Intended Use

The METRx™ Microscope is indicated for visualization of the surgical field in any area of the body cut open during a surgical procedure. When used in the cervial, thoracic, or lumbar spine either from an anterior or posterior direction, for example, the METRx Microscope and accessories are intended to aid the surgeon’s visualization of the surgical area and allow him/her to perform any type of surgical spinal procedure such as herniated disc repair, visualization of the circumferential decompression of the nerve roots, aiding in the search and removal of nucleus material, spinal fusion, or insertion of spinal implants. Other examples of generic surgical use of the METRx Microscope would be for use in the knee, ankle, shoulder, hand, wrist, and temporomandibular joint (TMJ).

Device Story

METRx System is a surgical microscope designed for visualization of surgical fields. Device provides optical magnification to assist surgeons during open procedures, including spinal surgeries (e.g., herniated disc repair, decompression, fusion) and joint surgeries (e.g., knee, ankle, shoulder, TMJ). Operated by surgeons in clinical/OR settings. Device aids in identifying anatomical structures and surgical targets, facilitating precise instrument manipulation and tissue removal. Benefits include enhanced visualization of surgical sites, potentially improving procedural accuracy and outcomes.

Technological Characteristics

Surgical microscope system. Optical visualization device. No software, electronic processing, or energy-based sensing described.

Indications for Use

Indicated for visualization of surgical fields during open surgical procedures, including spinal (cervical, thoracic, lumbar) and joint (knee, ankle, shoulder, hand, wrist, TMJ) surgeries. Intended for use by surgeons to aid visualization during procedures such as herniated disc repair, nerve root decompression, nucleus removal, spinal fusion, and implant insertion.

Regulatory Classification

Identification

Dear Dr. Treharne:

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 requirement, 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.
