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.
Each fingertip has more than 3,000 touch receptors, which largely respond to pressure. Humans rely heavily on sensation in their fingertips when manipulating an object. The lack of this sensation presents a unique challenge for individuals with upper limb amputations.
Stimulation of the nervous system with neurotechnology has opened up new avenues for treating human disorders, such as prosthetic arms and legs that restore the sense of touch in amputees, prosthetic fingertips that provide detailed sensory feedback with varying touch resolution, and intraneural stimulation to help the blind by giving sensations of sight.
When someone bumps their elbow against a wall, they not only feel pain but also might experience bruising. Robots and prosthetic limbs don't have these warning signs, which could lead to further injury.
People with end-stage renal disease often undergo hemodialysis, a life-sustaining blood-filtering treatment.
Using a new 3D printing process, University of Nottingham researchers have discovered how to tailor-make artificial body parts and other medical devices with built-in functionality that offers better shape and durability, while cutting the risk of bacterial infection at the same time.
Researchers at the University of East Anglia have made an astonishing discovery about how our brains control our hands.
Maintenance of good oral health is more important than use of antibiotics in dental procedures for some heart patients to prevent a heart infection caused by bacteria around the teeth, according to a new American Heart Association scientific statement published today in the association's flagship journal, Circulation.
Researchers from London South Bank University (LSBU) are leading an international project aimed at reducing bacterial infection during the surgical process of medical implants.
A recent case study from North Carolina State University and the University of North Carolina at Chapel Hill demonstrates that, with training, neural control of a powered prosthetic ankle can restore a wide range of abilities, including standing on very challenging surfaces and squatting.
There are millions of people who face the loss of their eyesight from degenerative eye diseases. The genetic disorder retinitis pigmentosa alone affects 1 in 4,000 people worldwide.
Combining tissue engineering and regenerative medicine, scientists have fabricated a series of heart valve replacements with the ability to incorporate host cells, enabling them to regenerate and grow over time.
Cutting-edge 3D scanners have been put to the test by researchers from the University of Southampton and partners Exceed Worldwide to help increase the quality and quantity of prosthetics services around the world.
In recent years, hospital charges and Medicare payments for patients with hip fractures have increased much more rapidly than charges and payments for orthopaedic surgeons, reports a study in the Journal of Orthopaedic Trauma.
Robotics researchers are developing exoskeletons and prosthetic legs capable of thinking and moving on their own using sophisticated artificial intelligence (AI) technology.
MIT researchers have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their "phantom limb" is in space.
Hernias are one of the most common soft tissue injuries. Hernias form when intra-abdominal content, such as a loop of the intestine, squeezes through weak, defective or injured areas of the abdominal wall.
European researchers have been building the Virtual Physiological Human (VPH), a full computer model of the body. Through this process, an EU-funded project focused on improving cardiovascular care, and several key results are now being implemented by industry.
Transmitting sensory signals from prostheses to the nervous system helps leg amputees to perceive prosthesis as part of their body.
Advances in neuroscience and engineering have generated great hope for Luke Skywalker-like prosthetics: robotic devices that are almost indistinguishable from a human limb.
The U.S. Food and Drug Administration today approved the Osseoanchored Prostheses for the Rehabilitation of Amputees (OPRA) Implant System, the first implant system marketed in the U.S. for adults who have transfemoral—or above-the-knee—amputations and who have or are anticipated to have rehabilitation problems with, or cannot use, a conventional socket prosthesis.
