Valleylab Ligasure Features The LigaSure™ vessel sealing system gives you something no other electrosurgical tool can - permanent vessel occlusion. The LigaSure™ system's revolutionary technology replaces almost all other hemostatic tools because it doesn't just ligate vessels, it actually fuses vessel walls to create a permanent seal. Provides a combination of pressure and energy to create vessel fusion Permanently fuses vessels up to and including 7 mm in diameter and tissue bundles without dissection or isolation Average seal cycle is 2 to 4 seconds Seals withstand 3 times normal systolic blood pressure Feedback-controlled response system automatically discontinues energy delivery when the seal cycle is complete, eliminating the guesswork Valleylab Ligasure Specifications Dimensions Height: 38.6 cm (15.2 in) Width: 40.6 cm (16.0 in) Depth: 12.7 cm (5.0 in) not including feet Weight: 5.9 Kg (13 lbs) typical General Output configuration: Isolated output Cooling: Natural convection Display: Two (2) digital seven-segment displays: 1.9 cm (0.75 in.) each Mounting: A Valleylab cart (UC8009) or a stable flat surface Operating Parameters Ambient temperature range: 10° to 40° C (50° to 104° F) Relative humidity: 15% to 90%, noncondensing Atmospheric pressure: 700 to 1060 millibars Warm-up time: If transported or stored at temperatures outside the operating temperature range, allow one hour for the generator to reach room temperature before using Audio Volume The stated audio level is for the activation tone and alarm tone at a distance of one meter.
