The Food and Drug Administration (FDA) is announcing that it has issued an order in the form of a letter to Ethicon, Inc., reclassifying the absorbable polydioxanone surgical (PDS) suture intended for use in soft tissue approximation, including use in pediatric cardiovascular tissue where growth is expected to occur and ophthalmic surgery, from class III (premarket approval) to class II (special controls). Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document entitled "Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA," which is immediately in effect as the special control for the PDS suture, but remains subject to public comment and possible future revision under the agency's good guidance practices. The agency is reclassifying this device into class II because new information supplied by the petitioner indicates that special controls, in addition to general controls, will provide reasonable assurance of the safety and effectiveness of the device, and there is sufficient information to establish special controls. Accordingly, the order is being codified in the Code of Federal Regulations. Any firm submitting a premarket notification (510(k)) for a new PDS suture will need to address the issues covered in the special control guidance. However, the firm need only show that its device meets the recommendations of the guidance or in some other way provides equivalent assurances of safety and effectiveness.  相似文献

The Food and Drug Administration (FDA) is amending its new drug and biological product regulations to allow appropriate studies in animals in certain cases to provide substantial evidence of the effectiveness of new drug and biological products used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear substances. This rule will apply when adequate and well-controlled clinical studies in humans cannot be ethically conducted and field efficacy studies are not feasible. In these situations, certain new drug and biological products that are intended to reduce or prevent serious or life-threatening conditions may be approved for marketing based on evidence of effectiveness derived from appropriate studies in animals and any additional supporting data.  相似文献

These final rules make a number of technical revisions to the Listing of Impairments (the listings). We use the listings when you claim benefits based on disability under titles II and XVI of the Social Security Act (the Act). We are making these revisions to reflect advances in medical knowledge, treatment and terminology, to clarify certain criteria in the listings, to remove listings that we rarely use, and to add new listings consistent with current medical practice. We are making these individual technical revisions in order to improve our medical listings and make them easier to understand and use.  相似文献

The Food and Drug Administration (FDA) is amending the medical device tracking regulation. FDA is making substantive changes to revise the scope of the regulation and add certain patient confidentiality requirements, and nonsubstantive changes to remove outdated references and simplify terminology. These revisions are made to conform the regulation to changes made in section 519(e) of the Federal Food, Drug, and Cosmetic Act (the act) by the FDA Modernization Act of 1997 (FDAMA), and to simplify certain requirements.  相似文献

The Food and Drug Administration (FDA) is announcing the availability of a final guidance for industry (#115) entitled "Safety Studies for Veterinary Drug Residues in Human Food: Reproduction Toxicity Testing"(VICH GL22). This final guidance has been adapted for veterinary use by the International Cooperation on Harmonisation of Technical Requirements for Registration of Veterinary Medicinal Products (VICH) from a guidance regarding pharmaceuticals for human use, which was adopted by the International Conference on Harmonisation of Technical Requirements for Approval of Pharmaceuticals for Human Use (ICH). This final VICH guidance document recommends a basic battery of tests that can be used to evaluate the reproduction safety of veterinary drug residues in human food.  相似文献

Section 3102 of the Children's Health Act of 2000, Pub. L. 106-310, amends section 501 of the Public Health Service (PHS) Act (42 U.S.C. 290aa) to add a new subsection (m) entitled "Emergency Response." This newly enacted subsection 501(m) authorizes the Secretary to use up to, but no more than, 2.5% of all amounts appropriated under Title V of the PHS Act, other than those appropriated under Part C, in each fiscal year to make "noncompetitive grants, contracts or cooperative agreements to public entities to enable such entities to address emergency substance abuse or mental health needs in local communities." Because Congress believed the Secretary needed the ability to respond to emergencies, it exempted any grants, contracts, or cooperative agreements authorized under this section from the peer review process. See section 501(m)(1) of the PHS Act. Instead, the Secretary is to use an objective review process by establishing objective criteria to review applications for funds under this authority.  相似文献

The Food and Drug Administration (FDA) is announcing that it has reclassified the polymethylmethacrylate (PMMA) bone cement intended for use in arthroplastic procedures of the hip, knee, and other joints for the fixation of polymer or metallic prosthetic implants to living bone from class III to class II (special controls). The agency is also announcing that it has issued an order in the form of a letter to the Orthopedic Surgical Manufacturers Association (OSMA) reclassifying the device. The special control for the device is a guidance document entitled "Class II Special Controls Guidance Document: Polymethylmethacrylate (PMMA) Bone Cement." The agency is reclassifying this device into class II because special controls, in addition to general controls, would provide reasonable assurance of the safety and effectiveness of the device, and there is sufficient information to establish special controls.  相似文献

The Occupational Safety and Health Administration (OSHA) is revising the hearing loss recording provisions of the Occupational Injury and Illness Recording and Reporting Requirements rule published January 19, 2001 (66 FR 5916-6135), scheduled to take effect on January 1, 2003 (66 FR 52031-52034). This final rule revises the criteria for recording hearing loss cases in several ways, including requiring the recording of Standard Threshold Shifts (10 dB shifts in hearing acuity) that have resulted in a total 25 dB level of hearing above audiometric zero, averaged over the frequencies at 2000, 3000, and 4000 Hz, beginning in year 2003.  相似文献
