Handheld Photocosmetic Device
First Claim
1. A handheld photocosmetic device for performing fractional treatment of tissue by a user, comprising a housing, an EMR source disposed in the housing, and an EMR delivery path within the housing and optically coupled to the light source, wherein the EMR delivery path is configured to apply EMR generated by the EMR source to a plurality of discrete locations located within a treatment area of the tissue and wherein a total area of the plurality of discrete locations is less than the treatment area;
- and wherein the device is configured to be self-contained within or about the housing such that substantially the entire device can be handheld by the user during operation.

Abstract
The present invention discloses handheld photocosmetic devices that can be utilized to apply EMR to the skin, e.g., to achieve fractional treatment of the skin. The invention discloses effective fractional photocosmetic devices for use in by a consumer in a non-medical and or non-professional setting. Thus, embodiments of such devices are disclosed herein that have one or more of the following attributes: capable of performing one or more cosmetic and/or dermatological treatments; efficacious for such treatments; durable; relatively inexpensive; relatively simple in design; smaller than existing professional devices (with some embodiments being completely self-contained and hand-held); safe for use by non-professionals; and/or not painful to use (or only mildly painful).

51. A photocosmetic system, comprising
a handheld portion extending from a proximal end to a distal end, an EMR source disposed in the handheld portion, a plurality of EMR-delivery modules, each of the modules being adapted for removable and replaceable coupling to the distal end of the handheld portion for delivery of light from the source to a plurality of distributed discrete skin locations, wherein each of the light-delivery module provides a different pattern of the discrete locations.
-
60. A photocosmetic device, comprising
a housing extending from a proximal end to a distal end, a plurality of light sources disposed in the housing configured to direct light through the distal end of the housing to a plurality of separated discrete skin locations, a motion sensor mounted to the housing to sense a speed of movement of the distal portion to the skin, a controller in communication with the motion sensor and the light sources, the controller controlling the sources based on the speed so as to direct light from the source to a plurality of separated discrete skin locations.

64. A method for performing fractional treatments of tissue using a handheld photocosmetic device, comprising:
-
irradiating in a first treatment a plurality of separated treatment spots within a target area of tissue with EMR, wherein the total area of the plurality of treatment spots is less than the area of the target area;
irradiating in a second treatment a second plurality of separated treatment spots within the target area of tissue with EMR, wherein the total area of the second plurality of treatment spots is less than the area of the target area;
wherein the second irradiating step occurs after the first irradiating step and wherein at least the second irradiating step is performed using a self-contained handheld photocosmetic device.
