Action

The firm, Radiometer America, sent two Urgent "Medical Device Field Correction" letters issued on February 4, and on February 24th, 2011. The letters described the product, problem and actions to be taken. The customers were instructed to replace the sensor cassette. In order to prevent this situation from occurring, the firm informed the customers in the recall/correction notification that they intend to upgrade all ABL 90 Flex analyzers to a new software version. The new software will perform a check during a normal system FLUSH in order to allow the analyzer to detect the bias and will notify the customer immediately of this condition and will automatically disable the cassette thus preventing further use. The letter goes on to remind the device customers that until such time as the software upgrade is installed, they should make sure to adhere to the procedures stated in the Reference Manual which call for the replacement of the sensor cassette immediately upon receiving message #1310. The letter further instructs the customer to complete and return the attached FAX RETURN FORM via fax to 440-871-0463. The letter also states that the expected release date for the new software should be sometime in the second half of February 2011. If you have any questions regarding this letter, or the upgrade, please contact Technical Support staff at 1-800-736-0600 Opt 4.
