Devices, systems and methods for subdermal coagulation

A surgical method comprising:

• creating an entry incision through a patient's skin;
• aspirating fat from a subcutaneous tissue plane beneath the patients skin via the entry incision, the subcutaneous tissue plane including individual bands of a fibroseptal network;
• applying helium-based plasma in the subcutaneous tissue plane, the helium-based plasma coagulates the individual bands and reduce laxity in the patient's skin, the helium-based plasma finds untreated bands of the individual bands that represents the path of least resistance for flow of RF energy in a plasma beam, the path of least resistance being a band having lower impedance relative to an adjacent band;
• and
• drawing the helium-based plasma through the subcutaneous tissue plane such that the path of least resistance constantly changes, in response to increasing tissue impedance of the treated individual bands, and the helium-based plasma alternates to at least one other band of the individual bands to effect 360 degree tissue treatment,
• wherein a current used to generate the helium-based plasma is selected such that, as impedance of the treated individual bands increases, the helium-based plasma alternates to an untreated individual band to limit heating of the treated bands.
