Monopolar Lesion Comparison Images
Nimbus monopolar technique created a robust 10.91mm diameter lesion.
The standard 18g cannula monopolar technique produces a 5.29mm diameter lesion.
Nimbus monopolar technique created a robust 10.75mm diameter lesion.
The cooled RF monopolar technique produces a similar 10.75mm diameter lesion.
Nimbus monopolar technique created a robust 10.91mm diameter lesion.
The 18g protruding electrode monopolar technique produces a 5.11mm diameter lesion.
Bipolar Lesion Comparison Images
Nimbus bipolar technique created a robust 32.12mm diameter lesion.
The 18g protruding electrode bipolar technique revealed an 8.65mm gap, resulting in an incomplete lesion when used under the same conditions.
Laboratory Testing Conditions
The tissue in this test was warmed to 37 degree celsius to simulate body temperature in a water bath. The tissue used in these images was chicken breasts.
For the monopolar testing the radiofrequency generator was set to 80 degrees celsius for 80 seconds with a 30 second ramp for both the Nimbus and the standard 18g cannula.
For the bipolar testing the radiofrequency generator was set to 85°C for 150 seconds for 150 seconds with a 30 second ramp for both the Nimbus and the standard 18g cannula.
