Indications for Use

The products c-max and s-max offer motorized stair-climbing support for disabled seated persons to move from one level to another with or without manual wheelchair adaption.

Device Story

The c-max and s-max are motorized stair-climbing devices designed to transport disabled seated individuals between levels. The system consists of a climbing unit with a motor, battery pack, main wheels, and a climbing foot mechanism. The device is operated by an attendant who controls the unit via a handle-mounted control panel. The motor drives the climbing mechanism to ascend or descend stairs step-by-step. The c-max includes an integrated seat, while the s-max is designed for use with manual wheelchairs. The device provides mobility assistance in various environments, reducing the physical burden on the attendant and enabling patient movement across stairs. The system is powered by sealed lead-acid batteries and features adjustable climbing speeds and safety brakes.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design, performance standards (EN 12182, ISO 7176 series), and comparison to the predicate device.

Technological Characteristics

Motorized stair-climbing system; 24V DC motor (178W-275W); 2x12V sealed lead-acid batteries; adjustable climbing speed (8-23 steps/min); max step height 21-25.5cm; max load 120-160kg. Materials: seat material compliant with DIN EN ISO 10993-5. Standards: EN 12182, ISO 7176-14, ISO 7176-16, ISO 7176-21, ISO 7176-23. Connectivity: None. Sterilization: N/A.

Indications for Use

Indicated for disabled seated persons with ambulatory impairments, including spinal cord injury, spina bifida, cerebral palsy, multiple sclerosis, muscular dystrophy, polio, and rheumatism, to assist in moving between levels with or without manual wheelchair adaptation.

Regulatory Classification

Identification

Powered patient stairway chair lifts: A powered patient stairway chair lift is a motorized lift equipped with a seat and permanently mounted in one location that is intended for use in mitigating mobility impairment caused by injury or other disease by moving a person up and down a stairway. All other powered patient transport: A powered patient transport is a motorized device intended for use in mitigating mobility impairment caused by injury or other disease by moving a person from one location or level to another, such as up and down flights of stairs (e.g., attendant-operated portable stair-climbing chairs). This generic type of device does not include motorized three-wheeled vehicles or wheelchairs.

Special Controls

(i) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized edition of American Society of Mechanical Engineers (ASME) A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must demonstrate that the safety controls are adequate to prevent a free fall of the chair in the event of a device failure; (ii) Appropriate analysis and nonclinical testing must demonstrate the ability of the device, including armrests, to withstand the rated load with an appropriate factor of safety; (iii) Appropriate restraints must be provided to prevent the user from falling from the device (such as that outlined in the currently FDA-recognized edition of ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”); (iv) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized editions of AAMI/ANSI/IEC 60601-1-2, “Medical Electrical Equipment—Part 1-2: General Requirements for Safety—Collateral Standard: Electromagnetic Compatibility—Requirements and Tests,” and ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must validate electromagnetic compatibility and electrical safety; and (v) Appropriate analysis and nonclinical testing must demonstrate the resistance of the device upholstery to ignition.

Dear Mrs. Bankston:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act

or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21

CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please go to http://www.fda.gov/AboutFDA/CentersOffices/CDRH/CDRHOffices/ucm115809.htm for the Center for Devices and Radiological Health's (CDRH's) Office of Compliance. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR) Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to

http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
