Electrosurgical units that uses helium plasma and radiofrequency energy as well as standard monopolar and bipolar energy to heat tissue. The device uses a pressurized helium tank to drive radiofrequency energy into a hollow cannula. The radiofrequency waveform converts the helium gas into a cold plasma. These units are used to cut, coagulate, and ablate soft tissue during open and laparoscopic surgical procedures and can be used for subdermal coagulation.
