16/01/2019For the first time, researchers at University of California San Diego School of Medicine and Institute of Engineering in Medicine have used rapid 3D printing technologies to create a spinal cord, then successfully implanted that scaffolding, loaded with neural stem cells, into sites of severe spinal cord injury in rats.
11/01/2019With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.
04/01/2019A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson's.
10/12/2018A team of surgeons from the Perelman School of Medicine at the University of Pennsylvania are the first in the world to use a surgical robot to assist with a bilateral free flap breast reconstruction - a procedure in which tissue is taken from the lower abdomen and used to rebuild the breast. The robot allows surgeons to make a much smaller incision into the abdominal wall muscles.
07/11/2018Soon you may no longer have to worry about how long your dental repairs will last. A new dental reconstruction material developed in Sweden offers unprecedented improvements over existing acrylate-based fillers.
06/11/2018As part of the Marie Skłodowska Curie Action (MSCA), which has just been launched, 15 young researchers investigate biodegradable magnesium implants. The project is coordinated by the Helmholtz Zentrum Geesthacht (HZG); it brings together eight universities and research institutions as well as four technology companies from eight European countries.
24/10/2018Researchers at McMaster University have solved a vexing problem by engineering surface coatings that can repel everything, such as bacteria, viruses and living cells, but can be modified to permit beneficial exceptions.
24/10/2018Neuroprosthetics - implants containing multi-contact electrodes that can substitute certain nerve functionalities - have the potential to work wonders. They may be able to restore amputees' sense of touch, help the paralyzed walk again by stimulating their spinal cords and silence the nerve activity of people suffering from chronic pain.
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.
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.
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.
