Innovative Silicone Models Transform Medical Training and Research

Swiss Vascular, an ETH Zurich spin-off, has created highly detailed silicone models of cerebral blood vessels, aiming to enhance medical training while reducing reliance on animal testing. This initiative represents a significant advancement in medical education and research methodologies.

The foundation of this innovation lies in the development of microcapsules intended for targeted drug delivery, particularly in cancer treatment. Researchers faced the challenge of navigating the intricate human vascular system, leading them to explore solutions beyond traditional animal testing. Doctoral students at ETH Zurich utilized 3D-printed vascular models to simulate medical procedures, significantly improving their experimental outcomes.

Under the guidance of esteemed professors at ETH Zurich, the research has evolved into a successful enterprise focused on providing realistic training environments for medical professionals. The silicone models not only minimize animal testing but also enhance the effectiveness of existing research, promoting higher success rates in clinical applications.

Swiss Vascular's models are crafted from advanced synthetic materials that emulate the elasticity and texture of actual human tissue. A notable feature of these models is their transparency, which allows medical practitioners to visualize instrument positioning during procedures. The models are based on detailed MRI and CT scans, accurately replicating blood vessels from both human and animal brains, such as those of pigs and sheep. This precision is critical in time-sensitive scenarios, like stroke treatments, where every moment counts.

The inception of Swiss Vascular was driven by necessity, as the founders received numerous requests from medical researchers and institutions for their innovative models. Officially launched in 2024, the company has since collaborated with various educational and medical institutions, aligning its mission with the principles of the 3R framework--Replace, Reduce, Refine--aimed at promoting ethical research practices.

On June 21, ETH Zurich will host 3R Day, where attendees can explore the practical applications of these models in research and their limitations. Swiss Vascular aims to go beyond model creation by developing a comprehensive simulation platform that allows healthcare providers to practice complex procedures in a risk-free environment.

While challenges related to certification and financial management remain, the commitment of the founders to revolutionizing medical training and research continues to drive their efforts forward.
