ORNL, Southern Cal set sights on preventing blindness

... proportions," said Greenbaum, lead author of a paper published in IEEE Transactions on Biomedical Engineering. Animal studies for the metabolic prosthesis technique are under way. The procedure involves surgically implanting a feedback-controlled three-electrode electrolysis system that stimulates ...

Sports technology for para-athletes: Closing the gap

... , authored by Lechler and Lilja describes the clinical view of fitting an amputee with a prosthetic leg. The paper provides a general overview on prosthesis technology. It highlights the challenges and disadvantages of a prosthetic fitting including the difficulties in selection, fitting and the ...

Innovative surgery by MSU veterinarian provides new lease on life to dogs

... 11-year-old yellow Labrador retriever, was the first dog in the Midwest and only the 11th in the world to undergo surgery for a new, cementless elbow prosthesis last April. The procedure, done at MSU's Veterinary Teaching Hospital by veterinary orthopedic surgeon Loic Dejardin, has left Jake pain free from ...

NJIT biomedical engineer receives NSF Career Development Award

... injuries to the spinal cord and other nerve tissue. The team also hopes to develop a nerve-tissue interface that would allow for a thought-controlled prosthesis that would behave like a natural limb. The research recapitulates an unrecognized and extremely rapid form of nervous system growth that occurs ...

Thinking makes it so: Science extends reach of prosthetic arms

... to close your hand or bend your wrist, said Kuiken. Quite frankly, most people with a unilateral shoulder disarticulation amputation dont wear a prosthesis at all: Its just too cumbersome. More moves While TMR is more intuitive and natural, Kuiken and his team wanted to see if they could extract ...

MIT aids creation of neural prosthetic devices

... to treating paralysis and amputation. Here, electronics are used to monitor the neural signals that reflect an individual's intentions for the prosthesis or computer they are trying to use. Algorithms form the link between neural signals that are recorded, and the user's intentions that are decoded to ...

Herr receives Heinz Award for Technology, the Economy and Employment

... and other technologies. Most recently, Dr. Herr and his Biomechatronics research group at the MIT Media Lab have developed a robotic foot-ankle prosthesis capable of propelling the wearer forward and varying its stiffness over irregular terrain, successfully mimicking the action of a biological angle, ...

Paracetamol, one of most used analgesics, could slow down bone growth

... the researcher should be cautiously taken, specially in situations which require a rapid bone tissue regeneration, such as after placement of a prosthesis or dental implant. Other anti-inflammatories which have no effects on bone growth should be used instead. Results of her work can not be confirmed in ...

Six previously blind patients detect light, motion, identify objects with retinal prostheses

... six patients-who had been implanted with a single prosthesis in their "worse eye" for between 5 and 33 ... images. Second Sight's intraocular retinal prosthesis is taking the first step to replacing those cells ... E. de Juan, Jr., "Implanted Intraocular Retinal prosthesis in Six Blind Subjects," ARVO 2005, ...

Biotechnology's newest chemical tool

... more Degrees of Freedom than Degrees of Movement (motors); it means the prosthesis has a self-adaptive grasp. "This is a fundamental feature of the CYBERHAND prosthesis because only a limited number of control signals are available for user's ...

Conceptualizing a cyborg

... idea is to use regions of undamaged nervous tissue to provide command signals to drive a device, such as an artificial limb. The challenge is for a prosthesis to perform naturally, relaying two-way communication with the patient's brain. For example, the patient's thoughts could convert nerve signals into ...

Artifical cornea lets woman blind 20 years see

... plate with the donor cornea tissue sandwiched in between. The surgeon then removes most of the damaged cornea from the patient's eye so that the new prosthesis can be sewn into place using sutures to connect the donor tissue and keratoprosthesis to the patient's remaining corneal tissue. "Getting an ...

Researchers discover way to make cells in the eye sensitive to light

... in the eye responsive to light is not a cure for blindness, the team are collaborating with engineers from Imperial to develop a functional retinal prosthesis which would allow the information from the light responsive cells to be used by the brain to process ...
