Patent number: 7749260Abstract: Devices and methods for the treatment of skin conditions and lesions are disclosed herein. One aspect of the invention is a compact hand held device that can be safely used by those suffering from skin conditions, such as acne, warts, cold blisters, blemished skin, or fine wrinkles. The devices described herein employ the application of heat for the treatment of skin conditions and lesions. Typically, the peak temperatures employed are about 70° C. to about 400° C. by the devices, are achieved in less than about 1 second, and maintained for less than about 1 second. In some embodiments, the skin surface is heated with heat pulses. Thermal conduction transfers heat from the device to the skin and causes a biological response that accelerates acne clearing, treats blemished skin, itching, or fine wrinkles. The total heat transferred is low enough to prevent burns.Type: GrantFiled: December 9, 2005Date of Patent: July 6, 2010Inventors: Luiz B. Da Silva, George Choi, Joseph Neev

Patent number: 7494492Abstract: A compact hand held device is provided that can be safely used by those suffering from acne, blemished skin or fine wrinkles. The hand held device includes an on/off switch and a button that pulses the device when it is placed on the target site. A battery within the device powers a circuit board and drives a short pulse of current through a heating element, which heats up to approximately 300° C. in less than 0.1 sec. Thermal conduction transfers the heat to the skin and causes a biological response that accelerates acne clearing, treats blemished skin or fine wrinkles. The total heat transferred is low enough to prevent burns.Type: GrantFiled: August 30, 2005Date of Patent: February 24, 2009Assignee: Therative, Inc.Inventors: Luiz B. Da Silva, George Choi

Publication number: 20080047566Abstract: An airway implant device for maintaining and/or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The airway implant device comprises a deformable element to control the opening of an air passageway. Preferably the deformable element is an electroactive polymer element. Energizing of the electroactive polymer element provides support for the walls of an air passageway, when the walls collapse, and thus, completely or partially opens the air passageway. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.Type: ApplicationFiled: September 21, 2007Publication date: February 28, 2008Applicant: Pavad MedicalInventors: Anant Hegde, George Choi, Wally Buch, Kasey Li

Publication number: 20080027520Abstract: Laser treatment of tissue, particularly the tissues in or around the nasal and oral cavities, are described herein. One method for reducing the size of the tissue being treated is to apply laser energy to the underlying tissue. One instrument may be used to deliver laser energy and to optionally provide an infusion or injection of a fluid directly into the tissue as well as optionally provide for ultrasound energy application as well. One or more optical fibers which may extend through needles inserted into the tissue may be utilized to deliver the laser energy.Type: ApplicationFiled: May 18, 2007Publication date: January 31, 2008Applicant: Zoom Therapeutics, Inc.Inventors: George Choi, Kasey Li

Publication number: 20070244529Abstract: Apparatus and methods for the treatment of nasal tissue, particularly the nasal turbinates, are described herein. One method for reducing the size of the inferior nasal turbinate is to apply ultrasound energy to the tissue regions beneath the surface of the turbinate tissue. One instrument may be used to deliver ultrasound energy and to provide an infusion or injection of a fluid directly into the turbinate being treated. The injected fluid can be used to bulk up the size of the turbinate to ensure that the ultrasound energy is properly delivered directly into the intended turbinate tissue. Accordingly, fluids containing anesthetics, fluids infused with analgesics, etc. may be used for pain management while other medications, such as non-steroidal drugs, steroidal drugs, anti-inflammatory drugs, anti-histamines, anti-bacterial drugs, etc., can also be used.Type: ApplicationFiled: April 5, 2007Publication date: October 18, 2007Applicant: Zoom Therapeutics, Inc.Inventors: George Choi, Kasey Li
