Reason for Recall
Incorrect Software Validation- The ARC treatment plans containing a Dose Dynamic MLC for IMRT delivery that will not be recognized properly by the system. Under these circumstances, an arc plan can be administered to a patient whereby the gantry will not rotate, resulting in delivery to a single location rather than through the gantry arc.
Firm Action
An Urgent Medical Device Correction letter was distributed October 2, 2007, to all direct consignees, informing them that the ARC treatment plans containing a Dose Dynamic MLC for IMRT delivery will not be recognized properly by the System. The firm provided corrective instructions and informed consignees that a product modification will be developed to resolve the issue. A Varian Service Representative will be scheduling a visit to upgrade the application.
