The description focuses on mechanical and electronic modifications, including replacing discrete logic with a microprocessor, but there is no mention of AI or ML algorithms, data processing, or learning capabilities.
No.
The device's intended use is to transfer a patient, not to provide therapy or treatment for a disease or condition.
No
The device description indicates its purpose is to physically transfer patients, and it does not mention any function related to diagnosing medical conditions.
No
The device description clearly outlines a physical system consisting of a bed, wheelchair, and footrest attachment with various mechanical and electronic components, including motors, rollers, and a microprocessor. While there is a mention of replacing discrete logic with a microprocessor, the core functionality and description are centered around hardware.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as "to transfer a patient from or to the bed." This is a physical transfer of a patient.
- Device Description: The description details a system of a bed, wheelchair, and footrest used for patient transfer. It describes mechanical and electronic components involved in moving the patient.
- Lack of IVD Characteristics: There is no mention of:
- Analyzing biological samples (blood, urine, tissue, etc.).
- Providing information about a patient's health status, diagnosis, or treatment based on in vitro analysis.
- Reagents, assays, or laboratory procedures.
The device is a patient transfer system, which falls under the category of medical devices used for physical assistance and mobility, not in vitro diagnostics.

Device Description
The cleared model of the Novabed System, which consists of a bed, a wheelchair, and a footrest attachment, is used to transfer a patient from or to a bed. The bed has a conveyor sheet which is pulled by rollers towards the foot of the bed during a patient transfer from the bed and towards the head of the bed during patient transfer to the bed. Each end of the conveyor sheet is connected to a motorized roller at each end of the bed. During transfer, the patient is moved to the end of the bed and, when partially on the pivoted wheelchair seat and legrest and partially on the bed, the patient is elevated to a vertical sitting position by the elevation of the bed against which the patient's back is resting. As the patient is elevated to a sitting position by the bed, the wheelchair automatically pivots until the seat is horizontal and the legrest vertical. The transfer is complete when the attendant disconnects the wheelchair from the bed and mounts the backrest to the wheelchair.
Nova is seeking clearance to modify the cleared Novabed System and market four models of the device with the modifications. Nova intends to make the following modifications to the cleared Novabed System: (1) integrate the tilt table's footrest into the bed; (2) replace the discrete logic in the bed's electronic control unit with a microprocessor; (3) replace the motor used to automatically pivot the wheelchair ("the pivot motor") with a lever that an attendant can use to manually pivot the wheelchair: (4) replace the pivot motor and linkage mounted on the wheelchair with a motor and draw-bar mounted on the bed; (5) replace the wire cable driven by a linear actuator with a parallel linkage with a cantilever driven by a linear actuator to raise or lower the bed; (6) replace the wire cable that is used to create a data link between the bed and wheelchair with optical couplers; and (7) replace circuits in the sheet motor with reversible motor drive circuitry.

Substantial Equivalence
The cleared model of the Novabed System, which consists of a bed, a wheelchair, and a footrest attachment, is used to transfer a patient from or to a bed. The bed has a conveyor sheet which is pulled by rollers towards the foot of the bed during a patient transfer from the bed and towards the head of the bed during patient transfer to the bed. Each end of the conveyor sheet is connected to a motorized roller at each end of the bed. During transfer, the patient is moved to the end of the bed and, when partially on the pivoted wheelchair seat and legrest and partially on the bed, the patient is elevated to a vertical sitting position by the elevation of the bed against which the patient's back is resting. As the patient is elevated to a sitting position by the bed, the wheelchair automatically pivots until the seat is horizontal and the legrest vertical. The transfer is complete when the attendant disconnects the wheelchair from the bed and mounts the backrest to the wheelchair.
Nova is seeking clearance to modify the cleared Novabed System and market four models of the device with the modifications. Nova intends to make the

following modifications to the cleared Novabed System: (1) integrate the tilt table's footrest into the bed; (2) replace the discrete logic in the bed's electronic control unit with a microprocessor; (3) replace the motor used to automatically pivot the wheelchair ("the pivot motor") with a lever that an attendant can use to manually pivot the wheelchair: (4) replace the pivot motor and linkage mounted on the wheelchair with a motor and draw-bar mounted on the bed; (5) replace the wire cable driven by a linear actuator with a parallel linkage with a cantilever driven by a linear actuator to raise or lower the bed; (6) replace the wire cable that is used to create a data link between the bed and wheelchair with optical couplers; and (7) replace circuits in the sheet motor with reversible motor drive circuitry.
The modified models of the Novabed System have the same intended use as the cleared Novabed System: to transfer a patient to or from the bed. They also have equivalent principles of operation and technological characteristics as they use a conveyor sheet to pull the patient along the bed to a footrest that functions as a tilt table or wheelchair with a footrest that is attached to a bed and they pivot the wheelchair to align it with the bed for patient transfer. The minor technological differences between certain modified models of the device and the cleared Novabed System namely, the integration of the footrest, the attachment of the wheelchair pivot motor to the bed and the use of different linkage, the use of a parallel linkage with a cantilever, the use of an optical coupler, the use of a handheld lever to pivot the wheelchair, and the use of reversible motor drive circuitry in the sheet motor, do not raise new questions of safety or effectiveness. In addition.

the software verification and validation demonstrate that the use of the microprocessor does not raise any new questions of safety or effectiveness. Thus, the modified models of the Novabed System are substantially equivalent to the cleared Novabed System.
