Medical Device Definition
An instrument, apparatus, implement, machine, contrivance,
implant, in vitro reagent, or other similar or related article, including
a component part, or accessory which is:
-Intended for use in the diagnosis of disease or
other conditions
-Intended to affect the structure or any function
of the body of man or other animals

15. LATEST ADVANCEMENT
• Each leg is fitted with a Bluetooth device.
• Bluetooth is more often recognized for its ability to connect pieces of
technology together without the use of wires. Bleill’s case, the
Bluetooth devices communicate with each other to regulate stride,
pressure and speed in the prosthetic legs.

16. LATEST ADVANCEMENT
• With an onboard computer within the prosthesis, people with above-
knee amputations have greater control over walking, stopping and
moving on inclines. These “robotic” knees, termed microprocessor
knees, analyze the pressure an amputee puts on the missing limb.
Also contained within the knee is a fluid control unit, which the
microprocessor monitors to appropriate joint resistance when walking
on inclines.
