On November 24, 2004, ThermoGenesis Corp. (the "Company") provided update on a press release on its Thrombin Processing Device ("TPD") and DAC System for the semi-automated separation of whole blood. The FDA determined that the TPD is not substantially equivalent to devices marketed in interstate commerce prior to May 28, 1976 or to any device which has been reclassified into Class I or Class II and therefore, the TPD has been classified by statute into Class III (Pre-Market Approval ("PMA")). The FDA has reviewed the DAC System 510(k) submission for the semi-automated separation of whole blood and freezing of blood components and requires additional information to complete its determination of substantial equivalency to devices marketed in interstate commerce. ThermoGenesis has recently provided additional information for the FDA's review. Additional information can be found on the press release attached as Exhibit 99.
