The A.T.S. 1500 Automatic Tourniquet System is a dual-port, dual-cuff system with microprocessor controls and dedicated ports for supplying and measuring pressure independently. The Zimmer ATS 1500 temporally occludes blood flow in a patient's extremities during surgical procedures, hence can be useful in producing a bloodless operating field in surgical procedures. Single and Dual Port Options: All cuff styles are available in both single and dual port configurations, allowing for use with any Zimmer A.T.S. tourniquet system. Single port cuffs for use with the A.T.S. 750 and A.T.S. 1200 Tourniquet Systems. Dual port cuffs for use with A.T.S. 1500 and ATS 2000 Tourniquet Systems.
