28/09/2017Different surface topographies and materials provide interesting ways to study cell behaviour and potentially provide novel solutions for treating joint defects. Tissue engineering methods that simulate native cartilage could prove useful to create cartilage implants in the laboratory, according to a doctoral dissertation from Umeå University.
26/09/2017Whether or not we consciously perceive the stimuli projected onto our retina is decided in our brain. A recent study by the University of Bonn shows how some signals dissipate along the processing path to conscious perception. This process begins at rather late stages of signal processing.
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.
10/10/2016The year 2016 brings about the new, eagerly anticipated Medical Device Regulation (MDR). The revision needs to now be implemented by all EU member states in the coming years after there have been ongoing deliberations and negotiations since October 2012.
01/07/2016Technical means that lend superpowers to humans are quite normal in comics and movies. In reality, their purpose is much more mundane: They are supposed to help people with disabilities in everyday life. MEDICA MEDICINE + SPORTS CONFERENCE, that takes place at MEDICA in November, is dealing with this topic, too.
01/05/2016Antibody-coated, drug-eluting stents (AB-DES) feature an exterior coated with immunosuppressant drugs and an interior that is coated with antibodies to accelerate the adhesion of endothelial cells. In theory, this makes it possible to shorten the duration of therapy with blood thinners, which can mean relief for patients from an already difficult situation.
22/04/2016How can you print ceramics, what purpose do they have and how benefits medical technology? Answers provides Dr. Tassilo Moritz from Fraunhofer Institute for Ceramic Technologies and Systems IKTS.
01/02/2016Sometimes, soft tissue in our body needs to be replaced after surgery or an injury. But surgeons are not always able to take tissue from other body parts as a replacement. Then, they need to use implants. The production of soft implants that can constantly endure load and stress like our own tissue is a big challenge for research. Melt electrospinning writing can be a solution.
22/01/2016It may fits, but somewhere it still tweaks. Although a suit off the rack serves its purpose, it is still far from being an ideal solution. With a custom made heart it is different. It is similar with implants. Often patients complain about the fact that those implants feel strange. 3D printing is on the best way to change this. Here, the implants are adapted to the carrier.
08/01/2016There are various artificial heart valves available for children, but they have one essential drawback: they need to be replaced because the children are still growing. The artificial valve, on the other hand, remains the same size – and subsequently becomes too small. This is why an artificial heart valve that grows over time would be ideal.
08/12/2015The closure apparatus between the gallbladder and small intestine is frequently injured during gallbladder surgeries. So far, however, there has been no surgical option to bridge tissue defects. Now, a novel implant made of bacterial nanocellulose (BNC) could change this. Its nanofiber network makes it extremely robust so that it is able to take on a supporting function.
01/07/2015In the case of cardiac arrhythmia, the normal heart rate gets out of balance due to various reasons. In some cases, it is necessary to implant a cardiac pacemaker. Just like with any intervention, this type of surgery also involves risks. In the worst-case scenario, this can lead to abnormal wound healing or obliteration of the vascular system.
22/05/2015Braided stents are nothing new in medicine, but their manufacturing process is still time-consuming. This is why Professor Stefan Jockenhövel from the RWTH Aachen University and his team want to make machine production possible.
08/08/2014A magnesium implant will soon be available to help patients, who exhibit damage in the high-pressure area of the heart. The implant protects a tissue matrix where new cells that replace the affected tissue are meant to grow. The implant itself is supposed to completely dissolve after several months. MEDICA.de spoke with D. Eng. Thomas Hassel about this exciting project.
