  • Reason
    The purpose of this letter is to advise you that medtronic is updating the instructions for use (“ifu”) for the neuray® and merocel® neurosurgical patties. the updated instructions for use provided include precautions that will help reduce the potential for clinical consequences when neurosurgical patties, which are designed to be x-ray detectable or radiopaque to assist with post-procedural removal in the event of a missing device, are not visible during x-ray imaging. therefore, medtronic is including the following precautions: • “count all devices before and after the procedure prior to surgical closure. in the event a device cannot be located; an x-ray can be used to locate the devices. only the radiopaque markers are visible on imaging. the size and position of the radiopaque markers may impact their visibility." • "it is recommended that at least three views, using the optimal parameters for the imaging (x-ray) equipment, at a variety of angles (e.G., 45 degrees, 22.5 degrees, and 0 degree angles) for anterior and posterior, or the appropriate plane, be taken and examined for a missing device. if there are concerns regarding visualization, consult with your local imaging expert to establish the optimal radiographic parameters (e.G., kvp, mas) for visualization with the imaging equipment.” • “avoid cutting the patties because fragments without x-ray detectable material may enter the surgical site. fragments left in the surgical site may result in an unintended adverse reaction.” • “the locator string will not be visible by x-ray as it is not radiopaque. avoid using the locator strings to remove the patties from the surgical site to prevent detachment.” .
