Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is announcing the availability of the draft guidance for industry and FDA staff entitled “Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters.” The draft guidance was developed as the special controls to support the reclassification of PTCA catheters, other than cutting/scoring PTCA catheters, from class III (premarket approval) into class II (special controls). This draft guidance describes a means by which PTCA catheters, other than cutting/scoring PTCA catheters, may comply with the requirement of special controls for class II devices. Elsewhere in this issue of the Federal Register, FDA is issuing for public comment the recommendation of the Circulatory System Devices Panel (the Panel) to reclassify PTCA catheters, other than cutting/scoring PTCA catheters, from class III to class II. This draft guidance is not final nor is it in effect at this time.
Although you can comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the agency considers your comment on this draft guidance before it begins work on the final version of the guidance, submit written or electronic comments on the draft guidance by August 28, 2008.
Submit written requests for single copies of the draft guidance document entitled “Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters” to the Division of Small Manufacturers, International, and Consumer Assistance (HFZ-220), Center for Devices and Radiological Health, Food and Drug Administration, 1350 Piccard Dr., Rockville, MD 20850. Send one self-addressed adhesive label to assist that office in processing your request, or fax your request to 240-276-3151. See the SUPPLEMENTARY INFORMATION section for information on electronic access to the guidance.
Submit written comments concerning this draft guidance to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.

The draft guidance document was developed as a special control guidance to support the reclassification of PTCA catheters, other than cutting/scoring PTCA catheters, into class II (special controls). The device is intended for balloon dilatation of a hemodynamically significant coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion; treatment of acute myocardial infarction, treatment of in-stent restenosis, and/or post-deployment stent expansion.
On September 21, 2000, FDA filed a petition submitted under section 513(f)(3) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360c(f)(3)) from Cook Group Inc. (COOK) requesting reclassification of PTCA catheters from class III into class II. (This reclassification petition did not include cutting or scoring PTCA catheters.) In accordance with section 513(f)(1) of the act, the PTCA catheter was automatically classified into class III because the PTCA catheter was not within a type of device which was introduced or delivered for introduction into interstate commerce for commercial distribution before May 28, 1976, and had not been found substantially equivalent to a device placed in commercial distribution after May 28, 1976, which was subsequently reclassified into class II or class I.
At a public meeting on December 4, 2000, the Panel recommended (seven to one) that PTCA catheters, other than cutting/scoring PTCA catheters, be reclassified from class III to class II, when indicated for balloon dilatation of a hemodynamically significant coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial Start Printed Page 31128perfusion; or for treatment of acute myocardial infarction. The Panel believed that class II with special controls, such as this draft guidance document, would reasonably ensure the safety and effectiveness of the device.
The Panel recommended that PTCA catheters for the treatment of in-stent restenosis and/or post-deployment stent expansion not be included because of a lack of sufficient information about this use. Since the Panel meeting, however, additional data regarding this use have become available and have been reviewed by the agency. Following the public meeting, FDA reviewed adverse event reports submitted to FDA's Manufacturer and User Facility Device Experience Database (MAUDE). The agency believes that the types of risks associated with the use of PTCA catheters for the treatment of in-stent restenosis and/or post-deployment stent expansion are similar enough to the risks associated with treatment of de novo lesions, such that the special controls discussed at the Panel meeting, with the addition of recommendations for specific nonclinical performance testing and the recommendation that in-stent restenosis patients be included in the clinical evaluation, when necessary, are adequate to control the risks to health for these devices.
II. Significance of Guidance
This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the agency's current thinking on this topic. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute and regulations.
