## Abstract

A system and method for treatment of skin including a treatment surface having numerous small energy emitting points for fractional skin treatment as well as negative pressure outlets. During a treatment, negative pressure from the outlets may exert a pulling force on an opposing tissue surface to bring the tissue into contact with the energy points.

## Claims

### Claim 1

A method of treating human tissue, comprising:
applying a treatment surface to said tissue, said surface including a plurality of energy emission points and a plurality of negative pressure outlets;
exerting a pulling force from said negative pressure outlets against a tissue opposing said treatment surface; and
energizing a first group of said plurality of energy emission points before an energizing of a second group of said plurality of energy emission points;
wherein said pulling force from a first of said plurality of outlets pulls a first area of said tissue into contact with a first of said energy emission points, and said pulling force from a second of said plurality of outlets pulls a second area of said tissue into contact with a second of said energy emission points;
wherein the energy emission points have a diameter in the range of 100 microns to 1000 microns, to allow fractional treatment of the tissue and wherein said plurality of energy emission points are interspersed among said plurality of negative pressure outlets and said plurality of energy emission points are arranged in a first array on said surface and said plurality of said outlets are arranged in a second array on said surface, said first array overlapping said second array.

### Claim 2 (depends on 1)

The method as in claim 1, comprising exerting said pulling force from said plurality of outlets, said pulling concurrently with emission of energy from said energy emission points.

### Claim 3 (depends on 1)

The method as in claim 1, comprising capturing in a storage cavity behind said surface, debris released from said tissue by said negative pressure.

### Claim 4 (depends on 1)

The method as in claim 1, comprising varying in a pulse, a level of energy emitted by a first group of said plurality of energy emission points.
