20120232539 | Radiation-Based Dermatological Devices and Methods - A self-contained, hand-held device for providing a dermatological treatment includes a device body configured to be handheld by a user; a radiation source supported in the device body, the radiation source including a beam source configured to generate an energy beam; an application end configured to be manually moved across the surface of the skin during a treatment session; electronics configured to pulse the radiation source during the treatment session such that the beam source emits pulsed energy beams to the skin; and a displacement control system including a displacement sensor configured to determine a displacement of the device relative to the skin, and electronics configured to control at least one operational parameter of the device based on the determined displacement of the device relative to the skin. | 09-13-2012 |
20120283710 | Devices and Methods for Radiation-Based Dermatological Treatments - A hand-held device for providing laser-based dermatological treatments includes a laser beam source supported in a device body, an automated scanning system, and control electronics. The automated scanning system is configured to receive an input beam generated by the laser beam source and scan the input beam to provide a series of output beams for delivery to the skin via an application end of the device to form a pattern of treatment spots on the skin. The application end is configured for movement across the skin during a treatment session. The control electronics control the laser beam source and/or the automated scanning system to deliver the scanned output beams to the skin at a radiation intensity sufficient to provide an effective dermatological treatment, and wherein the scanned output beams delivered from the application end of the device meet the Class 1M or better eye safety classification per the IEC 60825-1. | 11-08-2012 |
20120283712 | Devices and Methods for Radiation-Based Dermatological Treatments - A hand-held device for providing a dermatological treatment by scanning a laser beam to form a pattern of treatment spots on the skin includes a laser source that generates an input beam, an automated scanning system, and a treatment spot control system. The automated scanning system includes a rotating multi-sector scanning element configured to repeatedly scan the input beam, each scan providing an array of output beams corresponding to the multiple sectors of the scanning element and forming a scanned row of treatment spots on the skin. The scanning element is configured such that each sector provides a constant-angular-direction output beam as that sector rotates through the input beam. The treatment spots of each scanned row are spaced apart from each other by areas of non-irradiated skin. The treatment spot control system provides a distance between adjacent rows of treatment spots in a direction of manual movement of the device. | 11-08-2012 |
