Manufacturer Reason
for Recall		 Miscalculation reading. A software error in the firm's EUB-5500/HI VISION diagnostic scanning system causes a miscalculation of the left ICA/CCA ratio when using the Carotid Calculation package for patient scans.
FDA Determined
Cause 2		 Software design
Action A Device Correction Letter was issue by the firm on 02/25/2008. The letter asks the affected customers not to use the value of ICA/CCA on the Measurement Report for diagnosis, but instead to follow the Immediate countermeasure detailed in the 'Note in Use' document which accompanies the Device Correction letter. The customers are asked to follow the Immediate Countermeasure until they receive a Temporary Countermeasure to correct the ICA/CCA ratio calculation. The Temporary Countermeasure will include: 1) a Disk to import a new carotid measure package; 2) an Installation booklet detailing how to import the new carotid measurement package and optional customization tools; and 3) an Operator manual addendum Upon release of the countermeasure, the firm's Applications or Servcie personnel shall perform the corrective action as identified in the Service Pack (A) Installation Instructions. Finally, upon release of the next software revision, service personnel will replace the software at each customer location.
