Start Preamble

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule.

SUMMARY:

The Food and Drug Administration (FDA) is reclassifying 28 preamendments devices from class III (premarket approval) into class II (special controls). FDA is also identifying the special controls that the agency believes will reasonably ensure the safety and effectiveness of the devices. This reclassification is being undertaken on the agency's own initiative based on new information under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Safe Medical Devices Act of 1990 and the FDA Modernization Act of 1997. The agency is also revising the identification of six of the devices subject to this rule to more accurately reflect the characteristics of devices actually being marketed. FDA is withholding action on 11 devices, which the agency proposed to reclassify, pending further action.

DATES:

This rule is effective May 1, 2000.

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. FDA invited interested persons to comment on the proposed rule by June 14, 1999.

FDA received one request to reopen the comment period for six devices. 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 FDA's Good Guidance Practices (GGP's). The request further said that it was impossible to comment on the Start Printed Page 17139proposed reclassification without the guidance documents being available. Therefore, the requestor asked that FDA extend the comment period until at least 90 days after the guidance documents are publicly available.

FDA agrees with the request. FDA has also identified an additional three devices for which FDA had not issued the guidance documents proposed as special controls in accordance with the GGP policy. Therefore, FDA is withholding action on the devices listed in table 1 of this document at this time. FDA will make the guidance documents for these devices available for comment through the GGP process and will reopen the comment period on the reclassification of these devices when the guidance documents are available.

FDA also received a request for an extension of the comment period for the cutaneous oxygen monitor (§ 868.2500 (21 CFR 868.2500)) on behalf of a foreign manufacturer. The manufacturer needed additional time to translate the proposed special controls documents to prepare their comments. FDA granted this request and will withhold action on this device and reopen the comment period.

II. Comments

FDA received five comments on the proposal. The following is a summary of the comments and FDA's response:

(Comment 1) One comment supported the proposal to reclassify four orthopedic devices: The elbow joint metal/polymer constrained cemented prosthesis (§ 888.3150 (21 CFR 888.3150)), the knee joint patellofemoral polymer/metal semi-constrained cemented prosthesis (§ 888.3540 (21 CFR 888.3540)), the shoulder joint metal/polymer non-constrained cemented prosthesis (§ 888.3650 (21 CFR 888.3650)), and the shoulder joint metal/polymer semi-constrained cemented prosthesis (§ 888.3660 (21 CFR 888.3660)).

FDA agrees with this comment.

(Comment 2) One comment supported the proposed reclassification and special controls for the tinnitus masker (§ 874.3400 (21 CFR 874.3400)).

FDA agrees with this comment.

(Comment 3) A third comment addressed the vascular graft prosthesis of less than 6 millimeters diameter (§ 870.3450).

As noted above, FDA is withholding action on this device, until the proposed guidance document intended to be a special control is made available for comment. FDA will address this comment when it takes final action on this device.

(Comment 4) One manufacturer agreed with the proposal to reclassify the over-the-counter (OTC) denture cushion or pad (§ 872.3540 (21 CFR 872.3540)) but recommended that it be reclassified from class III into class I. The manufacturer submitted data on the device to support the claim that general controls are adequate to provide reasonable assurance of the safety and effectiveness of the device. The comment agreed that proper labeling is important to control risks to health associated with the use of this device.

FDA disagrees with this comment. FDA believes it is necessary that consumers have appropriate directions for use to correctly prepare denture material for a properly fitted denture. The guidance document describes the information necessary to provide reasonable assurance of the safe and effective use of the OTC dental pad or cushion. In particular, it includes descriptive information on the indications for use, contraindications, cautions, and potential adverse effects for the device, as well as the directions for use information regarding adequate mixing, preparation, and use of the product. The guidance document also provides ways that a manufacturer can establish that there is reasonable assurance that an OTC denture cushion or pad with a new intended use, chemical composition, labeling claims, or method of preparation is safe and effective.

(Comment 5) One comment raised three issues concerning the proposed reclassification of the high permeability hemodialysis system (§ 876.5860 (21 CFR 876.5860)) as follows:

1. The comment recommended changing the name and the section heading of § 876.5860 to include three additional therapies: Hemofiltration, hemoconcentration, and hemodiafiltration.

FDA notes that it has cleared these three additional renal therapies identified by the comment under § 876.5860. FDA will not revise the name of the device but it will revise the first sentence of the identification section (§ 876.5860(a)) as follows: “A high permeability hemodialysis system is a device intended for use as an artificial kidney system for treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration.”

2. The comment also recommended further revising the identification of the high permeability hemodialysis system to state that the hemofiltration, hemoconcentration, and hemodiafiltration ultrafiltration coeficient (Kuf) should be changed from “greater than 12 ml/hr/mmHg” to “greater than 8 ml/hr/mmHg”.

