Abstract

Methods and devices including a skin or a lip and more particularly methods and devices that enhances absorption of fluid treatment media into tissue for cosmetic and therapeutic purposes.

First claim

What is claimed is:

1 . A method for treating a targeted tissue of a subject, comprising:
providing an applicator with a distal tip having a perimeter portion surrounding an aspiration portion, a plurality of spherical rolling members carried in one or more arc-shaped receiving channel spaces in the aspiration portion, contacting the targeted tissue with the distal tip, where the perimeter portion seals the distal tip against the targeted tissue; applying negative pressure thereby suctioning targeted tissue against the aspiration portion and moving the distal tip over the targeted tissue while suctioning such that the targeted tissue stretches over the plurality of spherical rolling members, causing the applicator to manipulate the targeted tissue.

2 . The method of claim 1 , wherein the negative pressure draws a fluid from a fluid source through a first port in the aspiration portion to hydrate the targeted tissue.

3 . The method of claim 2 , wherein the fluid is drawn from the fluid source that is at least one of a remote fluid source and a fluid source carried by the applicator.

4 . The method of claim 2 , wherein applying negative pressure comprises and a second port in the aspiration portion communicating with a negative pressure source.

5 . The method of claim 4 , wherein the first port and the second port are disposed on opposing sides of the one or more arc-shaped receiving channel spaces.

6 . The method of claim 1 , wherein the one or more arc-shaped receiving channel spaces extend from 90 to 360 degrees around the aspiration portion.

7 . The method of claim 1 , wherein the distal tip has an abrasive portion and wherein moving the distal tip over the targeted tissue abrades tissue.

8 . A device for treating a targeted tissue of a subject, comprising:
an applicator body; a negative pressure source; a distal tip of the applicator body having a perimeter portion configured for contacting the targeted tissue, wherein the perimeter portion surrounds an aspiration portion; a plurality of spherical rolling members carried in one or more arc-shaped receiving channel spaces in the aspiration portion; wherein contacting and moving the distal tip against the targeted tissue when applying a negative pressure from the negative pressure source causes the targeted tissue to stretch over the plurality of spherical rolling members, wherein the perimeter portion forms a seal against the targeted tissue to cause the negative pressure source to draw fluid from a fluid source into the aspiration portion.

9 . The device of claim 8 , wherein the one or more arc-shaped receiving channel spaces extend from 90 to 360 degrees around the aspiration portion.

10 . The device of claim 8 , wherein the one or more arc-shaped receiving channel spaces have a constant radius.

11 . The device of claim 8 , wherein the one or more arc-shaped receiving channel spaces have a varying radius.

12 . The device of claim 8 , further comprising at least one first port in the aspiration portion communicating with the negative pressure source and a second port in the distal tip in communication with a fluid source.

13 . The device of claim 8 , wherein the one or more arc-shaped receiving channel spaces have a concentric configuration.

14 . The device of claim 8 , wherein each of the one or more arc-shaped receiving channel spaces carry at least three spherical rolling members.

15 . The device of claim 8 , wherein a distal-facing surface of the aspiration portion is concave.

16 . The device of claim 8 , wherein a surface area of the plurality of spherical rolling members comprises at least 25% of a total surface area of a distal-facing surface of the distal tip.

17 . The device of claim 8 , further comprising a recessed groove on at least one side of the one or more arc-shaped receiving channel spaces.

18 . The device of claim 8 , wherein at least one edge of the one or more arc-shaped receiving channel spaces is configured to abrade or remove tissue.

19 . The device of claim 8 , wherein the plurality of spherical rolling members have a diameter ranging from 1 mm to 5 mm.
