The device description and performance studies focus on the mechanical and structural properties of a manual wheelchair, with no mention of AI or ML technologies.
No
Explanation: The device is described as a manual mechanical wheelchair intended for mobility and transport, not for treating or diagnosing a medical condition.
No
The device is a manual mechanical wheelchair intended for mobility, not for diagnosis. Its purpose is to transport individuals within a healthcare facility.
No
The device description clearly outlines a physical, manually operated wheelchair constructed from aluminum tubing with wheels and casters. There is no mention of any software component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The MR4500 is a manual mechanical wheelchair. Its purpose is to provide mobility to a person. It does not perform any tests on biological samples.
- Intended Use: The intended use clearly states it's for providing mobility as a transport chair within a healthcare facility.
- Device Description: The description details the physical components of a wheelchair (frame, wheels, casters, handles).
- Lack of IVD Indicators: There is no mention of analyzing samples, detecting biomarkers, or any other activity related to in vitro testing.
The information provided describes a medical device used for patient transport, not for diagnostic testing.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The MR4500 passed a 24 hour sustained 100% overload test, a determination of Strength.
The MR4500 has been tested and data provided for 7.0, 3.0 and 1.5 T MR systems environments. The magnetic field strength and magnetic field spatial gradient data showed that no magnetically induced displacement force was produced in the MR4500 up to and including 7.0T MR system. The MR4500 meets the ASTM F2503-8 requirements to be labeled MR Conditional up to and including 7.0T.
