AI could expand healing with bioscaffolds

22/09/2020

A dose of artificial intelligence can speed the development of 3D-printed bioscaffolds that help injuries heal, according to researchers at Rice University. A team led by computer scientist Lydia Kavraki of Rice's Brown School of Engineering used a machine learning approach to predict the quality of scaffold materials, given the printing parameters.

Repurposed spinal stimulators to restore touch in lost limb

21/07/2020

Imagine tying your shoes or taking a sip of coffee or cracking an egg but without any feeling in your hand. That's life for users of even the most advanced prosthetic arms. Although it's possible to simulate touch by stimulating the remaining nerves in the stump after an amputation, such a surgery is highly complex and individualized.

Active photonic wireless system to power medical implants

08/07/2020

Over the past few decades, medical technology seen various advances in terms of the scope and efficiency of implant devices. Developments in medical research have led to the emergence of electronic implants, such as pacemakers to regulate the heart rate and cerebral spinal shunts to control the flow of spinal fluid. Most of these medical devices require a constant source of energy to operate.

Special coatings to reduce complications after implant surgery

01/07/2020

New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the International Journal of Molecular Sciences.

New heart valve could transform open heart surgery

30/06/2020

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team’s latest in-vitro results suggest that the PoliValve could last for up to 25 years.

Regenerative medicine: creating a new body?

03/02/2020

Regenerative medicine aims to repair the human body after injuries, accidents or major cancer surgery. Unfortunately, we are still not at a stage where this process can achieve optimal results for every conceivable situation. Having said that, various new methods are on the cusp of breakthrough.

Endoprotheses: between possibility and reality

01/01/2020

When natural joints lose their ability to function, they can be completely or partially replaced by artificial joints, also called endoprotheses. Endoprotheses must be of a certain quality, as they should remain in the body as long as possible. In addition to some risks, endoprotheses can also contribute to a mobile and carefree life for young and old.

APRICOT-project: implant "help(s) patients heal themselves"

01/01/2020

Today, people tend to live longer, while an increasing number of patients suffer from osteoarthritis. Even younger generations are now at a higher risk of getting osteoarthritis due to the frequent use of mobile devices. The EU research project APRICOT aims to develop a novel type of implant for the treatment of osteoarthritis of the hands – helping patients heal themselves.

Endoprotheses: regaining independence and mobility

01/01/2020

Joints can suddenly or gradually deteriorate and lose their natural strength, whether it’s due to accidents, diseases or simple wear and tear. In some of these cases, implants of artificial joints – endoprostheses - can help. As a joint replacement, they are designed to stay in the body for as long as needed and as such improve the patient’s quality of life and mobility.

Orthopedic implant: More comfortable thanks to full weight-bearing capacity

08/03/2019

Orthopedic implants – they are a necessity when it comes to congenital or acquired limb length discrepancies. However, full weight-bearing during the limb lengthening process is not feasible with previous implant models. For the first time, the 3D Surgery division at the Medical Center of the University of Munich has succeeded in using an implant that facilitates immediate weight-bearing.

Regenerative heart valves: from simulation to replacement

23/07/2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Early detection: Tattoo signals cancer – and more

09/07/2018

People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.

Tissue engineering: how to grow a bypass

23/04/2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.

Surgical navigation systems – with precision to the destination

06/03/2018

With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
