Recall Insight
This recall's affected scope, documented in the Recall Profile below, stays within a single-region or limited-distribution footprint. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
Within the same product category the archive holds 6 closely related recalls, 6 from FDA Devices - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Product description
The Medtronic StrataMR adjustable valves and shunts are designed to provide continuous cerebrospinal fluid (CSF) flow from the ventricles of the brain into the right atrium of the heart or the peritoneal cavity. The design enables the physician to non-invasive adjust valve pressure/performance level pre- and post-implantation by using magnetic adjustment tools without the need for radiographic confirmation. After surgical implantation, the Medtronic Neurosurgery StrataMR valves provide a non-invasive method to address changing patient needs in the management of hydrocephalus. The valve design enables the physician to adjust the valve pressure/performance level using the Medtronic StrataMR Adjustment Tools. The StrataMR valves are intended to maintain performance level setting under magnetic resonance imaging (MRI) exposure when scanned in accordance with the MRI conditions in the labeling. The StrataMR valves, small and regular, provide the full range of performance levels: 0.5, 1.0, 1.5, 2.0, and 2.5. The currently set performance level is discernible through use of the Indicator Tool or by x-ray (for corresponding settings, refer to figure 6). The dome is designed to allow needle puncture via a 25-gauge or smaller noncoring needle. The StrataMR valve can be flushed in either the distal or proximal direction by percutaneous finger pressure. Occluders are located proximally and distally to the central reservoir on the StrataMR valve regular and only distally on the small model to facilitate selective flushing.
Reason for recall
Incorrect valve rotor orientation due to misalignment and/or off-center positioning of the StrataMR Locator Tool: When the StrataMR valve is set in the incorrect orientation, higher valve opening pressures result leading to a corresponding underdrainage in CSF fluid performance. This condition may result in the following adverse health consequences: ventriculomegaly, headaches, nausea, vomiting and lethargy. If left untreated, underdrainage has the potential to lead to coma and death.
