Implant (medicine) : ウィキペディア英語版 | Implant (medicine)
An implant is a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. Medical implants are man-made devices, in contrast to a transplant, which is a transplanted biomedical tissue. 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. == Applications == Examples of implants are pins, rods, screws, and plates used to anchor fractured bones while they heal. A surgical mesh may be used for tissue support in hernia repair. The implant may be non-resorbable (permanent) or resorbable. Contraceptive implants are used for birth control. A contraceptive implant is a small flexible tube measuring about 40mm in length which is inserted under the skin by a doctor (typically the upper arm). The implant is among the most effective birth control methods.
