Visual cortical prosthesis will bring sight to the blind

Orion Cortical Visual Prosthesis System

American scientists (Baylor College of Medicine, University of California, Los Angeles and Second Sight Medical Products) have created a visual cortical prosthesis to help blind people see. And although this study is in its initial stages, blind patients already recognize points of light on the monitor. The device is called Orion and its principle of operation is quite simple: the visual information is fixed by the camera on the glasses and, bypassing the non-working optical nerves, is transmitted directly to the Orion device, which is implanted in the brain of the patient.

Lyman Connor, General Electric engineer, has created an affordable robotic hand, which demonstrates the functionality of the modern high-end electronic prostheses. He started working on the Bionic Hand Project in his own home three years ago and his goal was to create a complete solution, that would be much more affordable than similar high-end prostheses, which cost about $50,000 – $70,000. Connor has developed the Mano-matic prosthetic device, based on the open-source Robohand project (low-cost prosthetic solutions), that are developing with the assistance of the international engineers’ community.

Exactech, Inc.engineers have developed an innovative total ankle design that combines both anatomic talar and tibial components. It provides the anatomically shaped implants to minimize bone resection while treating patients who suffer from arthritis in the ankle. The Vantage Total Ankle has a surgeon-friendly anatomic design to improve implant’s function and longevity. In the process of developing researchers of Exactech, Inc. has studied many scans of the patient’s ankles to determine the optimum anatomic shape for new implants that could minimize bone resection and to increase fixation of the prostheses.

06:30 AM GMT Groundbreaking amputation method developed

A new way to perform amputations allows doctors to preserve nerves of the limbs, which have been surgically removed. This revolutionary method of limb amputations will significantly improve the use of prosthetics. It was developed by Dr. Matthew Carty with help from the MIT media lab. New amputation procedure allows surgeons to use innovative prosthetic devices that may be attached directly to the nervous system of a user.

In this case, the patient doesn’t use own muscle movements to control prostheses but can control prosthetics more precisely with the brain signals. Read more>>

04:00 AM GMT Hugh Herr describes near future of prostheses

Hugh Herr, a professor at the Massachusetts Institute of Technology (MIT) and founder of BionX Medical Technologies Inc, said at the American Academy of Orthotists and Prosthetists Annual Meeting in New Jersey, that the near future of prostheses will include neural control of innovative bionic limbs and patient’s nerves and muscles. Hugh Herr hopes to give patients a full sense of touch, feel and movement in a year or two. His team of researchers at MIT are developing fast and effective electrical interface between the bionic limbs and the nervous system of humans brain and muscles.

Hugh Herr said:

“We have not yet normalized speed, but that is a key goal. We are now building a 4-degree-of-freedom bionic transfemoral prosthesis. It will have a powered knee, a powered ankle and a powered subtalar joint”.

11:30 AM GMT The world’s first factory to print human organs

Next year in Brisbane, Australia, will be opened The Herston Biofabrication Institute, the world’s first factory for 3D-printing human organs: tissue, bones, cartilage and even organs. This amazing technology will help patients recover much more quickly. Professor Mia Woodruff of the Queensland University of Technology is the head of the project. She plans to employ 60 researchers and to attract $15 million of investment.

Mia Woodruff said:

“The future of healthcare will be more personalized. It will be automated, it will be low cost, low labor and it will be customized to the patient”.

05:20 PM GMT Researchers had made significant progress in developing bionic kidney

Scientists have created a membrane of human cells that can be used as an artificial kidney implant. It filters out bad molecules just like a real kidney doing. Tests showed that the cultured cell layer of the human kidney filtration system functioned as a living membrane.

Devices based on such membrane could someday replace traditional kidney transplants, and patients with kidney failure won’t have to use the bulky dialysis machines to filter their blood. Dr Dimitrios Stamatialis, the lead researcher from the University of Twente, said:

“This study shows the successful development of a living membrane, an important step towards the development of a bio-artificial kidney device”.

01:20 PM GMT 14-year-old Rishabh Java developed bionic arm, which was selected as “Best Innovative Project” on the Gulf 3D Printing Olympiad

14-year-old Rishabh Java, a student from Gems Millennium School, has designed a 3D printed bionic arm and demonstrated its functionality on the Gulf 3D Printing Olympiad, which was organized by the Gems Wellington Academy in Dubai Silicon Oasis by Atlab. Rishabh’s bionic arm was selected as the “Best Innovative Project” of the year. More than 75 teams took part in the competition.

Java developed a low-cost mind-controlled bionic arm that has interface with the nervous system and can be controlled by human’s mind. It uses electroencephalography to read brain’s electrical activity and translates it to simple motions of an arm: shake hands, pick up objects and others. Read more>>
