An implant is a medical device manufactured to replace a missing biological structure, to support a damaged biological structure, or to enhance an existing biological structure.
Medical implants are man-made devices.
In contrast to a transplant, which is a transplanted biomedical tissue, implants are materials that are not live. The surface of implants that contact the body might be made of a biomedical material such as titanium, silicone or apatite depending on what is the most functional. In some cases implants contain electronics e.g. artificial pacemaker and cochlear implants.
Some implants are bioactive, such as subcutaneous drug delivery devices in the form of implantable pills or drug-eluting stents.
An orthopedic implant is a medical device manufactured to replace a missing joint or bone or to support a damaged bone. An orthopedic implant is a structure submitted to forces responsible for its possible failure. Self-protective smart devices are an example of the next generation of orthopedic implants.
This new technology has the potential to eliminate periprosthetic infection, a major and growing problem in orthopedic practice.
A smart implant is to measure the specific information and translate into a signal for decision making process. Smart orthopedic implants can provide real-time feedback to physicians or patients on how the implants are performing, what is happening inside a bone or joint, or if a patient has exceeded the device’s optimal range of motion.
