Abstract

One aspect of the present disclosure relates to a treatment probe comprising an elongated body member and a needle portion. The elongated body member can have a proximal end portion and a distal end portion. The needle portion can be connected to the distal end portion. The needle portion can include at least one electrode and at least one fluid port. The at least one electrode and the at least one fluid port can be configured to deliver electrical energy and a tumescent fluid, respectively, so that superficial tissue planes overlying a target nerve are protected from inadvertent heat damage as a result of application of electrical energy to a target nerve.

Claims

1. A treatment probe comprising:

an elongated body member having a proximal end portion and a distal end portion; and

a needle portion connected to said distal end portion, said needle portion including at least one electrode and at least one fluid port, said at least one electrode and said at least one fluid port being configured to deliver electrical energy and a tumescent fluid, respectively, so that the electrical energy is delivered to the target nerve, but not to superficial tissue planes overlying the target nerve, and the superficial tissue planes overlying a target nerve are protected from inadvertent heat damage as a result of application of electrical energy to a target nerve, said at least one electrode being disposed on an outer surface of said needle portion and located opposite said at least one fluid port;

wherein said needle portion includes an elongated shaft having a closed, sharpened distal end;

wherein said at least one fluid port is configured to deliver a tumescent fluid flow away from the target nerve;

wherein electrical energy delivered by said at least one electrode is directed away from the flow of tumescent fluid through said at least one fluid port;

wherein said needle portion further includes at least one sensing electrode that is axially spaced apart from said at least one electrode.

2. The treatment probe of claim 1, wherein said at least one electrode and said at least one fluid port are radially offset from one another.

3. The treatment probe of claim 1, wherein said at least one electrode and said at least one fluid port are radially aligned with one another.

4. The treatment probe of claim 1, wherein said at least one electrode and said at least one fluid port are axially offset from one another.

5. The treatment probe of claim 1, wherein said body member includes a power button disposed thereon.

6. The treatment probe of claim 1, wherein the tumescent fluid is stored within said body member.

7. The treatment probe of claim 1, wherein said shaft of said needle portion further comprises:

an inner circumferential surface; and

an outer circumferential surface;

wherein said at least one fluid port extends between said inner and outer circumferential surfaces to form an opening in fluid communication with a channel that extends through said needle portion.

8. The treatment probe of claim 1, further comprising a power source that is housed within said elongated body member so that said treatment probe is free from connection with an external power source.

9. The treatment probe of claim 1, wherein the at least one sensing electrode that is disposed on an outer surface of said needle portion and opposite of said at least one fluid port.

10. The treatment probe of claim 1, further comprising a fluid aspiration and delivery mechanism in fluid communication with a channel of said needle portion.

11. A treatment probe comprising:

an elongated body member having a proximal end portion and a distal end portion; and

a needle portion connected to said distal end portion, said needle portion including at least one electrode and at least one fluid port, said at least one electrode and said at least one fluid port being configured to deliver electrical energy and a tumescent fluid, respectively, so that the electrical energy is delivered to the target nerve, but not to superficial tissue planes overlying the target nerve, and the superficial tissue planes overlying a target nerve are protected from inadvertent heat damage as a result of application of electrical energy to a target nerve, said at least one electrode being disposed on an outer surface of said needle portion and located opposite said at least one fluid port; and

a power source that is housed within said elongated body member so that said treatment probe is free from connection with an external power source;

wherein said needle portion includes an elongated shaft having a closed, sharpened distal end;

wherein said at least one fluid port is configured to deliver a tumescent fluid flow away from the target nerve;

wherein electrical energy delivered by said at least one electrode is directed away from the flow of tumescent fluid through said at least one fluid port.

12. A treatment probe comprising:

an elongated body member having a proximal end portion and a distal end portion; and

a needle portion connected to said distal end portion, said needle portion including at least one electrode and at least one fluid port, said at least one electrode and said at least one fluid port being configured to deliver electrical energy and a tumescent fluid, respectively, so that the electrical energy is delivered to the target nerve, but not to superficial tissue planes overlying the target nerve, and the superficial tissue planes overlying a target nerve are protected from inadvertent heat damage as a result of application of electrical energy to a target nerve, said at least one electrode being disposed on an outer surface of said needle portion and located opposite said at least one fluid port;

wherein said needle portion includes an elongated shaft having a closed, sharpened distal end;

wherein said at least one fluid port is configured to deliver a tumescent fluid flow away from the target nerve;

wherein electrical energy delivered by said at least one electrode is directed away from the flow of tumescent fluid through said at least one fluid port;

wherein the tumescent fluid is stored within said body member.
