Abstract
Medical devices for generating an aerosol and plasma, e.g., for therapeutic treatment are described. The medical device may include a nebulizer, the nebulizer including an outer compartment, an inner compartment, and a needle radially inward of the inner and outer compartments. The medical device may include at least one electrode and a chamber, wherein a distal-facing surface of the chamber defines at least one plasma outlet and a nozzle in communication with the nebulizer, an end of the electrode being proximate the plasma outlet.
Claims30
A medical device comprising:
- a housing that includes a nebulizer, the nebulizer comprising:
- an outer compartment in communication with a gas inlet,
- an inner compartment in communication with a fluid channel and a fluid inlet, and
- a needle;
- wherein the needle is radially inward of the inner compartment, the inner compartment is radially inward of the outer compartment, and a distal end of the outer compartment is in communication with a distal end of the inner compartment;
- at least one electrode;
- and
- a chamber defined by a distal end portion of the housing;
- wherein a distal-facing surface of the chamber defines at least one plasma outlet and a nozzle in communication with the nebulizer;
- and
- wherein an end of the electrode is proximate the plasma outlet.
A medical device comprising:
- a housing that includes a nebulizer, the nebulizer comprising:
- an outer compartment,
- an inner compartment, and
- a needle;
- wherein the needle is radially inward of the inner compartment, the inner compartment is radially inward of the outer compartment, and a distal end of the outer compartment is in communication with a distal end of the inner compartment;
- a fluid reservoir coupled to a fluid inlet, the fluid reservoir containing a liquid that comprises at least one therapeutic agent;
- at least one electrode;
- and
- a chamber defined by a distal end portion of the housing;
- wherein a distal-facing surface of the chamber defines at least one plasma outlet and a nozzle in communication with the nebulizer;
- and
- wherein an end of the electrode is proximate the plasma outlet.
A medical device comprising:
- a housing that includes a nebulizer, the nebulizer comprising:
- an outer compartment in communication with a gas inlet,
- an inner compartment in communication with a fluid inlet, and
- a needle;
- wherein the needle is radially inward of each of the inner compartment and the outer compartment, and a distal end of the outer compartment is in communication with a distal end of the inner compartment;
- at least one electrode;
- a fluid reservoir coupled to the fluid inlet;
- and
- a chamber defined by a distal end portion of the housing;
- wherein a distal-facing surface of the chamber defines at least one plasma outlet and a nozzle in communication with the nebulizer;
- and
- wherein an end of the electrode is proximate the plasma outlet.
A method of treating tissue of a subject, the method comprising exposing the tissue to plasma and/or an aerosol comprising at least one therapeutic agent using the medical device of any of the previous claims.
