10.03.2023Patients with complex coronary artery disease who underwent a stenting procedure guided by intravascular imaging were nearly 40% less likely to die of heart disease, have a heart attack caused by a new blockage in the treated artery or need a repeat stenting procedure in the treated artery, compared with similar patients.
08.03.2023In patients with heart failure and a poorly functioning heart valve, a minimally invasive procedure using a clip to repair the valve was safe, cut the rate of hospitalizations for heart failure by 47% and reduced deaths from any cause by almost 30% after five years of follow-up.
07.03.2023Good design not only pleases the eye or the hand. It also guarantees intuitive and safe use and a long service life. Especially in medical technology, this can make a big difference – for staff as well as patients. Medical designers are therefore in great demand. At MEDICA 2022, we talked to two of them about their profession.
27.02.2023The ear, nose and throat are full of tiny structures, and each plays an important role in the health of a person. The inside of the ears makes it possible for us to hear, while the inside of our nose enables us to smell. The larynx contains the vocal cords, which allow us to speak and stay connected to the outside world.
27.02.2023Until now, robots have assisted surgeons in the operating room to enhance their capabilities. CASCINATION is a Swiss medical device company who has teamed up with MED-EL – the Innsbruck-based hearing implant company – to develop a system that can perform an autonomous cochlear implantation. Since then, HEARO has been successfully used – including at the Medical University of Vienna (MedUniWien).
27.02.2023The paralysis of the vocal folds, the vocal fold paresis (also known as vocal cord paralysis) is a condition in which most patients cannot control the movement of the muscles that control the voice. This can make it hard to speak, prompting a reduction in speech volume that makes it challenging to understand the person. Some patients may even have difficulty breathing.
27.02.2023Speaking and hearing are the two most important abilities that connect humans to their environment. If they get limited through disease or injury, it is all the more important to restore them as broadly as possible. Depending on the cause for their limitation, there are different surgical treatment possibilities. We take a look at current methods in our Topic of the Month.

01.03.2022Catheter ablation is a way to treat irregular heartbeats, or arrhythmias, like atrial fibrillation. Although catheters are classified as single-use or disposable devices, the complex instruments can be reused multiple times thanks to extensive reprocessing.
01.03.2022People who suffer from partial or total loss of vision caused by illness must use assistive technology to replace their sense of sight. In recent years, implants offered hope of restoring limited functional vision. Now an innovative microchip designed to help with age-related macular degeneration (AMD) is currently undergoing international testing.
16.11.2021The smaller the surgery, the more precise it has to be. That's why surgeons need high-precision technology for minimally invasive procedures. Robots are often already used in the OR to perform surgery with millimeter precision. At MEDICA 2021, we learn more about the status quo of technology that enables minimally invasive procedures.
15.09.2021Precise, extremely quick and accurate – a new kind of navigation device in the OR uses a highly-developed camera technology to guide the surgeon through difficult procedures – directly in the OR. Prof. Ulf Liljenqvist, Chief Medical Director of the Clinic for Spinal Surgery at the St. Franziskus Hospital Münster, talks about his experiences in using the device.
08.09.2021Focused ultrasound waves create microbubbles in a fluid – a phenomenon called cavitation. In a current study, this process is used to destroy liver tumors and metastases.
23.08.2021We cannot heal Parkinson’s disease yet, all we can do is alleviate the symptoms. One possibility to do this are implantable electrodes that stimulate part of the brain and counteract the characteristic tremor. In our video, Prof. Cordula Matthies and Prof. Jens Volkmann from the University Hospital Würzburg explain how this stimulation can be targeted better with a new electrode generation.
02.08.2021Surgical intervention is often inevitable when blood vessels become narrowed, blocked, or damaged. Surgeons use stents and medical balloons to open and widen the arteries, suck out the obstructing clots and use a catheter to examine the vessels. Intraoperative cardiovascular imaging is an essential tool to guide the catheters and instruments during the minimally invasive procedures.
02.08.2021A high degree of precision is required for operations involving the cardiovascular system. This is based on medical imaging. In practice, however, these still face a number of challenges that can impair image quality. The further development of imaging techniques represents a forward-looking field of research in order to be able to improve surgical treatment.
06.07.2021The most important resource in surgical education is the hands-on experience young surgeons are able to get in the OR. But the possibilities to perform surgery on real patients are very limited, and these situations cause insecurity and stress in beginners.
28.06.2021In December 2017, Purenum GmbH started its business as a spin-off of Fraunhofer IFAM. Its mission is to develop biomimetic adhesives for use in medical technology.
01.04.2021The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.
