AGENCY:

Food and Drug Administration, HHS.

ACTION:

Final rule.

SUMMARY:

The Food and Drug Administration (FDA) is reclassifying the topical oxygen chamber for extremities (TOCE) from class III to class II. This device is intended to surround a patient's limb and apply humidified oxygen topically at a pressure slightly greater than atmospheric pressure to aid healing of chronic skin ulcers, such as bedsores. This reclassification is on the Secretary of Health and Human Services's own initiative based on new information. This action is being taken under the Federal Food, Drug, and Cosmetic Act (the FD&C Act) as amended by the Medical Device Amendments of 1976 (the 1976 Amendments), the Safe Medical Devices Act of 1990 (the SMDA), and the Food and Drug Administration Modernization Act of 1997 (FDAMA). Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document entitled “Class II Special Controls Guidance Document: Topical Oxygen Chamber for Extremities,” which will serve as the special control for this device.

DATES:

This rule is effective May 25, 2011.

SUPPLEMENTARY INFORMATION:

I. Background

The FD&C Act (21 U.S.C. 301 et seq.), as amended by the 1976 Amendments (Pub. L. 94-295), the SMDA (Pub. L. 101-629), and the FDAMA (Pub. L. 105-115), established a comprehensive system for the regulation of medical devices intended for human use. Section 513 of the FD&C Act (21 U.S.C. 360c) established three categories (classes) of devices, depending on the regulatory controls needed to provide reasonable assurance of their safety and Start Printed Page 22806effectiveness. The three categories of devices are class I (general controls), class II (special controls), and class III (premarket approval).

Under section 513 of the FD&C Act, devices that were in commercial distribution before May 28, 1976 (the date of enactment of the 1976 Amendments), generally referred to as preamendments devices, are classified after FDA has: (1) Received a recommendation from a device classification panel (an FDA advisory committee); (2) published the panel's recommendation for comment, along with a proposed regulation classifying the device; and (3) published a final regulation classifying the device. FDA has classified most preamendments devices under these procedures.

Devices that were not in commercial distribution prior to May 28, 1976, generally referred to as postamendments devices, are classified automatically by statute (section 513(f) of the FD&C Act (21 U.S.C. 360c(f)) into class III without any FDA rulemaking process. Postamendment devices remain in class III and require premarket approval, unless the device is reclassified into class I or II, or FDA issues an order finding the device to be substantially equivalent, in accordance with section 513(i) of the FD&C Act (21 U.S.C. 360c(i)), to a predicate device that does not require premarket approval. The agency determines whether new devices are substantially equivalent to predicate devices by means of premarket notification procedures in section 510(k) of the FD&C Act (21 U.S.C. 360(k)) and part 807 of the regulations (21 CFR part 807).

A preamendments device that has been classified into class III may be marketed, by means of premarket notification procedures, without submission of a premarket approval application (PMA) until FDA issues a final regulation under section 515(b) of the FD&C Act (21 U.S.C. 360e(b)) requiring premarket approval.

Section 513(e) of the FD&C Act (21 U.S.C. 360c(e)) governs reclassification of classified preamendments devices. This section provides that FDA may, by rulemaking, reclassify a device based upon “new information.” FDA can initiate a reclassification under section 513(e) of the FD&C Act or an interested person may petition FDA to reclassify a preamendments device. The term “new information,” as used in section 513(e) of the FD&C Act, includes information developed as a result of a reevaluation of the data before the agency when the device was originally classified, as well as information not presented, not available, or not developed at that time. (See, e.g., Holland Rantos v. United States Department of Health, Education, and Welfare, 587 F.2d 1173, 1174 n.1 (DC Cir. 1978); Upjohn v. Finch, 422 F.2d 944 (6th Cir. 1970); Bell v. Goddard, 366 F.2d 177 (7th Cir. 1966)).

Reevaluation of the data previously before the agency is an appropriate basis for subsequent regulatory action where the reevaluation is made in light of newly available regulatory authority (see Bell v. Goddard, supra, 366 F.2d at 181; Ethicon, Inc. v . FDA, 762 F. Supp. 382, 389-91 (D.D.C. 1991)), or in light of changes in “medical science.” (See Upjohn v. Finch, supra, 422 F.2d at 951). Regardless of whether data before the agency are past or new data, the “new information” to support reclassification under section 513(e)(1) of the FD&C Act must be “valid scientific evidence,” as defined in section 513(a)(3) of the FD&C Act (21 U.S.C. 360c(a)(3)) and 21 CFR 860.7(c)(2). (See, e.g., General Medical Co. v . FDA, 770 F.2d 214 (DC Cir. 1985); Contact Lens Assoc. v. FDA, 766 F.2d 592 (DC Cir.), cert. denied, 474 U.S. 1062 (1985)). FDA relies upon “valid scientific evidence” in the classification process to determine the level of regulation for devices. For the purpose of reclassification, the valid scientific evidence upon which the agency relies must be publicly available. Publicly available information excludes trade secret and/or confidential commercial information, e.g., the contents of a pending PMA. (See section 520(c) of the FD&C Act (21 U.S.C. 360j(c)).

In accordance with section 513(e) of the FD&C Act and 21 CFR 860.130(b)(1), based on new information with respect to the device, FDA, on its own initiative, is reclassifying this device from class III to class II.

