Patent number: 6692517Abstract: A method for the reduction in healing time for a wound on the skin of a mammalian patient. The method comprises the steps of providing an optical radiation apparatus with a handpiece communicating therewith, energyzing the optical radiation apparatus to provide a beam of light, and directing the light beam onto a wound or surgical site of a patient. The beam has a wavelength range of about 530 nm to 1000 nm and the beam has a fluence range of from 2 J/cm2 to 5 J/cm2. The beam is preferrably generated by a pulse dye laser apparatus.Type: GrantFiled: April 9, 2001Date of Patent: February 17, 2004Assignee: Cynosure, Inc.Inventors: George Cho, Horace Furumoto, Rafael A Sierra

Publication number: 20020087207Abstract: The present invention includes a method for the prevention of a scar on the skin of a patient after the beginning healing of a wound or surgical site on that patient. The method comprises the steps of providing an optical radiation apparatus with a handpiece communicating therewith, energyzing the optical radiation apparatus to provide a beam of light, directing the light beam onto a wound or surgical site of a patient after 2 days and before 2 months from the date of injury or surgical procedure to the patient. The beam has a wavelength range of about 530 nm to 1000 nm and the beam has a fluence range of from 2J/cm2 to 12J/cm2. The beam is preferrably generated by a pulsed dye laser apparatus.Type: ApplicationFiled: March 12, 2001Publication date: July 4, 2002Inventors: George Cho, Horace Furumoto, Rafael A. Sierra

Patent number: 5312395Abstract: A cutaneous pigmented lesion is treated by irradiation with laser light of between 345 and 600 nm and preferably about 500 nm wavelength. The fluence is between 1 and 10 J/Cm.sup.2 and preferably between 2 and 4 J/cm.sup.2 . The pulse duration is less than 1 .mu.sec and preferably less than 500 nsec. A 3 mm diameter spot is illuminated.Type: GrantFiled: August 21, 1992Date of Patent: May 17, 1994Assignees: Boston University, Candela Laser Corp.Inventors: Oon T. Tan, James C. Hsia, Horace Furumoto

Patent number: 5083549Abstract: A fiber optic endoscope has a shaft with a varying outer diameter. The distal end of the shaft is sufficiently small in outside diameter for maneuvering it through various body canals, and is useful in dilating body orifices to allow more proximal, longer-diameter portions of the shaft to penetrate. The endoscope shaft changes in thickness and is preferably in stages of different constant outside diameter. A flexible tip portion at the distal end of the shaft which is controllable from the endoscope handle may be included. Transitions between adjacent stages are smooth to provide a gradual transition between stages. The endoscope outer shaft is preferably made from a one-piece structure, portions of which are reduced in outside diamter to provide the different stages of the endoscope shaft.Type: GrantFiled: July 25, 1990Date of Patent: January 28, 1992Assignee: Candela Laser CorporationInventors: George E. Cho, Horace Furumoto

Patent number: 5071422Abstract: Calculi, stones, calcified tissue and other material are broken down for removal from within a body using laser pulses that are delivered via an optical fiber and have a wavelength, intensity, energy per pulse and pulse duration selected to break down the object into smaller particles without delivering energy sufficient to cause damage to other tissue.Type: GrantFiled: December 18, 1989Date of Patent: December 10, 1991Assignee: Candela Laser CorporationInventors: Graham Watson, Horace Furumoto

Patent number: 5066293Abstract: A tunable dye laser has been found particularly suited to selective photothermolysis. A longer pulse duration which makes the system suitable for a wider range of applications is obtained by modifying the laser to generate a spatially noncoherent beam. The optical system at each end of the laser cell, which may include a lens or spherical mirror, refocuses the aperture of the dye cell near to itself so that substantially all light emanating from the dye cell is returned to the dye cell until the light passes through one of the optic systems as a noncoherent laser beam. A tunable intracavity element tunes the laser across the gain curve of the dye solution. The pulse duration of the laser beam can be selected from a range of durations up to about one millisecond.Type: GrantFiled: March 10, 1989Date of Patent: November 19, 1991Assignee: Candela Laser CorporationInventor: Horace Furumoto

Patent number: 5029791Abstract: An optics X-Y positioner has an optics support positioned within a housing having sides and front and rear walls. The optics support has a groove on one face which rides in an X direction along a ridge in a sliding guide plate. The guide plate slides within a flat groove in the Y direction in the rear wall of the housing. X and Y direction adjustment screws extend through sides of the frame and abut the optics support. A spring in tension is wrapped about the optics support in a circumferential groove to force the optics support against the adjustment screws.Type: GrantFiled: March 8, 1990Date of Patent: July 9, 1991Assignee: Candela Laser CorporationInventors: Harry L. Ceccon, Horace Furumoto

Patent number: 4961414Abstract: A fiber optic endoscope has a shaft with a varying outer diameter. The distal end of the shaft is sufficiently small in outer diameter for maneuvering it through various body canals, while the overall length of the shaft is rigid enough to allow axial and rotational translation of the shaft when controlled manually from a handle at the proximal end. The endoscope shaft may be n stages of different outer diameter or it may be uniformly tapered along its entire length. Either a step-tapered or a uniformly tapered version may include a flexible tip portion at the distal end of the shaft which is controllable from the endoscope handle.Type: GrantFiled: February 6, 1989Date of Patent: October 9, 1990Assignee: Candela Laser CorporationInventors: George E. Cho, Horace Furumoto
