Methods and systems for trans-tissue substance delivery using plasmaporation
Exemplary systems and methods associated with trans-tissue substance delivery using non-thermal plasma to porate skin or tissues using contoured dielectrics/electrodes and grounding techniques. In some embodiments, a substance delivery system may be incorporated into the plasma generating device for automatically controlled skin treatments. In other embodiments, a skin treatment patch may include the electrode and the treatment substance.
1. An apparatus for providing a substance associated with a skin treatment, comprising:
a treatment patch applied to skin associated with the skin treatment, wherein the treatment patch comprises:
a substrate that flexibly conforms to a shape of the skin; and
a substance reservoir for holding a treatment substance associated with the skin treatment; and
a plasma generating device for generating a plasma;
a power supply for powering the plasma generating device; and
first circuitry for providing one or more electrical pulses to the plasma generating device;
wherein the plasma generating device and the treatment patch are configured to apply the plasma and the treatment substance to the skin during the skin treatment.
2. The apparatus of claim 1 , wherein the treatment substance is applied to the skin through a hole in a high voltage electrode for creating the plasma above the skin.
3. The apparatus of claim 1 , wherein the treatment substance is applied to the skin through a hole in a dielectric barrier for preventing a high voltage electrode of the plasma generating device from contacting the skin.
4. The apparatus of claim 1 , wherein the treatment patch further comprises microneedles.
5. The apparatus of claim 1 , wherein the treatment patch further comprises a high voltage electrode for creating the plasma above the skin.
6. The apparatus of claim 1 , wherein the treatment patch further comprises at least one spacer for providing a gap between a dielectric barrier for preventing a high voltage electrode of the plasma generating device from contacting the skin and the skin surface.
7. The apparatus of claim 1 , wherein the treatment patch further comprises a dielectric barrier for preventing a high voltage electrode of the plasma generating device from contacting the skin.
8. The apparatus of claim 7 , wherein the dielectric barrier is configured to expose the treatment substance to the skin when the dielectric barrier is removed from the treatment patch.
9. The apparatus of claim 1 , wherein the treatment patch further comprises a high voltage electrode for creating the plasma above the skin, a dielectric barrier for preventing the high voltage electrode of the plasma generating device from contacting the skin, and at least one spacer for providing a gap between the dielectric barrier and the skin surface, and wherein the treatment patch is configured such that removing at least one of the dielectric barrier and the at least one spacer from the treatment patch exposes the treatment substance to the skin.
10. The apparatus of claim 1 , wherein the substance reservoir is between the substrate and a dielectric barrier for preventing a high voltage electrode of the plasma generating device from contacting the skin.
11. The apparatus of claim 1 , wherein the treatment patch comprises at least one connection to an electrical circuit.
12. The apparatus of claim 11 , wherein the electrical circuit comprises a grounding path.
13. The apparatus of claim 1 , wherein the substance reservoir provides the treatment substance to the skin during the skin treatment.
14. The apparatus of claim 1 , wherein the plasma generating device comprises a non-thermal DBD plasma generator.
15. The apparatus of claim 1 , wherein the plasma generating device and the treatment patch are configured to apply the plasma to the skin before the treatment substance during the skin treatment.
16. An apparatus for providing a skin treatment, comprising:
a plasma generating device for generating a plasma;
a power supply for powering the plasma generating device; and
a treatment patch applied to skin associated with the skin treatment, wherein the treatment patch comprises a substrate that flexibly conforms to a shape of the skin, and wherein the treatment patch provides a treatment substance to the skin during the skin treatment;
wherein the plasma generating device and the treatment patch are configured to apply the plasma and the treatment substance to the skin during the skin treatment.
17. The apparatus of claim 15 , wherein the treatment patch comprises a connection to a grounding circuit.
18. The apparatus of claim 15 , wherein the plasma generating device comprises a non-thermal DBD plasma generator.
