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
IMD
Applications
Technique: Total Hip ReplacementTechnique: Total Hip Replacement
Femoral neck Femoral neck resectionresection
The ball and socket components are made of metal. These metal implants have been used in total hip replacement surgeries

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.
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.
