times. PK Technology provides unique, pulsed, low-voltage RF energy to resect rapidly at low temperatures virtually eliminating tissue charring. It combines the safety of saline with “seal-as-you-cut” tissue resection and vaporization for treatment of BPH with no risk of hyponatremia. Patients benefit from shorter than average catheterization times and can be treated on an outpatient basis. The PK working elements provide compatibility with Gyrus ACMI resectoscopes.
