Eye-safe photocosmetic device
First Claim
1. A method for treating a tissue of a subject with radiation in an eye-safe manner, comprising:
- irradiating said tissue with an eye-safe radiation having a wavelength and intensity chosen to cause an aversive response by said subject when said eye-safe radiation irradiates said subject'"'"'s eye;
waiting a predetermined period of time; and
irradiating said tissue with a treatment radiation when said aversive response does not occur within said period of time;
wherein said tissue is not irradiated with said treatment radiation when said aversive response does occur within said period of time.

Abstract
Devices and methods for treating tissue with radiation, including light and other optical radiation, in a manner that is eye-safe are described. In one embodiment, a photocosmetic treatment device has a cavity into which tissue to be treated is drawn. The device determines whether the tissue is safe to treat and whether the tissue may be tissue associated with the eyes, such as an eyelid. In another embodiment, an eye-safe pulse of radiation is provided at a time interval prior to treatment of the tissue. The pulse is at a wavelength of radiation that the human eye perceives as particularly intense and uncomfortable, even though the pulse is not dangerous or destructive. If the device is oriented to treat eye tissue, directly or through the eyelid, the pulse will cause an aversive reaction in the subject being treated that inhibits the treatment.

15. An apparatus for treating tissue with radiation in an eye-safe manner, comprising:
-
a controller for controlling the production of radiation and configured to provide first and second control signals;
a first radiation source configured to produce in response to said first control signal an eye-safe radiation at an intensity that irritates a subject'"'"'s eye;
a second radiation source configured to produce in response to said second control signal a treatment radiation;
a radiation transmission path configured to transmit radiation from said first radiation source to said tissue through a radiation transmission surface;
a sensor in electrical communication with said controller and configured to provide a sensor signal when said radiation transmission surface is in proximity to said tissue;
wherein said controller is configured to provide said second control signal after a predetermined time interval following said first control signal and when said sensor signal indicates that said radiation transmission surface remains in proximity to said tissue. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. An apparatus for treating tissue with radiation in an eye-safe manner, comprising:
-
a radiation source assembly in electrical communication with a controller;
a waveguide configured to transmit radiation from said radiation source assembly to said tissue;
a sensor in electrical communication with said controller and configured to provide a sensor signal when said radiation transmission surface is in proximity to said tissue;
wherein said radiation source assembly is configured to provide in response to signals from said controller a first radiation that is eye-safe and of an intensity capable of causing an aversive reaction from a subject when irradiating the subject'"'"'s eye, a second radiation that is capable of treating said tissue, said second radiation being provided a predetermined time after said first radiation when said sensor indicates that said waveguide remains in proximity of said tissue. - View Dependent Claims (41, 42, 43, 44)

45. An apparatus for photocosmetic treatment of a subject'"'"'s tissue comprising:
-
a pressure source;
a cavity having an open end, said cavity in fluid communication with said pressure source, and said open end configured to receive said tissue when said pressure source applies pressure;
at least one radiation source configured to transmit radiation into said cavity; and
a sensor configured to issue a sensor signal;
wherein said sensor signal prevents the transmission of radiation from said radiation transmission source when said sensor detects tissue that is not suitable for treatment. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)

62. A method for photocosmetic treatment of a subject'"'"'s tissue comprising:
-
drawing a volume of said tissue into a cavity;
determining whether said volume of tissue is safe to treat using radiation; and
treating said volume of tissue with radiation based on said determination;
wherein said volume of tissue is not treated if it is determined that said tissue is unsafe to treat, and wherein said volume of tissue is treated if it is determined that said tissue is safe to treat. - View Dependent Claims (63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78)
