Lamp for use in a tissue treatment device
First Claim
Patent Images
1. A source of electromagnetic radiation for use in a device for treating tissue, comprising:
- a halogen lamp including an envelope, an electrical connector, and a filament;
a reflective covering disposed about said envelope, said covering being substantially opaque and configured to provide at least one opening through which electromagnetic radiation produced by the lamp and reflected by the covering can pass for application to the tissue to be treated.

Abstract
Electromagnetic radiation (EMR) sources for efficiently transmitting EMR, such as light and near infrared radiation, to tissue to be treated using various cosmetic, dermatological and medical procedures is described. In one aspect, an EMR source includes a coating that has the properties of absorbing relatively little EMR and exhibiting relatively high levels of scattering of EMR. In another aspect, an EMR source is used in a dermatological treatment device that heats tissue at depth. In another aspect, an EMR source is used in a light source assembly that can be incorporated into treatment devices.

21. A light source assembly for use in a device for treating tissue, comprising:
-
a lamp having an envelope disposed about a filament;
a reflective covering disposed about said lamp, said covering configured to form at least one opening through which electromagnetic radiation that is produced by the lamp and reflected from the covering can pass; and
a first window configured to irradiate tissue with electromagnetic radiation from the at least one opening during operation of the light source assembly. - View Dependent Claims (22)
