Iliac crest reconstruction: 15 patients recruited into GreenBRIC study

GreenBone Ortho, a company specialising in bone regeneration, announces that it has achieved its aim of recruiting 15 patients into the GreenBRIC study. GreenBRIC study is a prospective, open label, single-arm, First-in-Human clinical investigation, in male and female patients, aged between 18 and 70 years, undergoing surgery to correct bone defects using GreenBone Implant, specifically for iliac…

Self-powered implant

New device to speed up bone healing

Researchers know that electricity can help speed up bone healing, but “zapping” fractures has never really caught on, since it requires surgically implanting and removing electrodes powered by an external source. Now, researchers at the University of Wisconsin–Madison have expanded on this principle and developed a device to speed up bone healing.

Study on devices and implants

AI could improve speech recognition in hearing aids

In noisy environments, it is difficult for hearing aid or hearing implant users to understand their conversational partner because current audio processors still have difficulty focusing on specific sound sources. In a feasibility study, researchers from the Hearing Research Laboratory at the University of Bern and the Inselspital are now suggesting that artificial intelligence (AI) could solve…

Transient implant

A pacemaker that dissolves when it's no longer needed

Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it’s no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components…

New imaging technique to improve 3D printed bio-implants

University of Birmingham scientists have developed a new microscopic imaging approach to take a closer look at 3D-printing for developing future patient implants, as well as improved disease modelling and drug screening. Additive manufacturing (3D printing) platforms create bioprinted structures by moving a special bioink, containing cells, biomolecules and materials, through a narrow tube, but…

Harmony Transcatheter Pulmonary Valve (TPV) System

FDA approval for implant to treat congenital heart disease

The U.S. Food and Drug Administration approved the first in the world non-surgical heart valve to treat pediatric and adult patients with a native or surgically-repaired right ventricular outflow tract (RVOT). The device, called the Harmony Transcatheter Pulmonary Valve (TPV) System, is intended to improve blood flow to the lungs in patients with severe pulmonary valve regurgitation without…

Conductive hydrogel could replace brain tissue

Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals…

New circulation implant to bridge the waiting time for donor heart

With the first-in-man implantation of the Berlin Heart Venous Cannula at the LMU University Hospital Munich, Germany, Berlin Heart offers patients with a failing Fontan circulation a unique chance to survive the waiting time for a donor heart. These patients are in a life-threatening condition: their health has deteriorated so much that they desperately need a new heart, but because of their poor…

Longer lasting implants for younger people

Engineering more durable artificial joints

A £4 million research project will develop a new generation of artificial joints that last longer, produce fewer side effects and are better suited for younger people. The international collaboration, led by the University of Leeds and funded by the EU’s Horizon 2020 programme, will focus on improved design and testing to reduce the chance that the implants develop faults and fail, or cause…

Restoring proprioception after amputation

New surgery improves 'phantom limb' sensation, prosthesis control

Researchers at the Massachusetts Institute of Technology (MIT) have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their “phantom limb” is in space. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as a reduction of limb pain, the researchers say. In most…

Promising alternative to heart transplants

'Artificial aorta' to reduce blood pressure

Engineers at EPFL’s Center for Artificial Muscles have developed a silicone aorta that can reduce how hard patients’ hearts have to pump. Their breakthrough could offer a promising alternative to heart transplants. “Over 23 million people around the world suffer from heart failure. The disease is usually treated with a transplant, but because donated hearts are hard to come by, there is an…

Brain implants: the key to mobility after stroke?

Someone has a stroke every 40 seconds in the US, resulting in death every 4 minutes. Stroke is the leading cause of disability from a medical condition. When it happens, blood clots or bleeds kill a part of the brain – it goes dark – and can no longer control part of the body. People stop being able to walk, see, talk, or control their hand or arm the way they once did. Although treatments…

One step closer to regenerative heart valves and stents

Non-degradable prostheses for cardiovascular tissues can be used to replace heart valves and blood vessels, but they can’t stay in the body permanently. In two recent papers, researchers at the Eindhoven University of Technology (TU/e) in collaboration with a number of clinical partners, the Dutch Heart Foundation, and TU/e spin-off companies Suprapolix, Xeltis, and STENTiT have shown how…
