About

Michael Mattmann is a leading researcher in the field of medical robotics, with a focus on developing advanced, minimally invasive surgical tools. His key research areas include variable stiffness catheters, shape memory polymers, and magnetic guidance systems for targeted drug delivery. Mattmann’s major contributions center on creating submillimeter-scale catheters that can dynamically alter their stiffness, enabling unprecedented compliance control during robotic surgery. His 2021 paper on thermoset shape memory polymer variable stiffness 4D robotic catheters (111 citations) and his work on continuous variable stiffness catheters using phase-change alloys (104 citations) have been highly influential, demonstrating a high stiffness variation critical for safe, adaptive surgical tools. Notably, his 2024 study on magnetically guided microcatheters for injecting magnetic particle swarms (19 citations) addresses a key challenge in deploying microrobots within the human body, overcoming dispersion caused by physiological flows. Mattmann’s hybrid stiffness control strategy, which operates below body temperature to enhance safety, further underscores his innovative approach. With over 250 total citations, his work is shaping the next generation of soft, intelligent surgical instruments.
