18.10.2019The ability of cataract surgery to restore sight is well known. People say they're stunned by the vibrancy of color after surgery and the improvement in night vision. Some can even reduce their reliance on glasses. But is it possible to quantify that improved quality of vision?
03.10.2019A new way of 3D printing soft materials such as gels and collagens offers a major step forward in the manufacture of artificial medical implants. Developed by researchers at the University of Birmingham, the technique could be used to print soft biomaterials that could be used to repair defects in the body.
25.09.2019The Fraunhofer FEP has developed a process, called SULEEI, which makes it possible to sterilize and preserve decellularized pericardial tissue by means of photo-initiated ultraviolet crosslinking with low-energy electron irradiation.
20.09.2019Patients with the rare Loeys-Dietz syndrome suffer from aortic enlargement which may result in sudden over-expansion and a fatal aortic tear. In order to prevent this from happening, an aortic prosthesis must be implanted.
11.09.2019Medical implants of the future may feature reconfigurable electronic platforms that can morph in shape and size dynamically as bodies change or transform to relocate from one area to monitor another within our bodies.
06.09.2019Cardiovascular stents are special implants used to widen blood vessels that have become constricted as a result of calcium deposits. In some cases, the body's immune system can reject these implants in a process known as foreign-body reaction. In a joint project with partners, Fraunhofer researchers have now developed enhanced coatings that substantially improve the biocompatibility of stents.
12.08.2019Approximately one in every thousand children develops a urethral stricture, sometimes even when they are still a foetus in the womb.
09.08.2019Researchers in EPFL's Microsystems Laboratory are now working on a biodegradable implant that would release a local anesthetic on-demand over several days. Not only would this implant reduce patients' post-op discomfort, but there would be no need for further surgery to remove it.
07.08.2019Like real bone, the material developed at Oregon Health & Science University has a 3D mineral structure populated with living cells, providing a unique model to study bone function, diseases, regeneration.
06.08.2019Using genetic tools in mice, researchers at Johns Hopkins Medicine say they have identified a pair of proteins that precisely control when sound-detecting cells, known as hair cells, are born in the mammalian inner ear. The proteins, described in a report published June 12 in eLife, may hold a key to future therapies to restore hearing in people with irreversible deafness.
05.08.2019A team of researchers from Carnegie Mellon University has published a paper in Science that details a new technique allowing anyone to 3D bioprint tissue scaffolds out of collagen, the major structural protein in the human body. This first-of-its-kind method brings the field of tissue engineering one step closer to being able to 3D print a full-sized, adult human heart.
26.07.2019McMaster researchers have developed a novel new gel made entirely from bacteria-killing viruses.
25.07.2019The National University of Science and Technology MISIS together with their colleagues from the N.N. Blokhin National Medical Research Centre of oncology developed a unique implant to replace the damaged bone fragment. The implant, which imitates real bone structure, was installed to a domestic cat with osteosarcoma by surgeons of the veterinary clinic "Biocontrol".
24.07.2019Dr. Wim Melis from the University of Greenwich is working on deconstructing and reconstructing audio signals with extremely high accuracy.
08.03.2019Orthopedic 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.
23.07.2018Every 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.
09.07.2018People 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.
23.04.2018A 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.
06.03.2018With 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.
16.11.2017The quality of the implants and orthopaedic instruments used is a fundamental prerequisite for the success of surgical procedures. They have to meet very high international standards. Find out more about the orthopaedic implants and tools of the Indian company GPC Medical Ltd. in our interview.
22.05.2017For many years, cochlear implants have restored a sense of hearing in people with certain types of hearing loss. For surgeons, the implantation requires a precise attention to detail under the microscope. The results for the patients improve significantly with a more precise placement of the electrode array. The use of a surgical robot can increase the accuracy of the procedure.
10.04.2017People with hip osteoarthritis often suffer from severe pain and only an endoprosthesis implantation can provide relief. This involves a major intervention and long-term rehabilitation because the implant requires the removal of a section of the thigh bone. The "MioHIP" research project looks for an elastic alternative.
01.02.2017Ophthalmology procedures and eye surgeries have been around since ancient times. Today we can hardly imagine the types of circumstances that surrounded any surgical procedures to our perhaps most important sense organ in those days and later eras. Meanwhile, the present and future of this medical specialty looks all the more promising.
