Abstract
A plasma coating device for treating a wound comprises a plasma chamber having: one or more electrodes, a gas supply inlet, a plasma outlet exposed to ambient pressure, and an ignition system operatively connected to the electrodes for providing a non-thermal equilibrium plasma within the plasma chamber. An aerosol delivery system is operable to introduce a bioresorbable material as an aerosol into the plasma, to produce a coating on the wound surface.
Claims14
A method for treating a patient, the method comprising:
- generating a non-thermal equilibrium plasma at a frequency between 100 kHz and 500 kHz via an electrode housed in a plasma chamber with a wall opposite an outlet exposed to ambient pressure, wherein the electrode extends through a first lumen parallel to a second lumen, wherein the wall defines an opening of the first lumen adjacent to an opening of the second lumen;
- introducing an aerosol comprising a bioresorbable material through the opening of the second lumen into the plasma chamber and the non-thermal equilibrium plasma through the distal opening of the second lumen;
- and
- contacting tissue of the patient with reactive species emanating from the plasma and with the aerosol downstream of the outlet to form a coating on the tissue, wherein the coating is bioresorbable.

A method for treating a patient, the method comprising:
- generating a non-thermal equilibrium plasma at a frequency between 100 kHz and 500 kHz via an electrode housed in a plasma chamber with a wall opposite an outlet exposed to ambient pressure, the wall defining a first opening containing a distal tip of the electrode and a second opening adjacent to the first opening, wherein the electrode extends through a first lumen parallel to a second lumen, the first lumen terminating at the first opening and the second lumen terminating at the second opening;
- introducing an aerosol comprising a bioresorbable material through the second opening into the plasma chamber and the non-thermal equilibrium plasma, such that the bioresorbable material contacts the non-thermal plasma within the plasma chamber and exits the plasma chamber with the non-thermal equilibrium plasma;
- and
- forming a coating comprising the bioresorbable material on tissue of the patient by directly contacting the tissue with the plasma and the aerosol downstream of the plasma chamber, wherein the tissue is part of a wound, wherein the coating is bioresorbable, and wherein the bioresorbable material in the coating is biologically-active.
