Implant

This prototype implant can detect up to five proteins and organic acids at once (Photo: EP...

Blood tests usually involve drawing some blood out of the body. Now scientists from the Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed an implant that allows blood to be analyzed from within the body, with results then transmitted wirelessly to a computer. While still at the experimental stage, the device could make it easier for health care providers to monitor the chronically ill and provide more personalized treatment to cancer patients.  Read More

Dr Rickard Brånemark tests the functionality of the world's first muscle and nerve control...

It took some time, but the age of the cyborg is upon us. For the first time, neuromuscular electrodes that enable a prosthetic arm and hand to be controlled by thought have been permanently implanted into the nerves and muscles of an amputee. The operation was carried out recently by a surgical team led by Dr Rickard Brånemark at Sahlgrenska University Hospital in Goteborg, Sweden.  Read More

Researcher Lawrence Bonassar holds a fabricated ear created with a 3D printer (Photo: Lind...

When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer.  Read More

A implantable material made from a blend of plastics has been developed to regrow damaged ...

Over the past several years, a number of research institutes have been exploring the use of implants made from material with a scaffolding-like structure, as a means of regrowing bone at severe injury sites. Both MIT and Tufts University, for instance, have been working on collagen-based materials. Now, England’s University of Southampton has announced the development of a new type of bone-growing substance, made from plastic.  Read More

This bionic man contains US$1 million worth of artificial limbs, organs, and blood (Photo:...

Are the famous lines "Gentlemen, we can rebuild him – we have the technology" from The Six Million Dollar Man coming true? Perhaps not entirely, but a new Channel 4 documentary entitled How to Build a Bionic Man will demonstrate the current state of the art in artificial limbs, organs, and even blood, through the construction of a 6-foot tall android. The documentary is set to air on British televisions come February 7, but you can learn about what went into it after the break.  Read More

The external sound processor (top) and the actual implant, that make up the Bone Conductio...

There may soon be help for people who have been rendered functionally deaf by problems of the middle ear. Researchers from Sweden’s Chalmers University of Technology have developed an implant that bypasses the defective middle ear, transmitting sounds to the inner ear by sending vibrations right through the skull bone.  Read More

A new approach to surgical weight-loss installs a self-operated stomach pump  (Photo: Shut...

There's good news and bad news in the fight against morbid obesity. The good news is that there is a new approach to surgical weight-loss which is far less invasive than conventional operations. The bad news is how it works.  Read More

Quadriplegic Jan Scheuermann prepares to take a bite out of a chocolate bar she is guiding...

Earlier this year, a 58 year-old woman who had lost the use of her limbs was successfully able to drink a cup of coffee by herself using a robotic arm controlled by her thoughts via a brain computer interface (BCI). Now, in a separate study, another woman with longstanding quadriplegia has been able to feed herself a chocolate bar using a mind-controlled, human-like robot arm offering what researchers claim is a level of agility and control approaching that of a human limb  Read More

Scientists are looking into treating Alzheimer's disease by applying tiny shocks to the br...

The process of deep brain stimulation involves using a pacemaker-like implanted device to apply controlled mild electrical pulses to specific areas of the brain. In recent studies, it has been used – with some success – to treat conditions such as Parkinson's disease, major depression and Tourette syndrome. Now, in the ADvance Study, researchers at several research centers are exploring its use in restoring memory function to people with Alzheimer’s disease.  Read More

MIT engineers have devised a way to stack neurons to form three-dimensional brain tissue (...

A team of researchers from MIT and Harvard Medical School have devised a cheap way of artificially growing three-dimensional brain tissues in the lab. Built layer by layer, the tissues can take on just about any shape and closely mimic the cellular composition of the tissue found in the living brain. The advance could allow scientists to get a closer look at how neurons form connections, predict how cells of individual patients will respond to different drugs, and even lead to the creation of bioengineered implants to replace damaged brain tissue.  Read More
