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.
Infection in penile prosthesis implantation is a significant complication, because the entire device often needs to be removed before the infection can be eradicated.
Urinary incontinence after radical prostatectomy may affect 3-8% of patients and can have a significant negative impact on a patient's quality of life.
In an experiment that could offer a new pathway to restoring vision in people with inherited retinal degeneration, researchers have engineered cells in the eye to be light sensitive that were not before.
Division of the penile suspensory ligament with or without the additional procedures of suprapubic fat pad excision and inverted VY plasty is a simple and commonly used penile lengthening technique. A recent study by C. Y. Li and colleagues from London examined patient satisfaction with penile suspensory ligament division for penile augmentation.
The brain as command center for bodily movement was too simple an idea, thought the Russian physiologist Nicolas Bernstein some 60 years ago.
After a 10-year clinical trial of a jaw joint replacement developed by Peter Quinn of the University of Pennsylvania School of Dental Medicine, the Food and Drug Administration has given it a thumbs-up.
Nine out of ten men fitted with a penile prosthesis were able to have sexual intercourse and eight out of ten were satisfied with the overall results, according to research published in the latest issue of BJU International.
A highly dexterous, bio-inspired artificial hand and sensory system that could provide patients with active feeling, is being developed by a European project.
Altering the standard step-by-step procedure that takes women facing a mastectomy from diagnosis to surgery to reconstruction can improve the process and help in determining if immediate reconstruction is the best course of action, according to new research from the University of North Carolina at Chapel Hill.
Practice makes perfect when people learn behaviors, from baseball pitching to chess playing to public speaking. Biomedical engineers at Washington University in St. Louis have now identified how people use individual experiences to improve performance.
Researchers from Duke University's Medical Center and Pratt School of Engineering have demonstrated that they can grow new human blood vessels from cells taken from patients who especially need such assistance – older adults with cardiovascular disease.
A new Oregon Health & Science University study is opening scientists' eyes to the retina's ability to rewire itself so it can adapt to different levels of ambient light.
Senior engineering students from LeTourneau University are leaving for Kijabe, Kenya, to fit disabled Kenyan children with free prosthetics.
A group of researchers of the Institute of Biophysics (Russian Academy of Sciences), Krasnoyarsk regional clinical hospital and Krasnoyarsk regional department of morbid anatomy under the guidance of .I. Gitelzon, Academician of Russian Academy of Sciences, have tested characteristics of a new polymeric coating for vascular stents.
Researchers from the University of Southern California and the Doheny Eye Institute will be presenting data on the first six patients implanted with an intraocular retinal prosthesis-more popularly referred to as an artificial retina-developed and manufactured in partnership with Second Sight Medical Products, of Sylmar, Calif.
Sales clerks tend to subtly discriminate against overweight shoppers but treat them more favorably if they perceive that the individual is trying to lose weight, according to a study by Rice University researchers.
Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80
A large, multi-center trial of 190 patients shows a new nonsurgical interventional radiology technique can benefit the more than 287,000 kidney failure patients undergoing dialysis in the United States each year.
Pioneering research with combined positron emission tomography (PET) and computed tomography (CT) scans provides accurate detection and localization of foot infection in diabetic patients, according to an article in the March issue of the Journal of Nuclear Medicine.
A number of arthritis sufferers attribute their weight gain to inactivity due to a painful hip or knee. These patients may be disheartened when their post-operative weight either remains the same or increases.