FDA agrees with the comment with the provision that the bovine or expired human blood be used to measure the Kuf. In the final rule, § 876.5860(a)(1) is revised to read:

The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (Kuf) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or another method of ultrafiltration control to prevent fluid imbalance.

3. The comment also recommended that any revisions to the hemodialysis-related guidance documents be implemented as Level 1 guidance documents under FDA's GGP's.

FDA will follow its GGP's in issuing revisions to guidance documents used as special controls for this device as well as for all devices.

(Comment 6) FDA also made the following changes on its own initiative for accuracy and clarity:

1. FDA incorrectly cited the title of its biocompatibility guidance and is correcting the title of the guidance to read, “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Devices Part I: Evaluation and Testing’.” Start Printed Page 17140The special control is the FDA guidance document and not the ISO consensus standard itself.

2. In § 874.3930—Tympanostomy tube with semipermeable membrane (21 CFR 874.3930), FDA deleted the proposed special controls except the device specific guidance document. FDA believes that the guidance document adequately addresses the other proposed special controls.

3. In § 876.4480—Electrohydraulic lithotriptor (21 CFR 876.4480), FDA deleted the proposed special controls except the device specific FDA guidance document. FDA believes that the guidance document adequately addresses the other proposed special controls.

4. In § 876.5860—High permeability hemodialysis system, FDA deleted the American National Standards Institute (ANSI)/Association for the Advancement in Medical Instrumentation (AAMI) and United States Pharmacopeia (USP) standards because FDA believes that these standards are adequately addressed in the FDA sterility guidance.

5. In § 884.1060—Endometrial aspirator (21 CFR 884.1060); 21 CFR 884.1110Endometrial brush; and § 884.1185—Endometrial washer (21 CFR 884.1185), FDA clarified the wording of the labeling and design and testing special controls.

6. In § 884.4100—Endoscopic electrocautery and accessories (21 CFR 884.4100), and § 884.4150—Bipolar endoscopic coagulator-cutter and accessories (21 CFR 884.4150), FDA added the complete titles and years of the standards and clarified the labeling and treatment instructions. In the preamble to the proposed rule, FDA identified the sterility guidance as a special control for these two devices but did not include it in the regulatory text. FDA has included the sterility guidance in the regulatory text of the final rule.

7. In some device identifications, FDA made minor editorial changes.

III. FDA's Conclusion

FDA has concluded, based on a review of the available information, that the special controls identified in tables 2 and 3 of this document provide reasonable assurance of the safety and effectiveness of these 28 devices. The two tables summarize the special controls to be applied to each device.

IV. Environmental Impact

The agency has determined under 21 CFR 25.34(b) that this classification action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required.

V. Analysis of Impacts

FDA has examined the impacts of the rule under Executive Order 12866, and the Regulatory Flexibility Act (5 U.S.C 601-612) (as amended by subtitle D of the Small Business Regulatory Fairness Act of 1996 (Public Law 104-121), and the Unfunded Mandates Reform Act of 1995 (Public Law 104-4)). Executive Order 12866 directs agencies to assess all costs and benefits of available regulatory alternatives and, when regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity). The agency believes that this rule is consistent with the regulatory philosophy and principles identified in the Executive Order. In addition, the final rule is not a significant regulatory action as defined by the Executive Order and so is not subject to review under the Executive Order.

The Regulatory Flexibility Act requires agencies to analyze regulatory options that would minimize any significant impact of a rule on small entities. Reclassification of these devices from class III will relieve all manufacturers of these devices of the cost of complying with the premarket approval requirements in section 515 of the act. Moreover, compliance with special controls proposed for these devices will not impose significant new costs on affected manufacturers as most of these devices already comply with the proposed special controls. Because reclassification will reduce regulatory costs with respect to these devices, it will impose no significant economic impact on any small entities, and it may permit small potential competitors to enter the marketplace by lowering their costs. The agency therefore certifies that this rule will not have a significant economic impact on a substantial number of small entities. In addition, this proposed rule will not impose costs of $100 million or more on either the private sector or State, local, and tribal governments in the aggregate, and therefore a summary statement of analysis under section 202(a) of the Unfunded Mandates Reform Act of 1995 is not required.

VI. Paperwork Reduction Act of 1995

FDA concludes that this proposed rule contains no collections of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.

High permeability hemodialysis system.

(a) Identification. A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:

(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (Kuf) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.

(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.).

(3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).

(b) Classification. Class II. The special controls for this device are FDA's:

(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and ­Testing,’ ”

(2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,”
