Abstract
A medical device for providing nonthermal plasma treatment to a patient by generating sufficient nonthermal plasma in the presence of the flow of an oxygen-free gas mixture that can quickly and safely treat infection or promote wound healing in the desired region wherein the device is flexible and easy to maneuver in difficult to access regions such as the nose, paranasal sinuses, throat, esophagus, and ears of a patient and wherein the device comprises an integrated vacuum/suction to capture reactive species that are generated by plasma to prevent the patient from inhaling harmful byproducts.
Claims14
A cold plasma device comprising:
- a probe, said probe comprising a conductor wire extending from a proximal end to a distal end and having a tip at said distal end;
- wherein the conductor wire comprises an insulating material along a length of the probe from the proximal end to the distal end with a portion of noninsulated material at each end of the conductor wire and wherein the tip comprises a conductive gallium alloy, said gallium alloy having a melting point of about 40° C.;
- a first passage having a first opening adjacent to the tip and a second passage having a second opening adjacent to the tip, said first passage being a gas delivery line and said second passage being a suction line, said first passage and said second passage disposed on opposing sides of the probe with the probe positioned centrally and in line between the first passage and the second passage;
- wherein the first opening and the second opening each are dimensioned to be noncircular, having a first dimension along a width and a second dimension along a length;
- and
- a power source generating 10,000-45,000 V at a pulse of 0.1 μs to 1 s in duration applied at 100 Hz to 10,000 Hz.
