Abstract

Claims (24)

1 . A method of treating a skin tissue of a patient, the method comprising:

positioning a distal end of a handpiece for skin treatment on a skin surface of a subject, the handpiece comprising a tip and at least one abrasive member at or near the distal end of the tip, wherein the handpiece is configured to receive a container at a handpiece proximal end, the container comprising a rollerball, the rollerball in fluid communication with a first fluid within the container, wherein the rollerball is configured to contact skin tissue when the handpiece is in use;

creating a suction force along the tip, wherein a suction source is in fluid communication with the tip by at least one suction passageway, and wherein, when the at least one suction passageway is coupled to the suction source and the suction source is activated, the suction force is created along the distal end of the tip; and

advancing the handpiece along the skin tissue of the patient;

wherein advancing the handpiece along the skin tissue of the patient draws the first fluid from an inner chamber of the container to the skin tissue; and

wherein advancing the handpiece along the skin tissue of the patient abrades the skin tissue with the at least one abrasive member.

2 . The method of claim 1 , wherein creating the suction source forms a partial seal between the skin tissue and the tip.

3 . The method of claim 1 , wherein the at least one abrasive member is selected from the group consisting of: a spiral member, a post, an abrasive surface, and an abrasive pad.

4 . The method of claim 1 , wherein the at least one abrasive member is located on, near, or along the tip, the at least one abrasive member configured to selectively exfoliate the skin tissue during use.

5 . The method of claim 1 , wherein the tip further comprises a peripheral lip, wherein the at least one abrasive member and the peripheral lip are configured to contact the skin surface during use.

6 . The method of claim 1 , further comprising applying a second fluid to the skin surface, wherein the handpiece further comprises a dissolving material in fluid communication with the first fluid, wherein the dissolving material is configured to dissolve in the first fluid, wherein the second fluid comprises the dissolving material, and wherein the second fluid is created as the first fluid is drawn from the container through the dissolving material.

7 . A method of treating a skin tissue of a patient, the method comprising:

positioning a distal end of a handpiece for skin treatment on a skin surface of a subject, the handpiece comprising a tip and at least one abrasive member at or near the distal end of the tip, the at least one abrasive member configured to at least partially abrade skin tissue when the handpiece is moved relative to skin tissue during a skin treatment procedure, wherein the handpiece is configured to receive a container at a handpiece proximal end, the container comprising a rollerball, the rollerball in fluid communication with a first fluid and a second fluid, wherein the rollerball is configured to contact skin tissue when the handpiece is in use;

creating a suction force along the tip, wherein a suction source is in fluid communication with the tip by at least one suction passageway, and wherein, when the at least one suction passageway is coupled to the suction source and the suction source is activated, the suction force is created along the distal end of the tip; and

advancing the handpiece along the skin tissue of the patient,

wherein advancing the handpiece along the skin tissue of the patient draws at least one fluid from the container to the skin tissue; and

wherein advancing the handpiece along the skin tissue abrades the skin tissue of the patient.

8 . The method of claim 7 , wherein the at least one abrasive member is selected from the group consisting of: a spiral member, a post, an abrasive surface, and an abrasive pad.

9 . The method of claim 7 , wherein the first fluid is a first treatment material and the second fluid is a second treatment material, wherein the first treatment material and the second treatment material are different.

10 . The method of claim 9 , further comprising selecting which treatment fluid is drawn from the container.

11 . The method of claim 7 , wherein two treatment fluids are applied to the skin surface.

12 . The method of claim 11 , further comprising applying a third fluid to the skin surface.

13 . The method of claim 12 , wherein the third fluid is drawn from the container, the third fluid separated from the first fluid and the second fluid by chambers in the container.

14 . The method of claim 12 , wherein the handpiece further comprises a dissolving material in fluid communication with the first fluid, wherein the dissolving material is configured to dissolve in the first fluid, wherein the third fluid comprises the dissolving material, and wherein the third fluid is created as the first fluid is drawn from the container through the dissolving material.
