The Laserscope Microbeam IV Micromanipulator is intended to be used in conjunction with a microscope for all cleared Laserscope indications for the KTP/532 and KTP/YAG Surgical Laser Systems. ## Device Story The Laserscope Microbeam IV is a micromanipulator accessory for surgical laser systems. It receives laser energy via fiber optic cable and delivers it to a localized surgical site. The device features an optical assembly that focuses the beam in line with the microscope's viewing path. Surgeons operate the device using two manual adjustments: a fine focus knob for precise tissue targeting and a rapid defocus knob to adjust the laser spot size (250-400 microns). It is compatible with most surgical microscopes and objective lenses. By enabling precise, microscope-guided laser delivery, the device assists surgeons in performing procedures cleared for KTP/532 and KTP/YAG laser systems, facilitating accurate tissue treatment. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Optical assembly for laser delivery; manual fine focus and rapid defocus adjustments; spot size range 250-400 microns; compatible with standard surgical microscopes and objective lenses; conforms to 21 CFR 1040.10 and 1040.11 laser performance standards. ## Regulatory Identification (1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon. ## Predicate Devices - Laserscope Microbeam Micromanipulators ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The Microbeam IV is used in conjunction with a microscope that allows the surgeon to accurately position the laser; the Microbeam IV can produce a spot size from 250 microns to 400 microns. The Microbeam IV system consists of an optical assembly which focuses the laser light from the fiber optic cable to the surgical site. The Microbeam IV delivers the laser energy in line with the viewing path. There are two focusing adjustments on the Microbeam IV; the fine focus and the rapid defocus. The fine focus adjustment is used to focus the laser beam at the tissue. The rapid defocus knob quickly increases the laser spot size at the tissue. The Microbeam IV is compatible with most microscopes and can be used with most objective lenses. Laserscope Premarket Notification for Microbeam IV Micromanipulator 000010 {1} Laserscope Premarket Notification for Microbeam IV Micromanipulator 000011 # SUMMARY OF SAFETY AND EFFECTIVENESS, PAGE 2 ## DEVICE CLASSIFICATION: To the best of our knowledge, Microbeam IV Micromanipulators have not been specifically classified; however, the surgical lasers for which they are intended have been classified as Class II medical devices by the OB/GYN, General Plastic Surgery, and ENT Device Advisory Panels. ## PERFORMANCE STANDARDS: The Laserscope KTP/532 and KTP/YAG Surgical Laser Systems conform with federal regulations and the performance standards 21 CFR 1040.10 and 1040.11 for medical laser systems. Laserscope is unaware of any specific standards for micromanipulators. ## INDICATION FOR USE STATEMENT: The Laserscope Microbeam IV Micromanipulator is intended to be used in conjunction with a microscope for all cleared Laserscope indications for the KTP/532 and KTP/YAG Surgical Laser Systems. ## COMPARISON WITH PREDICATE DEVICE: In the opinion of Laserscope, the Laserscope Microbeam IV is substantially equivalent to the existing family of Laserscope Microbeam Micromanipulators. The risks and benefits for the Laserscope Microbeam IV Micromanipulator are comparable to the predicate device when used for similar clinical applications. Since the Laserscope Microbeam IV Micromanipulator is substantially equivalent with respect to indications for use, materials, method of operation and physical construction to the predicate device, we believe it clearly meets the requirements for substantial equivalence according to Section 510(k) guidelines. Safety and effectiveness are reasonably assured, therefore justifying 510(k) clearance for commercial sale. {2} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 JUN 30 1997 Ms. Lisa McGrath Sr. Regulatory Affairs Specialist Laserscope 3052 Orchard Drive San Jose, California 95134-2011 Re: K971250 Trade Name: Laserscope Microbeam IV Micromanipulator Regulatory Class: II Product Code: GEX Dated: March 31, 1997 Received: April 1, 1997 Dear Ms. McGrath: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. {3} Page 2 - Ms. Lisa McGrath This letter will allow you to begin marketing your device as described in your 510(k) premarket notification.
