Prosthetic (Prosthesis) devices, such as an artificial leg, that replace a part of the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include artificial eyes, palatal obturator, gastric bands, and dentures.
A research team combining high-energy physicists from the University of California, Santa Cruz, and neuroscientists from the Salk Institute in La Jolla, Calif., has discovered a type of retinal cell that may help monkeys, apes, and humans see motion.
MIT researchers have developed a new algorithm to help create prosthetic devices that convert brain signals into action in patients who have been paralyzed or had limbs amputated.
Compared to advancements in modern medicine over the past 70 years, there have been few new treatment options for people who stutter.
Decoding the complex electrical signals that brain cells use to "talk" to each other is a new and important frontier in neuroscience, one that could revolutionize the diagnosis and treatment of neurological and psychiatric disease.
In Medicine, paracetamol is used to soothe every kind of pain, from simple molar pain to pain produced by bone fractures.
Today valve disease still represents an important health problem; valve patients are getting older and older with more and more comorbities, which contribute to increased operative risk and render the decision-making process more difficult.
A team of Mayo Clinic researchers has discovered a new, more accurate diagnostic test to detect infection of prosthetic joints, potentially leading to better treatment options and patient outcomes.
Hearing and balance experts at Johns Hopkins report successful testing in animals of an electrical device that partly restores a damaged or impaired sense of balance.
Athough most artificial joints resemble the shape and structure of the joint they're designed to replace, one new prosthesis - the reverse shoulder - takes a different approach, reversing the position of the normal ball-and-socket design.
In the world of prosthetic hips, what was old is new again. A procedure known as hip resurfacing, once tried two to three decades ago, is experiencing a resurgence in the U.S., thanks to improved technology.
Imagine a chip, strategically placed in the brain, that could prevent epileptic seizures or allow someone who has lost a limb to control an artificial arm just by thinking about it.
The neck and arm pain caused by degenerative cervical (neck) disc disease may be eliminated by replacing the problem disc with a metal-on-metal artificial disc, said Loyola University Health System neurological surgeon Dr. Russ P. Nockels.
Back pain can interfere with normal activities. One of the most common causes is degenerative disk disease. Fortunately, there is help.
The Stanford University Program in Biodesign is partnering with the government of India to establish a new training program, called Stanford-India Biodesign, to help create the next generation of biomedical technology innovators in India.
Researchers at the University at Buffalo and Roswell Park Cancer Institute have shown for the first time that an association exists between long-standing periodontitis, or gum disease, and risk of tongue cancer.
It took only seconds for the Humvee to flip over and crash on a highway near Camp Bucca in southern Iraq in August 2005.
Researchers at Arizona State University's Polytechnic campus and the Military Amputee Research Program at Walter Reed Army Medical Center are teaming up to create the next generation of powered prosthetic devices based on lightweight energy storing springs.
An international team led by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., has developed a prototype of the first fully integrated prosthetic arm that can be controlled naturally and provide sensory feedback, and allows for eight degrees of Freedom -- a level of control far beyond the current state of the art for prosthetic limbs.
Taking a precautionary antibiotic before a trip to the dentist isn't necessary for most people, and in fact, might create more harm than good, according to updated recommendations from the American Heart Association.
Scientists are working now to create novel nanostructures that serve as new kinds of drugs for treating cancer, Parkinson's and cardiovascular disease; to engineer nanomaterials for use as artificial tissues that would replace diseased kidneys and livers, and even repair nerve damage; and to integrate nanodevices with the nervous system to create implants that restore vision and hearing, and build new prosthetic limbs.
