Breast Implant
A breast implant is a prosthesis used to change the size, shape, and contour of a person's breast. In reconstructive plastic surgery, breast implants can be placed to restore a natural looking breast following a mastectomy, to correct congenital defects and deformities of the chest wall or, cosmetically, to enlarge the appearance of the breast through breast augmentation surgery. Complications of implants may include breast pain, rashes, skin changes, infection, rupture, cosmetic changes to the breasts such as asymmetry and hardness, and a fluid collection around the breast. The most serious complication is a type of lymphoma (cancer of the immune system) known as Breast Implant Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). There are four general types of breast implants, defined by their filler material: saline solution, silicone gel, structured and composite filler. The saline implant has an elastomer silicone shell filled with sterile saline solution during surge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochlear Implant
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound. The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children. This component, the sound processor, contains microphones, electronics that include digital signal processor (DSP) chips, battery, and a coil that transmits a signal to the implant across the skin. The inside component, the actual implant, has a coil to receive signals, electronics, and an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Implant
A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown. Success or failure of implants depends on the health of the person receiving the treatment, drugs which affect the chances of osseointegration, and the health of the tissues in the mouth. The amount of stress that will be put on the impla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microchip Implant (human)
A human microchip implant is any electronic device implanted subcutaneously (subdermally) usually via an injection. Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number that can be linked to information contained in an external database, such as identity document, criminal record, medical history, medications, address book, and other usage. History * 1998 - The first experiments with a radio-frequency identification (RFID) implant were carried out in 1998 by the British scientist Kevin Warwick. His implant was used to open doors, switch on lights, and cause verbal output within a building. After nine days the implant was removed and has since been held in the Science Museum in London. * 2004 - March 18, 2004 - Nokia, Philips (now under NXP Semiconductors) and Sony established the NFC Forum, a non-profit industry formed to advance th ...

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 Organ transplant, transplant, which is a transplanted biomedical tissue. The surface of implants that contact the body might be made of a Biomaterial, 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 Biological activity, bioactive, such as Subcutaneous tissue, subcutaneous drug delivery devices in the form of implantable pills or drug-eluting stents. Applications Implants can roughly be categorized into groups by application: Sensory and neurological Perception, Sensory and Neurotechnology#Implant technologies, neurological implants are used for disorders affecting the major senses and the br ...

Osseointegration
Osseointegration (from Latin ''osseus'' " bony" and ''integrare'' "to make whole") is the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant ("load-bearing" as defined by Albrektsson et al. in 1981). A more recent definition (by Schroeder et al.) defines osseointegration as "functional ankylosis (bone adherence)", where new bone is laid down directly on the implant surface and the implant exhibits mechanical stability (i.e., resistance to destabilization by mechanical agitation or shear forces). Osseointegration has enhanced the science of medical bone and joint replacement techniques as well as dental implants and improving prosthetics for amputees. Definitions Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which oste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Implantable Cardioverter-defibrillator
An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. "AICD" was trademarked by the Boston Scientific corporation, so the more generic "ICD" is preferred terminology. Current device batteries last about six to ten years; with advances in technology (batteries with more capacity or potentially rechargeable batteries) it may be possible to increase this well past ten years. The lead (the electrical cable connecting the device to the heart) has a much longer average longevity but can incur various types of malfunction, specifically insulation failure or fracture of the conductor, and require replacement. The process o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subdermal Implant
A subdermal implant refers to a body modification that is placed underneath the skin, therefore allowing the body to heal over the implant and creating a raised design. Such implants fall under the broad category of body modification. Many subdermal implants are made out of silicone, either carved or mold injected. Many people who have subdermal implants use them in conjunction with other types of body modification to create a desired, dramatic effect. This process is also known as a ''3-D implant'', or ''pocketing''. History The first subdermal implant was implanted in 1994. It is generally agreed upon that they were pioneered by Steve Haworth. In his shop, HTC Body Piercing, in Phoenix, Arizona, he first began these procedures after being asked for a bracelet. He concluded that he could put a row of beads under the woman's wrist to create the effect she desired. This was followed in 1998 by the scientist Kevin Warwick who experimented with both an RFID and an electrode array im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain Implant
Brain implants, often referred to as neural implants, are technological devices that connect directly to a biological subject's brain – usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain that have become dysfunctional after a stroke or other head injuries. This includes sensory substitution, e.g., in vision. Other brain implants are used in animal experiments simply to record brain activity for scientific reasons. Some brain implants involve creating interfaces between neural systems and computer chips. This work is part of a wider research field called brain–computer interfaces. (Brain–computer interface research also includes technology such as EEG arrays that allow interface between mind and machine but do not require direct implantation of a device.) Neural implants such as deep brain stimul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinal Implant
Retinal prostheses for restoration of sight to patients blinded by retinal degeneration are being developed by a number of private companies and research institutions worldwide. The system is meant to partially restore useful vision to people who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD). Three types of retinal implants are currently in clinical trials: epiretinal (on the retina), subretinal (behind the retina), and suprachoroidal (between the choroid and the sclera). Retinal implants introduce visual information into the retina by electrically stimulating the surviving retinal neurons. So far, elicited percepts had rather low resolution, and may be suitable for light perception and recognition of simple objects. History Foerster was the first to discover that electrical stimulation of the occipital cortex could be used to create visual percepts, phosphenes. The first application of an im ...

Contraceptive Implant
A contraceptive implant is an implantable medical device used for the purpose of birth control. The implant may depend on the timed release of hormones to hinder ovulation or sperm development, the ability of copper to act as a natural spermicide within the uterus, or it may work using a non-hormonal, physical blocking mechanism. As with other contraceptives, a contraceptive implant is designed to prevent pregnancy, but it does not protect against sexually transmitted infections. Women Implant The contraceptive implant is hormone-based and highly effective, approved in more than 60 countries and used by millions of women around the world. The typical implant is a small flexible tube measuring about 40mm in length. It is most commonly inserted subdermally in the inner portion of the upper, non-dominant arm by a trained and certified health care provider. After insertion, it prevents pregnancy by releasing progestin which inhibits ovulation. The two most common versions are the ...

List Of Orthopedic Implants
An orthopedic implant is a medical device manufactured to replace a missing joint or bone or to support a damaged bone. The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone. During the surgery of broken bones through internal fixation the bone fragments are first reduced into their normal alignment then they are held together with the help of internal fixators such as plates, screws, nails, pins and wires. Eponymous implants and their uses * Austin-Moore prosthesis for fracture of the neck of femur * Baksi's prosthesis for elbow replacement * Charnley prosthesis for total hip replacement * Condylar blade plate for condylar fractures of femur * Ender's nail for fixing intertrochanteric fracture * Grosse-Kempf nail for tibi ...
