Predicate Device Identification 510(k) Number: k081214 Product Name: Styla microlaser / Styla Ortho Manufacturer: Zap Lasers, LLC 510(k) Number: k093852 Product Name: iLase Manufacturer: Biolase Technology, Inc. - 6. Device Description PenLase is a surgical equipment, simple tool, portable, and easy to use. It is a tool that can be used for the treatment of oral soft tissue surgery, plastic surgery. The PenLase utilizes a semiconductor diode which consists of semiconductor "chips" made from Aluminum, Gallium and Arsenide, together commonly referred to as AlGaAs , with invisible infrared radiation as a laser source. The laser power is delivered to the treatment area via a fiber tip. The disposable fiber tips are bendable in a variety of angle for maximum access to all areas of the mouth. PenLase delivers 0.7 Watts and 1.7 Watts with wavelength 810±10 nm of continue laser power without cords, outlets or foot switches, which makes its battery life last longer. . · {2}------------------------------------------------ ge of 5 Project #: M0222011Bd The PenLase charging station recharges up to two PenLase batteries simultaneously, a fully charged battery can last for several patients or procedures.

Non-Clinical Test Conclusion Bench tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards: IEC 60825-1: 2007, Safety of laser products - Part 1: Equipment classification, requirements. IEC 60601-2-22: 1995, Medical Electrical Equipment – Part 2: Particular requirements for the safety of diagnostic and therapeutic laser equipment. IEC 60601-1:1988+A1:1991+A2:1995, Medical Electrical Equipment - Part1: General requirements for safety. IEC 60601-1-2:2007, Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests (Edition 3). ISO 10993-5: 2009, Biological evaluation of medical devices -- Part 5: Tests for In Vitro cytotoxicity. ISO 10993-10: 2002/Amd.1:2006, Biological evaluation of medical devices - Part 10: Tests for irritation and delayed-type hypersensitivity. #### 8. Substantially Equivalent Conclusion The proposed device, Dental Laser Therapy System, is determined to be Substantially Equivalent (SE) to the predicate device, Styla microlaser / Styla Ortho (k081214) and iLase (k093852), in respect of safety and effectiveness. Analysis 1: The output power of proposed device is between that of the two predicates devices, and all of them comply with IEC 60825-1 and IEC 60601-2-22. So the difference will not affect the safety and effectiveness of the proposed device. III-4 {4}------------------------------------------------ Project #: M0222011Bd III-5 Analysis 2: the class of the aiming beam of proposed device is lower than that of the iLase, which means the proposed device has lower hazards. And all of them comply with IEC 60825-1 and IEC 60601-2-22. So the difference will not affect the safety and effectiveness of the proposed device. Analysis 3: the Fiber tip diameter, beam diameter, spot size of proposed device are similar to that of the Styla Microlaser / Styla Ortho and iLase, and all of them comply with IEC 60825-1 and IEC 60601-2-22. So the difference will not affect the safety and effectiveness of the proposed device. Analysis4: the button switch and foot switch are both intended to provide the handpiece on/off capabilities. And all of them comply with IEC 60825-1 and IEC 60601-2-22. So the difference will not affect the safety and effectiveness of the proposed device. Analysis5: the dimension of the three devices does not affect the effectiveness of laser. And all of them comply with IEC 60825-1 and IEC 60601-2-22. So the difference will not affect the safety and effectiveness of the proposed device. {5}------------------------------------------------ Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
