Implants & Prosthetics

Implants used to monitor bodily functions or to provide drugs would advance personalized medicine, but there is an inherent problem—the human immune system recognizes the device as an invader and encapsulates it, preventing the device from working properly. To combat this problem, researchers at the...

In a first-of-its-kind operation in the US, a team of doctors at Duke University Hospital, Durham, NC, helped create a bioengineered blood vessel and transplanted it into the arm of a patient with end-stage kidney disease. The procedure was the first US clinical trial to test the safety and...

Researchers at The Ohio State University, Columbus, say that their technology is closing in on creating low-cost electronic devices that work in contact with inside the body, and that their first planned use of the technology is a sensor that will detect the very early stages of organ transplant...

Combined with state-of-the-art micro-sculpting techniques, a new resin holds promise for making customized electrodes for fuel cells or batteries, as well as biosensor interfaces for medical uses. A rabbit sculpture, the size of a typical bacterium, was one of several shapes created by a team of Japanese...

The American Orthotic & Prosthetic Association (AOPA) launched its “Coalition to Walk and Run Again,” an effort to aid uninsured and underinsured victims of the April 15th Boston Marathon terror attack. The bombing killed 3 people and left more than 200 injured,...

According to a new study conducted in controlled laboratory conditions, sensors that pick up the rhythm of a beating heart in implanted cardiac defibrillators and pacemakers are vulnerable to hacking. In experiments using simulated human models, an international team of researchers demonstrated that...

Ever since he was six weeks old, an Ohio infant with a condition called tracheobronchomalacia would stop breathing because part of his windpipe carrying air to his left lung would collapse, requiring emergency assistance. But, thanks to a team of doctors and engineers at the University of Michigan,...

Scientists at the University of Washington, Seattle, have created a synthetic substance that can fully resist the body’s natural attack response to foreign objects. They say that devices such as artificial heart valves, prostheses and breast implants could be coated with this polymer to prevent the body...

Once implanted, coronary artery stents to prop open blood vessels usually remain in place for the rest of the patient’s life. The longer a stent is in place, the greater the risk of late-stage side effects. That's why researchers are trying to develop a bioabsorbable stent, one that will gradually and...

The American Orthotic & Prosthetic Association (AOPA) launched its "Coalition to Walk and Run Again," an effort to aid uninsured and under-insured victims of the April 15th Boston Marathon terror attack. The bombing killed 3 people and left more than 200 injured, several of...

Scientists at Carnegie Mellon University, Pittsburgh, PA, are developing edible electronic devices that can be implanted in the body, and say that the device could be programmed and deployed in the gastrointestinal tract or the small intestine and once the battery packaging is in place,...

Researchers say that a new type of soft material they have created by using a unique 3D printer connects thousands of water droplets, 50 microns in diameter each, encapsulated within lipid (fat) films, which can perform some of the functions of the cells inside our bodies. These printed “droplet networks,” they say...

Many medical implants use hard materials that connect to or pass through soft body tissue. This mechanical mismatch can lead to problems like skin breakdown at abdominal feeding tubes in stroke patients and where wires pass through the chest to power assistive heart pumps. So researchers at Case Western Reserve...

Around 17 million people in Germany suffer from impaired hearing. A new device being developed at the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), Stuttgart, Germany, can, researchers say, improve patients’ hearing and can be implanted during outpatient surgery. Hearing...

Researchers at the University of Pittsburgh, with the support of a $3.4 million National Institutes of Health grant, are working to develop an artificial lung to serve as a bridge to transplant or recovery in patients with acute and chronic lung failure. The project aims to develop a compact respiratory...

A team of scientists at the École Polytechnique Fédérale de Lausanne (EPFL), one of the two Swiss Federal Institutes of Technology, have developed a tiny implantable device that can analyze the concentration of up to five proteins and organic acids in the blood simultaneously, and then transmit the...

Longtime cochlear implant users are reporting dramatic improvements in their hearing, thanks to new image-guided programming methods developed by researchers at Vanderbilt University, Nashville, TN. Using a patent-pending nonsurgical process, audiologists can fine-tune and customize cochlear implant programming,...

A team of neuroengineers based at Brown University, Providence, RI, has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described...

Researchers at the North Carolina State University, Raleigh, have successfully coated polymer implants with a bioactive film that, they say should improve the success rate of the implants, typically used in spinal surgeries. The polymer contained in these implants, called Polyetheretherketone...

A team of bioengineers and physicians at Cornell University, Ithaca, NY, have created an artificial external ear, using 3D printing and injectable molds, that looks and acts like a natural ear. This could give new hope to children born with a congenital ear deformity, or to those who have lost all or...

Researchers at Northwestern University, Evanston, IL and the University of Illinois have demonstrated a stretchable lithium-ion battery can power their innovative stretchable electronics. The stretchable electronic devices now could be used anywhere, including inside the human body, they say,...

The Florida State University, Tallahassee, and its High-Performance Materials Institute are leading a major partnership to develop the next generation of prosthetic limbs for military-veteran amputee patients, thanks to a new contract with the U.S. Department of Veterans Affairs. The two-year,...

University of California-Irvine neuroscientists have developed a unique method to stop severe episodes of epileptic seizures with fiber optic light signals. Using a mouse model of temporal lobe epilepsy, the research team created an EEG-based computer system that activates hair-thin optical strands implanted in...
