Product Description

Synergy XVI XVI can incorrectly calculate the target position of the treatment table, because of an error that does not occur very frequently. This is the sequence of events when this error occurs - (1) You do an online VolumeView acquisition and registration. (2) You accept the registration and the Table Move Assistant dialog box appears. (3) The Relative Actual column of the Table Move Assistant dialog box incorrectly appears blank. (4) When this occurs, XVI does not read the Absolute Actual position of the treatment table. This causes XVI to calculate the treatment table moves from the zero position of the treatment table (+0.0, + 0.0, + 0.0). (5) In XVI R5.0, if the Relative Set values are less than or equal to + or -2.5cm (for earlier releases of XVI, the value is + or -2cm), you can do remote automatic table movement (RATM) from the function keypad (FKP). (6) When you press the Table ASU (automatic setup) buttons, the treatment table moves to a position that was incorrectly calculated from XVI.

Reason for Recall

XVI can incorrectly calculate the target position of the treatment table.

Frequently Asked Questions

Contact your healthcare provider and the device manufacturer immediately. Check whether your specific model number and lot number are included in the recall scope. For external devices, stop using the affected product and arrange a replacement. For implanted devices, do not panic — removal is typically not required unless the risk assessment clearly indicates it. Your physician will guide you based on your individual clinical situation and the FDA's recommended actions. Report any adverse effects you may have experienced to FDA MedWatch at 1-800-FDA-1088.

Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency — Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.

Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.

What Should You Do?
