Abstract

Claims (31)

1 . A skin treatment system comprising:

a main body portion, the main body portion comprising a receiving area configured to receive a treatment material container, the main body portion comprising a longitudinal axis;

a waste container configured to be removably secured to the main body portion;

a rechargeable battery;

a base for receiving the main body portion;

a tip configured to be removably secured to the main body portion, the tip comprising a peripheral lip and at least one waste port;

a pump;

at least one fluid delivery conduit placing an interior of a treatment material container secured to the receiving area in fluid communication with the tip; and

at least one waste conduit placing the at least one waste port of the tip in fluid communication with the pump, wherein activation of the pump creates a vacuum along the at least one waste conduit and the at least one waste port;

wherein the pump is configured to transfer waste materials from the tip to the waste container via the at least one waste conduit;

wherein the pump is configured to contact waste materials being transferred to the waste container; and

wherein the rechargeable battery is configured to be recharged when the main body portion is positioned within the base and the base is operatively coupled to an electric energy source.

2 . The system of claim 1 , wherein the pump comprises a liquid pump.

3 . The system of claim 1 , wherein the pump does not comprise an air pump.

4 . The system of claim 1 , wherein the pump comprises a metering or dosing pump.

5 . The system of claim 1 , wherein the pump comprises a diaphragm pump.

6 . The system of claim 1 , wherein the pump comprises one of the following pump types: a peristaltic pump, a piezoelectric pump, a gear pump, a piston pump, a syringe and another type of micro pump.

7 . The system of claim 1 , wherein the system comprises a handpiece or handheld device configured for personal use by a subject undergoing a skin treatment procedure.

8 . The system of claim 1 , further comprising at least one controller for regulating at least one operational aspect of the pump.

9 . The system of claim 8 , wherein the at least one operational aspect of the pump comprises a flowrate and/or pressure of liquid passing through the pump.

10 . The system of claim 1 , wherein the tip comprises a rollerball, the rollerball positioned within an interior area defined by the peripheral lip and being configured to contact skin when the system is in use.

11 . The system of claim 10 , wherein the rollerball extends distally past the peripheral lip of the tip.

12 . The system of claim 1 , wherein the tip comprises at least one interior baffle to reduce a likelihood of short-circuiting fluid flow to the at least one waste port, wherein the at least one interior baffle is positioned within an area defined by the peripheral lip.

13 . The system of claim 1 , wherein the tip is configured to abrade skin tissue as the system is moved relative to skin tissue of a subject.

14 . The system of claim 13 , wherein the peripheral lip is configured to at least partially abrade skin tissue as the system is moved relative to skin tissue of a subject.

15 . The system of claim 1 , wherein the pump is configured to create suction along the tip when the longitudinal axis of the main body portion is maintained at an angle between 0 and 110 degrees relative to vertical.

16 . The system of claim 1 , further comprising at least one illumination source configured to provide light to the waste container.

17 . The system of claim 16 , wherein the at least one illumination source comprises at least one light emitting diode (LED).

18 . The system of claim 1 , wherein a suction created at the tip by the pump is 0 to 5 pounds per square inch (psi).

19 . The system of claim 1 , wherein a maximum suction created at the tip by the pump is 5 pounds per square inch (psi).

20 . The system of claim 1 , wherein the receiving area is configured to receive a disposable pod.
