{0}------------------------------------------------ JUN 25 1998 K981126 #### 510(k) SUMMARY ### Ceralas G Frequecy Doubled Nd:YAG Laser Systems (including the Ceralas G3 Laser and Accessories) ## Submitter's Name, Address, Telephone Number, Contact Person and Date Prepared Submitted by Regulatory Counsel for: CeramOptec, Inc. 515 Shaker Road East Longmeadow, Massachusetts 01028 413-525-0600 Phone: Facsimile: 413-525-0611 Carol Morello, V.M.D. Contact Person: Date Prepared: March 26, 1998 #### Name of Device and Name/Address of Sponsor Ceralas G Frequency Doubled Nd: YAG Laser System and Accessories("Ceralas G3") CeramOptec, Inc. 515 Shaker Road East Longmeadow, Massachusetts 01028 #### Common or Usual Name Frequency Doubled Nd: YAG Laser #### Classification Name Laser surgical instrument for use in general and plastic surgery and in dermatology. #### Predicate Devices CeramOptec's Ceralas G Frequency Doubled Nd:YAG Laser System and Accessories (K954834, K923953, K943445, and K951775), the Iris Medical DioLite 532 (K964074), and the Continuum Biomedical CB Diode/532 Laser (K954905). {1}------------------------------------------------ #### Intended Use The Ceralas G Frequency Doubled Nd:YAG Laser System, the Ceralas G3 laser and accessories, is intended as a surgical instrument for use in the photocoagulation of vascular and pigmented skin lesions. ### Technological Characteristics and Substantial Equivalence The Ceralas G3 is a complete, self-contained, compact surgical laser system that utilizes a diode pumped neodymium-doped yttrium aluminum garnet (Nd:YAG) laser whose output is frequency doubled to produce radiation in the green visible spectrum at 532 nm. Frequency doubling is achieved by the use of an intercavity Potassium Titanyl Phosphate ("KTP") crystal. KTP is a crystalline material that has nonlinear optical properties which allows the input of light of one color and output of a different light color. Specifically, it allows infrared light in and emits green light. The laser employs a modular design which includes: 1) laser crystal; 2) cooling module; 3) built in power meter with automatic calibration; 4) continuous or pulsed operating modes; and 5) front controls with a display panel. The laser system delivers up to 3 Watts of optical power. The exposure mode for the laser is selectable from 0.10 Watts to 3 Watts at 532 nm. The Ceralas G3 is identical to the Ceralas G Frequency Doubled Nd: YAG Laser Systems that has already received clearance from FDA (K954834). The Ceralas G has already been cleared for the intended use as a surgical instrument for photocoagulation and is indicated for use in ocular tissue. This submission adds an additional indication for the Ceralas G as a surgical instrument for photocoagulation of vasculare and pigmented skin lesions. The delivery systems for the Ceralas G Frequency Doubled Nd: Y AG Laser Systems consist of an optical fiber in a coaxially mounted protective sheath which is fitted with an SMA connector at the proximal end. The fiber is a bare, polished quartz fiber provided in a 200 micron to 1400 micron diameter range. The delivery systems are hand-held, designed to fit the Ceralas G3, and deliver the laser energy via the SMA connector which couples it to the laser. The Ceralas the delivery systems are supplied sterile. These systems are identical to those MegaBeam Fiber Optic Delivery Systems, which range in fiber sizes of 200 to 1200 micron diameters, and have already been cleared by the FDA. CeramOptec, the manufacturer of the MegaBeam Fiber Optic Delivery Systems, has previously obtained clearance for the use of these delivery systems as accessories to laser systems for any indication for which compatible Nd:YAG, 1.44 YAG, Ho:YAG, KTP, Argon and Diode laser systems are cleared (K923953, K943445, and K951775). This submission includes additional fiber sizes up to a 1400 micron diameter. The Ceralas G3 has the same intended use, similar principles of operation and similar technological characteristics as previously cleared predicate laser systems. The {2}------------------------------------------------ Ceralas G3 and its predicate devices, the CeramOptec Ceralas G Frequency Doubled Nd: YAG Laser Systems (K954834), the Iris Medical Diolite 532 (K964074), and the Continuum Biomedical, Inc. CB Diode/532 Laser System (K954905), have the identical intended use. The Ceralas G3, like its predicate device, is a solid state laser that emits a beam in the near-infrared region of the electromagnetic spectrum. Furthermore, the Ceralas G3, the Iris Medical Diolite 532 (K964074), and the Continuum Biomedical, Inc. CB Diode/532 (K954905), all employ diode pumped frequency doubled neodymium doped yttrium aluminum garnet laser crystals to generate the treatment beam. The wavelength of all of these lasers is 532nm. Each of the lasers offers continuous and pulsed exposure modes. Thus, the laser tissue interaction and the surgical performance of the Ceralas G3, the Iris Medical Diolite 532, and the Continuum Biomedical, Inc. CB Diode/532, would be expected to be the same. The Ceralas G3 and all of the predicate devices (K964074, K954905, and K954834) exhibit comparable power outputs of 0.1 to 3 Watts and all are air cooled. All of these devices utilize essentially the same types of fiber optic delivery accessories to transmit the laser energy to the target tissue. The Ceralas G3 delivery systems and the predicate device delivery systems likewise operate in the contact and non-contact modes. The Ceralas G3 fiber delivery systems are available with fiber core diameters of 200 to 1400 microns similar to the Diolite 532 predicate device delivery systems (K964074). Any differences between the Ceralas G3 and the predicate devices, such as the systems' dimensions and weight, do not raise new questions of safety and effectiveness. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
