The device operates via an integrated electric motor mechanism controlled by the user to lift and recline the chair frame. It is intended for use in home or clinical settings by the patient. The device provides mechanical assistance to reduce the physical effort required for standing, thereby promoting patient independence and mobility.

Clinical Evidence

Bench testing only.

Technological Characteristics

Motorized lift and recline mechanism; electric power source; furniture-based form factor.

Indications for Use

Indicated for aged or partially disabled individuals requiring assistance transitioning from a seated to a standing position.

Regulatory Classification

Identification

An electric positioning chair is a device with a motorized positioning control that is intended for medical purposes and that can be adjusted to various positions. The device is used to provide stability for patients with athetosis (involuntary spasms) and to alter postural positions.

Special Controls

(1) Appropriate analysis and non-clinical testing must demonstrate that the safety controls are adequate to ensure safe use of the device and prevent user falls from the device in the event of a device failure; (2) Appropriate analysis and non-clinical testing must demonstrate the ability of the device to withstand the rated user weight load with an appropriate factor of safety; (3) Appropriate analysis and non-clinical testing must demonstrate the longevity of the device to withstand external forces applied to the device and provide the user with an expected service life of the device; (4) Appropriate analysis and non-clinical testing must demonstrate proper environments of use and storage of the device to maximize the longevity of the device; (5) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of ANSI/AAMI/ES60601-1, “Medical Electrical Equipment—Part 1: General Requirements for Basic Safety and Essential Performance,” and ANSI/AAMI/IEC 60601-1-2, “Medical Electrical Equipment—Part 1-2: General Requirements for Basic Safety and Essential Performance—Collateral Standard: Electromagnetic Disturbances—Requirements and Tests”) must validate electromagnetic compatibility and electrical safety; (6) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of ANSI/AAMI/ISO 10993-1, “Biological Evaluation of Medical Devices—Part 1: Evaluation and Testing Within a Risk Management Process,” ANSI/AAMI/ISO 10993-5, “Biological Evaluation of Medical Devices—Part 5: Tests for In Vitro Cytotoxicity,” and ANSI/AAMI/ISO 10993-10, “Biological Evaluation of Medical Devices—Part 10: Tests for Irritation and Skin Sensitization”) must validate that the skin-contacting components of the device are biocompatible; (7) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of IEC 62304, “Medical Device Software—Software Life Cycle Processes”) must validate the software life cycle and that all processes, activities, and tasks are implemented and documented; (8) Appropriate analysis and non-clinical testing must validate that the device components are found to be non-flammable; (9) Appropriate analysis and non-clinical testing must validate that the battery in the device (if applicable) performs as intended over the anticipated service life of the device; and (10) Adequate patient labeling is provided to the user to document proper use and maintenance of the device to ensure safe use of the device by the patient in the intended use environment.

Dear Mr. Whitaker:

We have reviewed your Section 510(k) notification of intent to market the device referenced above, and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General Regulation (21 CFR Part 820), and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
