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.
02.03.2023In the ImageTox project, the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) and the CISPA Helmholtz Center for Information Security are pooling their expertise in the fields of drug discovery and artificial intelligence (AI).
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.
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.
17.02.2023DNA can help to stimulate bone healing in a localised and targeted manner, for example after a complicated fracture or after severe tissue loss following surgery.
09.02.2023Miniature assistants can act as a stimulus in cases of tinnitus or digestive tract disorders or help a person’s hand to regain the ability to grip.
25.01.2023Fraunhofer researchers have now developed a new method for the production and clinical application of stem-cell-based retinal implants, which could contribute towards the successful treatment of AMD.
20.01.2023Imperial researchers have developed a low-cost, easy-to-manufacture stabiliser for broken bones to help in regions where such devices are expensive or in short supply and people sometimes resort to homemade options.
19.01.2023Osaka Metropolitan University scientists have revealed that knee extension velocity while seated is a stronger predictor of walking performance than muscle strength in elderly patients after their total knee arthroplasty (TKA) surgery.
16.01.2023Older knee replacement designs are just as effective as newer models – according to new research from the Norfolk and Norwich University Hospital and University of East Anglia.
08.06.2022We are nowadays already able to weave implants out of artificial fibers that can replace tissue or heal injuries. Different materials like polymers or nitinol are used to create flexible shapes. But the materials and their uses can still be improved.
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.
03.02.2022The waiting time for a donor organ is long nowadays since the need for organs vastly exceeds their availability. But we have possibilities to improve the situation and help as many people as possible to survive despite organ failure: Some organ functions can already be substituted by technology. But medicine is also researching ways to make more organs available for transplant.
03.01.2022Patients waiting for a donor organ must have a lot of patience and a bit of luck. Aging and a rise in chronic disease prevalence means the need for donor organs is much greater than the number that is available. To help those who need organ transplants, scientists must create new technologies.
03.01.2022Extracorporeal membrane oxygenation (ECMO) is often a last resort treatment for patients with acute respiratory failure. The method uses an external pump to circulate blood through an artificial lung back into the bloodstream. However, the use of ECMO for long-term support is not possible for patients with chronic respiratory failure.
01.12.2021Disease, injury, or a condition you were born with – reasons why some people must live without one or several of their five senses. Fortunately, there are many modern sensory aids that help replace one sense with another, which is especially the case when it comes to vision and hearing. Given technology's advancements, can artificial or biological implants someday soon be a viable alternative?
01.12.2021We can replace certain functions of the body with implants nowadays, others we cannot. When it comes to the human senses, we are still quite at the beginning. The technologies and materials we can use are way to coarse compared to our nervous system. But implants can also help us to maintain senses.
01.12.2021Chronic conditions require close monitoring to ensure a successful therapeutic outcome. Unfortunately, patients aren't always able to perform their own measurements and the exam intervals between appointments are frequently too long. An innovative implant is designed to address this gap in glaucoma care and treatment and enable patients to make intraocular pressure measurements on their own.
01.12.2021Cochlear implants are devices that partially restore hearing in wearers. Unfortunately, the signal transmission from the implant to the auditory nerve is still rather basic, thus limiting the sound quality. Future implants could be more accurate in this setting by using light versus electrical pulses to stimulate nerve cells in the ear.
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.
09.08.2021Stroke rehabilitation exercises are essential to regain mobility and strength in the body. Each patient recovers lost skills and function differently. A recent study has now examined how vagus nerve stimulation with electrical impulses during stroke rehab could improve arm mobility.
15.07.2021Excessive noise, hearing loss, vascular constriction, old age – hearing difficulties can be caused by many factors. To help improve the quality of life of people with hearing impairment, Mannheim start-up Vibrosonic have developed a new, innovative hearing aid with an integrated loudspeaker that sits directly on the eardrum.
02.07.2021A new biocompatible polymer-based composite material could soon replace metal plates in treating difficult and unstable fractures. Developed at KTH Royal Institute of Technology in Stockholm, the newly-developed material is as strong as dental composites yet non-toxic.
07.06.2021Lower leg fractures put a great strain on patients due to their long healing process. In the future, an intelligent implant could control how the bone grows together again and thus optimize the healing process. In our video, you can learn from the developers at Saarland University how this works and what role artificial intelligence plays here.
25.05.2021Diseases can affect the lungs in different ways that can be challenging. If the lungs are badly damaged and artificial ventilation (also called artificial respiration) is no longer effective, an ECMO machine comes into play. Right now, artificial lungs reside outside the body and cannot be implanted.
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.
01.02.2021Drugs always have undesired side effects. Cytostatics are powerful drugs used to treat cancer. They reach almost all cells in the body, killing healthy cells as well as cancer cells in the process. A targeted delivery to the specific cellular site would be a gentler treatment.
01.02.2021Therapies need to be carried out with high reliability by trained personal. This will not change in the future. But maybe we will be able to let systems in the patient’s body do some of the work. Some approaches are already aiming to make implants more independent so they will be able to flexibly react to changes. Read more in our Topic of the Month!
01.02.2021In theory, autonomous medical technologies can be used in a diagnostic or therapeutic capacity inside the body under certain conditions. This may not sound like a new invention at first. After all, implantable cardioverter-defibrillators have monitored and fixed abnormal heart rhythm for many years.
01.02.2021Today we use implants to stabilize or compensate for injuries inside the body and to aid in the healing process. Implants cannot act autonomously and treat the patient if they deem it necessary. However, it is just a matter of time before this happens because research on intelligent implant materials that respond to stimuli is on the cusp of a breakthrough.
23.11.2020Active implants such as pacemakers revolutionized healthcare decades ago. But they also have disadvantages: their size and relatively short life span, for example. At Fraunhofer IZM, research is therefore being conducted on durable microimplants that stimulate nerve cells electrically in a targeted manner and are even to be used to treat multiple sclerosis.
03.02.2020Regenerative 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.
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.
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.
01.01.2020Joints 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.
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.
27.02.2019Many patients suffering from arthrosis or other kinds of damage in the hip joint need an endoprosthesis at some point. However, this prosthesis can loosen again after some time, so that it must be replaced. In order to delay this replacement surgery for as long as possible, the TH Mittelhessen University of Applied Sciences develops a new diagnostic method.
