An elongate electrode is configured to flex and generate plasma to incise tissue. An electrical energy source operatively coupled to the electrode is configured to provide electrical energy to the electrode to generate the plasma. A tensioning element is operatively coupled to the elongate electrode. The tensioning element can be configured to provide tension to the elongate electrode to allow the elongate electrode to flex in response to the elongate electrode engaging the tissue and generating the plasma. The tensioning element operatively coupled to the flexible elongate electrode may allow for the use of a small diameter electrode, such as a 5 μm to 20 μm diameter electrode, which can allow narrow incisions to be formed with decreased tissue damage. In some embodiments, the tensioning of the electrode allows the electrode to more accurately incise tissue by decreasing variations in the position of the electrode along the incision path.

Plasma gas is ejected from inner gas ejection ports that are formed in a downstream side housing, and nitrogen gas is supplied as protective gas to a protective gas source between a housing and a cover section. Nitrogen gas is sucked in accompanying exhaust from inner gas ejection ports of plasma gas, and is ejected from the outer gas ejection ports. In this case, since a layer of nitrogen gas is formed in the periphery of plasma gas, it is possible to make it difficult to bring the plasma gas into contact with air, and it is possible to make it difficult to react a reactive species such as a radical in the plasma gas, oxygen in the air, and the like.

The plasma is formed between electrodes to be energized from an electric power source, containing a partially ionized mass having a luminescence region including neutral atoms (NA), primary electrons (PE), secondary electrons (SE), and ions.

The method comprises the interspersed steps of: accelerating the primary electrons (PE) toward one of said electrodes (10) polarized by a short, positive, high voltage pulse, impacting primary electrons (PE) against said electrode (10) and ejecting secondary electrons (SE) from it; subsequently, accelerating the secondary electrons (SE) toward the luminescence region by polarization of said electrode (10) by a negative voltage with a lower voltage pulse colliding the secondary electrons with neutral atoms (NA) and producing positive ions (PI) and derived electrons (DE); the negative pulse must have a period of time sufficient to accelerate the positive ions (PI) of the luminescent region towards the electrodes 10, striking the surface of said electrodes; repeating the previous steps in order to obtain a steady state plasma with a desired degree of ionization. The control of the intensity and the period of the positive and negative pulses allow the control of the degree of ionization and the volume of the luminescent region of the plasma.
