Publication number: 20140121631Abstract: A method for providing localized heating of the dermal layers of skin of a patient, using energy in the form of a group of pulses having defined parameters in a controlled manner. This method preferably uses an optical delivery system to deliver pulsed energy to a specific spot of skin so that targeted layers of the affected skin are heated to a desired temperature range. The temperature range is optimally selected to maximize treatment efficacy while minimizing pain to the patient. Example applications include reducing wrinkles, acne, hair, scar tissue, warts, and promoting wound healing. In this method, the temperature of the selected locus rises quickly to the desired temperature range, then is maintained within a controlled range with a relatively flat temperature profile. The method maintains the temperature by controlling one or more of a pulse energy intensity, pulse width, and pulse frequency or time delay between pulses.Type: ApplicationFiled: October 29, 2013Publication date: May 1, 2014Inventors: David M.

Patent number: 8623040Abstract: In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.Type: GrantFiled: July 1, 2009Date of Patent: January 7, 2014Assignee: Alcon Research, Ltd.Inventors: Alexander N.
