SUPPLEMENTARY INFORMATION: I. Background In the 
                    **Federal Register**
                     of March 15, 1999 (64 FR 12774), FDA published a proposed rule to reclassify 38 preamendments class III devices into class II and to establish special controls for these devices. Interested persons were given until June 14, 1999, to comment on the proposed rule. A trade association requested that FDA reopen the comment period for the following six devices: (1) Vascular graft prosthesis of less than 6 millimeters diameter, (2) pacemaker lead adaptor, (3) annuloplasty ring, (4) cardiopulmonary bypass defoamer, (5) cardiopulmonary bypass arterial line blood filter, and (6) cardiopulmomonary bypass oxygenator. The request noted that FDA had not made the guidance documents that were proposed as special controls for these six devices available for comment through the agency's Good Guidance Practices (GGP's). The request further noted that it was impossible to comment on the proposed reclassification without the guidance documents being available. Therefore, the trade association requested that FDA extend the comment period until at least 90 days after the guidance documents are publicly available for comment. FDA also identified an additional three devices for which the agency had 
                    ( print page 20934)
                    not issued the guidance documents proposed as special controls in accordance with the GGP policy: The indwelling blood carbon dioxide partial pressure (Pco2) analyzer, the indwelling blood hydrogen ion concentration (pH) analyzer, and the indwelling blood oxygen partial pressure (Po2) analyzer. In the near future, FDA intends to announce the availability of two guidance documents for these three devices and will reopen the comment period on the reclassification of those devices at that time. Accordingly, FDA is reopening the comment period for the March 15, 1999, proposed rule to allow additional time for interested persons to comment on the following six devices: Table 1
