A new material known as 'fracture putty' could be used to help broken bones heal much more...

Anyone who has ever broken a bone knows that while receiving the injury itself is quite unpleasant, being laid up for several weeks to even a few months afterwards is also no picnic. Help may be on the way, however. The U.S. Department of Defense is funding a study, to develop fast bone-healing treatments that could be used on soldiers, along with civilians and even animals. Already, scientists have gotten promising results in laboratory tests, using something they call “fracture putty.” Read More

An 83-year old woman is the first in the world to receive a full 3D-printed titanium lower...

The ability to create your own replacement curtain rings, door knobs or even a custom chess set at home using a 3D printer like the Replicator or the Cubify 3D printer has the potential to knock global production models on their heads. Such advances are certainly impressive but not quite in the same league as those being made in the field of medicine. We've already seen small bone-like objects printed by Washington State University researchers, and now an 83-year old patient with a serious jaw infection has become the first person to receive a full 3D-printed titanium lower jaw implant. Amazingly, the combined effort by researchers and engineers from Belgium and the Netherlands is said to have allowed the patient unrestricted mandibular movement within a day of surgery. Read More

U.S. researchers have developed a nonsurgical technique to repair severed nerves in minute...

Professor George Bittner and his colleagues at the University of Texas at Austin Center for Neuroscience have developed a simple and inexpensive procedure to quickly repair severed peripheral nerves. The team took advantage of a mechanism similar to that which permits many invertebrates to regenerate and repair nerve damage. The new procedure, based on timely application of common chemicals to the severed nerve ends, could help patients to recover nearly full function in days or weeks. Read More

A clinical trial of the Argus II Retinal Prosthesis involving 30 patients has produced enc...

After receiving European market approval for its Argus II Retinal Prosthesis in 2011, Second Sight has published interim results of an international clinical trial showing encouraging results in blind patients suffering degenerative eye conditions that lead to incurable blindness. Read More

Doctors could soon be diagnosing diseases using breathalyzer-like technology like that use...

Scientists – and dogs – have known for some time that our breath can reveal much more about us than our estimated blood alcohol content. Researchers at the University of Wisconsin-Madison believe that “breathalyzer”-like technology they currently have under development could be used to diagnose a wide range of diseases, such as diabetes, cancer and infections. Such technology, which relies on the fact that many diseases alter the body’s metabolism in distinctive ways, would provide a non-invasive method of detecting disease even before typical symptoms appear.

A new device known as NIRS uses light to non-invasively monitor blood oxygenation in the b...

Approximately one third of stroke patients experience another stroke while they’re still in the hospital. Nurses therefore keep a close eye on them, and arrange for them to be taken for tests if a subsequent stroke is suspected. Unfortunately these tests can be invasive, and in some cases are even potentially harmful to the patient. A new device being developed at the Mayo Clinic in Florida, however, could watch for strokes simply by shining light onto a patient’s forehead. Read More

A prototype pacemaker created by engineers from the University of Michigan could someday d...

A heart-powered pacemaker may sound counter-intuitive, but in essence this is precisely what aerospace engineers from the University of Michigan are proposing. The engineers have come up with a prototype powered by vibrations in the chest cavity - vibrations which are caused mainly by the beating of the heart. Read More

Might Professor Grinstaff's superhydrophobic material one day form the basis of implants t...

Scientists have developed a new material that can slowly release medication over a period of several months. It's hoped that the "superhydrophobic material" may one day lead to implants that would assist in the treatment of chronic pain, and in the prevention of recurring cancer tumors, by gradually releasing medication over a period of months. The team of scientists is now planning in vivo experiments to gauge the effectiveness of the material in living organisms. Read More

RESPeRATE is a device that is designed to lower blood pressure by getting its users to bre...

People suffering from hypertension (also known as high blood pressure) are typically advised to switch to a healthier diet, get more exercise and lose weight, plus they are often put on a combination of several medications. As of today, UK residents are now also able to get a prescription for what is definitely a different type of treatment – a system known as RESPeRATE. It monitors the patient’s breathing and uses sound to guide them into taking longer, slower breaths, thus relaxing their bodies. According to its makers, multiple clinical trials have shown that it causes significant, lasting reductions in blood pressure. Read More

Engineers and researchers at UT Arlington aim to develop a biomask that could revolutioniz...

Engineers and researchers at the University of Texas, Arlington in collaboration with military medical institutions aim to develop a mask that would use mechanical, electrical and biological components to speed up the healing process following severe facial burns. The flexible polymer face mold is to be fitted with sensors for the monitoring of the healing process. If necessary, embedded components would selectively administer the appropriate pharmaceuticals to the right section of the wound. The aim of the Biomask project is not only to prevent further disfigurement, but also to facilitate facial tissue regeneration in injured soldiers. Read More
