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.
Research at Arizona State University and Columbia University to better understand the intricate sensory and cognitive connections between the brain and the hands has won support from the National Science Foundation. New discoveries about such connections could benefit people with neurological disorders such as Parkinson's disease and cerebral palsy, and those who need prosthetic hands.
If heart valves don't close properly, they are replaced. Conventional treatment of venous valve failure, however, has up to now always and exclusively been via medication. In future, an implant will assume the function of damaged valves - and a new dispensing tool means these prostheses can be made using an automated process.
Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought.
Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry lab, have been working on ways to improve amputees' control over prosthetics with direct help from their own nervous systems.
More than 4 million Americans over 50 have artificial knees, according to a new study. ... "These data are sobering because we didn't know what an army of people we've created over the last decade," said study author Elena Losina, co-director of the Orthopedics and Arthritis Center for Outcomes Research at Harvard's Brigham and Women's Hospital. ... Artificial knees also wear out after a period of time, so as the operations are increasingly done on younger Americans, many will live long enough to almost certainly need a second or even third knee replacement.
Today's early morning highlights from the major news organizations preview President Barack Obama's budget, which will be released today, and examine the lingering controversy over mandates on contraceptive coverage.
"Grand Challenges Canada on Thursday announced 15 grants valued in total at more than $1.5 million awarded to some of Canada's most creative innovators from across the country in support of their work to improve global health conditions," according to a press release from the Sandra Rotman Centre for Global Health, which hosts Grand Challenges.
Ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory.
In a medical breakthrough, doctors and bio-engineers have collaborated
Scientists at the University of California at Berkeley have devised a method by which they can hear thoughts. They conducted a small study in which they could predict what people were thinking based on their brain activity.
VisionCare Ophthalmic Technologies, Inc., a developer of advanced visual prosthetic devices for the treatment of end-stage age-related macular degeneration (AMD), today announced the closing of expansion of the Series E financing, with Agate Medical Investments leading the expansion round. Agate's Managing General Partner, Chanan Schneider, will join the VisionCare team as a board observer.
As part of a White House effort to ensure that America's military heroes receive care worthy of their service, the UCLA Health System and the David Geffen School of Medicine at UCLA have pledged to mobilize their uniquely integrated missions in education, research and clinical care to help train physicians to meet the special needs of veterans, active service members and their families.
In a moving scene, the President of The Disabled Veterans National Foundation (www.dvnf.org ) and Michael McNaughton - a combat soldier who lost his leg on a mission in Afghanistan- delivered Gift Cards to veterans who are patients in the amputee wing at Walter Reed National Military Medical Center in Bethesda, MD over the holidays.
Other than Olympic race walkers, people generally find it more comfortable to run than walk when they start moving at around 2 meters per second - about 4.5 miles per hour.
A team of engineers and physicians have made a surprising discovery that offers a target for designing new materials for hip implants that are less susceptible to the joint's normal wear and tear.
Scientists at University College Dublin, Ireland, have identified a genetic alteration which causes a child to be born with no eyes - a condition called anophthalmia.
The state needs to train or recruit an additional 100 physicians a year through 2030 to meet the projected demand for health care, according to a new Wisconsin Hospital Association report. ... The group says the state must act immediately ... Primary care physicians - doctors who specialize in family and internal medicine and pediatrics - will account for 80 percent of the projected shortage.
A drug-coated balloon inserted in a narrowed bare metal stent is a promising therapy for restoring blood flow, according to research presented at the American Heart Association's Scientific Sessions 2011.
For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.
A plastic surgeon at UT Southwestern Medical Center recently used a novel technique to save the arm of a Gulf War veteran who was rushed to Parkland Memorial Hospital after a horrific accident.
