Devices and systems for treating the skin using vacuum
An instrument and technique for the removal of epidermal layers in a controlled manner utilizing a hand-held instrument with a working end that (i) a vacuum aspiration system, (ii) a source for delivery of a sterile fluids or pharmacological agents to the skin; and (iii) a skin interface surface in the working end that has specially shape structure for abrading surface layers of the patient's epidermis as the working end is moved over the patient's skin while at the same time causing rapid penetration of the fluids into the skin for therapeutic purposes. Movement of the working end across the skin causes abrasion of the surface layers in a path over the patient's skin.
1. A handheld device for treating a skin surface, comprising:
a body comprising a housing;
a working end portion positioned along a first end of the body, the working end portion comprising a distal end configured to contact a skin surface, wherein the working end portion comprises a perimeter along the distal end configured to contact the skin surface, a skin interface positioned along the interior of the perimeter, wherein the skin interface is configured to contact the skin surface during use;
a first aperture arrangement comprising at least one first port located along or near the working end portion, the at least one first port being in fluid communication with a vacuum source via at least one waste passageway extending through the housing; and
a second aperture arrangement comprising at least one second port located along or near the working end portion, the at least one second port being in fluid communication with a hydration treatment media source;
wherein the vacuum source is configured to create a vacuum within the at least one waste passageway and the working end portion, and wherein the vacuum source is configured to simultaneously deliver a treatment media from the hydration treatment media source to the working end portion and remove spent treatment media away from the working end portion via the at least one waste passageway;
wherein, when the vacuum source is activated and the working end portion of the device is positioned along a skin surface, hydration treatment media is delivered to the skin surface through the at least one passageway and the at least one second port due to the vacuum generated along the working end portion by the vacuum source, and spent treatment media is, at least partially, simultaneously aspirated away from the working end portion through the at least one first port by the same suction force generated by the vacuum source.
2. The device of claim 1 , wherein the at least one passageway extends at least partially through an interior of the housing.
3. The device of claim 1 , further comprising a filter located between the working end portion and the vacuum source.
4. The device of claim 1 , wherein the working end portion is removably positioned along a distal end of the housing.
5. The device of claim 1 , wherein the working end portion comprises plastic.
6. The device of claim 1 , wherein the working end portion is at least partially transparent.
7. The device of claim 1 , wherein, when in use, the vacuum source draws skin through an aperture defined by the perimeter of the working end portion to facilitate contact between the working end portion and the skin surface.
8. The device of claim 1 , wherein the at least one passageway comprises a conduit that extends proximally from the housing of the device to the vacuum source.
9. The device of claim 1 , further comprising a vacuum source.
10. The device of claim 1 , wherein the at least one second port is in fluid communication with the hydration treatment media source via a treatment media passageway.
11. The device of claim 1 , wherein the hydration treatment media source is separate from to the handheld device.
12. The device of claim 1 , wherein the hydration treatment media source comprises a reservoir.
13. A system for treating a skin surface, comprising:
a hydration treatment media source;
a handheld device comprising:
a body comprising a housing;
a working end portion positioned along a first end of the body, the working end portion comprising a distal end configured to contact the skin surface, wherein the working end portion comprises a perimeter along the distal end configured to contact the skin surface, a skin interface positioned along the interior of the perimeter, wherein the skin interface is configured to contact the skin surface during use;
a first aperture arrangement comprising at least one first port located along or near the working end portion; and
a second aperture arrangement comprising at least one second port located along or near the working end portion, the at least one second port being in fluid communication with the treatment media source; and
a single vacuum source in fluid communication with the at least one first port via at least one passageway;
wherein, when the single vacuum source is activated and the working end portion of the device is positioned along a skin surface, a hydration treatment media is delivered to the skin surface through the at least one passageway and the at least one second port, and spent treatment media is simultaneously, at least partially, aspirated away from the working end portion through the at least one first port.
14. The system of claim 13 , wherein, when in use, the vacuum source draws skin through an aperture defined by the perimeter of the working end portion to facilitate contact between the working end portion and the skin surface.
15. The system of claim 13 , wherein the at least one second port is in fluid communication with the hydration treatment media source via a treatment media passageway.
16. The system of claim 13 , wherein the hydration treatment media source is separate from to the handheld device.
17. The system of claim 13 , wherein the hydration treatment media source comprises a reservoir, and wherein the reservoir is separate from to the handheld device and is in fluid communication with the handheld device using at least one treatment media conduit.
18. The system of claim 13 , wherein the hydration treatment media comprises at least one of the following: water, saline, a chemical agent and an acid.
19. The device of claim 13 , wherein a reservoir is housed in the handheld device.
20. The device of claim 1 , wherein a reservoir containing the hydration treatment media source is housed in the housing of the body.
21. The device of claim 1 , wherein the skin interface comprises ridge and valley elements.
22. The device of claim 1 , wherein the skin interface comprises an irregular or ridged surface structure.
23. The device of claim 1 , wherein the working end portion comprises a medical grade plastic.
24. The device of claim 1 , wherein the working end portion is transparent.
25. The device of claim 13 , wherein the skin interface comprises ridge and valley elements.
26. The device of claim 13 , wherein the skin interface comprises an irregular or ridged surface structure.
27. The device of claim 13 , wherein the working end portion comprises a medical grade plastic.
28. The device of claim 13 , wherein the working end portion is transparent.