II. Regulatory History of the Device

As discussed in the proposed rule, the agency issued a final rule classifying this device into class III (53 FR 23856, June 24, 1988). In August 1997, in response to FDA's order for the submission of information on the TOCE, two manufacturers submitted 515(i) summaries of safety and effectiveness information to the agency for the TOCE. FDA referred the 515(i) submissions to the General and Plastic Surgery Devices Panel (GPS Panel) for their recommendation on the requested reclassification. At a public meeting on November 17, 1998, the GPS Panel recommended that the device be retained in class III.

Since the 1998 GPS Panel meeting, three studies (two prospective and one retrospective) reported safe use and adequate healing of wounds using the TOCE. In addition, FDA has evaluated more than 20 years of clinical experience with the device and the agency's Medical Device Reports, and has found sufficient information to determine the risks to health associated with the use of this device and develop appropriate special controls.

As a result, in the Federal Register of April 6, 2006 (71 FR 17390), FDA proposed to reclassify the TOCE device from class III to class II. The device is intended to surround a patient's limb and apply humidified oxygen topically at a pressure slightly greater than atmospheric pressure to aid healing of chronic skin ulcers such as bedsores. Elsewhere in the Federal Register of April 6, 2006 (71 FR 17476), FDA announced the availability of the draft guidance document entitled “Class II Special Controls Draft Guidance Document: Topical Oxygen Chamber for Extremities,” which FDA intended to serve as the special control for this device type following the effective date of the final reclassification rule.

Interested persons were invited to comment until July 5, 2006, on the proposed regulation and special controls draft guidance document.

III. Analysis of Comments and FDA's Response

FDA received 11 comments on the proposed rule. The comments received discussed academic literature, clinical experiences, and patient outcomes that support the proposed reclassification's determinations of the safety and effectiveness of the TOCE device. The comments did not recommend any changes to the proposed regulation.

IV. Summary of Final Rule

Based on the information discussed in the preamble to the proposed rule, the comments on the proposed rule, a review of the Manufacturer and User Facility Device Experience (MAUDE) database, and a review of current scientific literature, FDA concludes that special controls, in conjunction with general controls, will provide reasonable assurance of the safety and effectiveness of TOCE. The agency is, therefore, reclassifying TOCE from class III (premarket approval) into class II (special controls) and issuing a final rule that revises 21 CFR 878.5650. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document entitled “Class II Special Controls Guidance Document: Topical Oxygen Chamber for Extremities,” which will serve as the special control for this device. Following the effective date of this final classification rule, any firm Start Printed Page 22807submitting a 510(k) premarket notification for a TOCE will need to address the issues covered in the special controls 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.

Section 510(m) of the FD&C Act (21 U.S.C. 360(m)) provides that FDA may exempt a class II device from the premarket notification requirements under section 510(k) of the FD&C Act if FDA determines that premarket notification is not necessary to provide reasonable assurance of the safety and effectiveness of the device. FDA has determined that premarket notification is necessary to provide reasonable assurance of the safety and effectiveness of the TOCE and, therefore, this device type is not exempt from premarket notification requirements.

V. Environmental Impact

The agency has determined under 21 CFR 25.34(b) that this reclassification 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.

VI. Analysis of Impacts

FDA has examined the impacts of the final rule under Executive Order 12866 and the Regulatory Flexibility Act (5 U.S.C. 601-612), and the Unfunded Mandates Reform Act of 1995 (Pub. L. 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 final rule is not a significant regulatory action 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. Because the final rule reclassifying this device from class III to class II will relieve all manufacturers of the device of the cost of complying with the premarket approval requirements of section 515 of the FD&C Act, 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, and the agency certifies that the final rule will not have a significant economic impact on a substantial number of small entities.

Section 202(a) of the Unfunded Mandates Reform Act of 1995 requires that agencies prepare a written statement, which includes an assessment of anticipated costs and benefits, before proposing “any rule that includes any Federal mandate that may result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more (adjusted annually for inflation) in any one year.” The current threshold after adjustment for inflation is $135 million, using the most current (2009) Implicit Price Deflator for the Gross Domestic Product. FDA does not expect this final rule to result in any 1-year expenditure that would meet or exceed this amount.

VII. Federalism

FDA has analyzed this final rule in accordance with the principles set forth in Executive Order 13132. Section 4(a) of the Executive order requires agencies to “construe * * * a Federal statute to preempt State law only where the statute contains an express preemption provision or there is some other clear evidence that the Congress intended preemption of State law, or where the exercise of State law conflicts with the exercise of Federal authority under the Federal statute.” Federal law includes an express preemption provision that preempts certain State requirements “different from or in addition to” certain Federal requirements applicable to devices. (See section 521 of the FD&C Act (21 U.S.C. 360k); Medtronic Inc., v. Lohr, 518 U.S. 470 (1996); Riegel v. Medtronic Inc., 128 S. Ct. 999 (2008)). The special controls established by this final rule create “requirements” for specific medical devices under 21 U.S.C. 360k, even though product sponsors have some flexibility in how they meet those requirements. See Papike v. Tambrands, Inc., 107 F.3d 737, 740-742 (9th Cir. 1997).

VIII. Paperwork Reduction Act of 1995

This final rule contains no collections of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3520) is not required. FDA concludes that the special controls guidance document identified by this rule contains information collection provisions that are subject to review and clearance by OMB under the PRA.

Elsewhere in this issue of the Federal Register, FDA is publishing a notice announcing the availability of the guidance document entitled, “Class II Special Controls Guidance Document: Topical Oxygen Chamber for Extremities.” The notice contains an analysis of the paperwork burden for the guidance.
