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…

Biomimetic scaffold

4D printing could enable vascularization, bone tissue regeneration, spinal fusion

Spinal fusion is frequently performed to restore spinal stability in patients with spinal diseases, such as spinal stenosis, vertebral fractures, progressive deformities, and instability. In the past two decades, there has been marked increase in the number of people over 65 years in age who have needed spinal fusion surgery.

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…

Venous cannula system

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…

1.4 million grant for resorbable implant development

Medtech company BellaSeno and the Fraunhofer Institute for Production Technology IPT have received a grant totaling EUR 1.4 million for the development of commercial-scale, fully automated additive manufacturing of resorbable medical implants. The grant was issued by Germany's Federal Ministry of Education and Research (BMBF) under the funding program KMU-innovativ. BellaSeno and Fraunhofer IPT…

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…

"I See"-Research project

Blindness: Cortical prosthesis provides visual information

Providing the blind with visual impressions: That is the aim of the I See project, in which neuroscientists from the University of Bremen are involved. The approach: A miniature camera collects visual information and translates it into signal patterns that are transferred to brain implants.

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…

Biodegradable implantables

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…

Reforming surgical procedures with 3D printing hubs in hospitals

Increasingly, hospitals use 3D printing in surgery because the technology can enable fast, unique production of patient-tailored tools at relatively low costs. ‘As the technology itself is developing and accelerating at a fast pace, hospitals may be left behind if they choose not to adopt these advances,’ said Limor Haviv, surgical 3D printing designer at 3D4OP. Today, 3D printing is used in…

'Soft' 3D printing could jump-start creation of tiny medical devices

Researchers at the U.S. National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as…