01.04.2021Surgeons have only limited options to practice surgical techniques before they enter the operating room. The implantation of an endoprosthesis requires extensive practical training since it necessitates strength and utmost precision. The "Dynamic HIPS" project develops a virtual reality hip implant simulator that provides realistic haptic feedback.
01.04.2021Surgeons do not only have to gather theoretical knowledge and practice to perform successful interventions. They also need a good visual thinking and have to know the anatomical characteristics of each individual patient. Some of these tasks will become easier when Virtual and Mixed Reality bring three-dimensional, digital models into their profession.
01.04.2021For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.
15.03.2021Heart surgery is difficult even for experienced surgeons and therapeutical success is not always certain. Physicians need to rely on their experience when choosing and planning the correct intervention. A computer model could help them in the future: The digital twin heart could be fed with patient data and then simulate whether an intervention will be successful.
09.03.2021Robotics has been gaining importance in many areas of life for years, not least in medicine. Robots are already being used in the operating room today, but they do not always play the leading role – a circumstance that will certainly change in the long term.
13.01.2021Aneurysm operations in the brain rank among the most delicate procedures in neurosurgery. The highest demands are placed on surgeons when choosing the type of intervention, planning the route and carrying out extremely delicate procedures on the blood vessel.
23.11.2020Surgeons do not only need much concentration, but also strength and endurance. Robotic arms under their control can do part of this work. Prof. (Saitama Med. Univ.) Dietmar Stephan from the St. Marien Hospital Siegen describes in our video, how controls and haptic feedback can make surgery with a robot easier.
22.09.2020Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.
04.05.2020In the operating room, minimally invasive procedures are increasingly used. Robot-assisted systems are a great help for the surgeon. They support the surgeon and are extremely precise. Through innovative research approaches, robotic systems are constantly evolving.
04.05.2020Surgical robots are transforming the operating room. They deliver many benefits but also present new challenges. That is why the efficient handling of robotic mechanisms must also be reflected in the respective training courses.
04.05.2020More compact, more flexibility, and more precision - these are the main characteristics developers strive for as they advance robotic-assisted surgical systems for the operating room. Several technology providers have already shown how it’s done, including the makers of the popular daVinci Surgical System. Yet for robotic-assisted systems, the sky is the limit.
04.05.2020Robotic surgical systems are often used to perform minimally invasive procedures. The daVinci surgical system is still one of the market leaders and is especially well suited to perform prostatectomies, a surgical option for prostate cancer.
09.03.2020Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.
10.02.2020If life has given you many blessings, you should share them with others – and you also need to be a little crazy. That's Dagmar Braun's point of view. She initiated the construction of a hospital in Togo, Africa. The country currently lacks the system required to deliver comprehensive medical care. Surgical equipment and gynecology devices are much-needed to compensate for these deficits.
03.02.2020Regenerative medicine aims to replace damage in the body with functional tissue and restore normal function. The first defense for large defects are implants made of hydrogels, designed to promote cell growth. They need their own blood supply, which is a problem when it comes to larger implants because you cannot regulate where and how the blood vessels grow - until now.
01.01.2020Joints 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.
01.01.2020Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.
01.01.2020Today, 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.
01.01.2020When natural joints lose their ability to function, they can be completely or partially replaced by artificial joints, also called endoprostheses. Endoprostheses must be of a certain quality, as they should remain in the body as long as possible. In addition to some risks, endoprostheses can also contribute to a mobile and carefree life for young and old.
04.11.2019Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.
22.08.2019The German Medical Award will take place on November 18, 2019, as part of the MEDICA trade fair in Düsseldorf. The ceremony emphasizes the commitment to excellence in cutting-edge care for patients. Doctors, clinical centers and companies in the medical and healthcare industry can demonstrate their achievements in medicine and management in hopes of receiving the coveted award.
08.08.2019After their tumor has been removed, some patients have to return to the hospital to undergo surgery again. That's because the tumor was not precisely identified and was subsequently not completely removed. That's both an ethical and financial dilemma. A new surgery-adjacent procedure is designed to rapidly and accurately detect tumors.
22.07.2019Modern imaging opens news doors to surgeries. Yet it also poses major problems for surgeons: They use two-dimensional images to navigate through a three-dimensional surgical environment, while they continuously have to switch their focus back and forth between the images and the patient. Now help is on the way in the form of interactive 3D projections and mixed reality (MR).
11.06.2019Epilepsy patients are currently treated with either medication or surgical options. The aim is to remove the distinct regions of the brain that cause epileptic seizures. Laser ablation for epilepsy is a new, catheter-based surgical procedure that is now also available in Europe, preventing patients from having to undergo open brain surgery.
01.04.2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
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.
