17/06/2021Stereotactic systems are special devices used in neurosurgical procedures. Until now, conventional production methods have meant that these devices are not only expensive to manufacture, but are also geometrically limited.
17/06/2021Millions of people with diabetes are at risk of developing foot ulcers, which often lead to amputations and other health complications. Now, Scientists from the Centre for Biomechanics and Rehabilitation Technologies (CRBT) have developed a new method to reliably detect this risk without the need for complex electronic in-shoe sensors.
27/05/2021Researchers have flipped traditional 3D printing to create some of the most intricate biomedical structures yet, advancing the development of new technologies for regrowing bones and tissue.
07/05/2021Professor Arda Gozen looks to a future someday in which doctors can hit a button to print out a scaffold on their 3-D printers and create custom-made replacement skin, cartilage, or other tissue for their patients.
05/05/2021A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.
26/04/2021The Technology Transfer Center for 3D Printing in Medical Technology – Swiss m4m Center, in short – meets the requirements of ISO standard 13485:2016; it is thus allowed to produce implants and instruments for human patients. The starting signal for promising projects with Swiss SMEs: The partner network already comprises 45 companies and research institutions.
20/04/2021The idea is as appealing as it is obvious: After a diagnosis of painful hip osteoarthritis, medical imaging creates a high-resolution 3D image of the defunct hip joint – and thus the basis for a customized implant. The data is processed further and ultimately ends up as a digital blueprint in a 3D printer, which produces the individual piece with a precise fit and at optimized cost.
13/04/2021New insights into the three-dimensional (3D) morphology of the human uterine endometrium could advance our understanding of the mechanisms of endometrial regeneration and fertilized egg implantation while clarifying the pathogenesis of menstrual disorders, infertility and endometrium-related diseases such as adenomyosis, endometriosis, endometrial hyperplasia and endometrial cancer.
22/03/2021The Research Group on Synthetic Biology for Biomedical Applications at Pompeu Fabra University in Barcelona, Spain, has designed a cellular device capable of computing by printing cells on paper. For the first time, they have developed a living device that could be used outside the laboratory without a specialist, and it could be produced on an industrial scale at low cost.
01/12/2020The big hope of bioprinting is to someday be able to print whole human organs. So far, the process has been limited to testing platforms such as organs-on-a-chip. That's because the actual printing process already poses challenges. Scientists need suitable printing materials that ensure the cell's survival as it undergoes the procedure. The Fraunhofer IGB is researching and analyzing this aspect.
01.12.2020It aims at the production of test systems for drug research and gives patients on the waiting lists for donor organs hope: bioprinting. Thereby biologically functional tissues are printed. But how does that actually work? What are the different bioprinting methods? And can entire organs be printed with it? These and other questions are examined in our Topic of the Month.
01/12/2020How do cells react to certain drugs? And how exactly is new tissue created? This can be analyzed by using bioprinting to embed cells in fine frameworks. However, current methods are often imprecise or too slow to process cells before they are damaged. At the TU Vienna, a high-resolution bioprinting process has now been developed using a new bio-ink.
01/12/2020Implants, prostheses and various other components made of plastic, metal or ceramics are already being produced by additive manufacturing. But skin, blood vessels or entire organs from the printer – is that possible? For years now, intensive research has been underway into the production of biologically functional tissue using printing processes. Some things are already possible with bioprinting.
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.
03/02/2020Collagen is the stuff that holds our bodies together and that houses our cells. In regenerative medicine, it is also the stuff that can be applied to wounds to support healing. However, collagen from animal or human sources has some drawbacks for today’s medicine. This is where rhCollagen from the Israeli company CollPlant comes into play.
03/02/2020Severe wounds heal slowly and leave scars. This is why we have been using regenerative therapies for some time now to accelerate and improve healing. They also help to avoid permanent damage. Still, complex applications like replacing organs or limbs will rather remain vision than become reality for a long time.
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.
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.
