Abstract: Minimally invasive medical procedures, such as endovascular catheterization, have drastically reduced procedure time and associated complications. However, brain microvasculature, still remain inaccessible due to the lack of appropriate guidance technologies, which does not allow deploying microscopic structures. Namely, the increased flexibility of miniaturized slender structures, cannot withstand the push forces exerted by the surgeon and results in buckling. In this talk, a new method for soft robot navigation that harnesses hydrokinetic energy for transportation and magnetic fields for steering is presented. Exploiting elasto-hydrodynamic coupling allows bypassing the current flexibility-rigidity trade-off bottleneck while enabling navigation of cell-sized robots with cross-sectional area that are orders of magnitude smaller than the smallest microcatheter currently available. I will show that tethered ultra-flexible endovascular microscopic robots can be navigated through tortuous vascular networks with minimal external intervention, unprecedented speed and by promoting safe and autonomous robotic guidance of multileads.

Bio: Lucio Pancaldi obtained his BSc in Life Sciences and MSc in Bioengineering at EPFL in 2013 and 2017, respectively. He conducted his master thesis in Prof. Melody Swartz lab at the University of Chicago, where he investigated the development optical biosensors using liquid crystals and diamond-based solid-state quantum technologies. He joined the MicroBioRobotic Systems Lab (MICROBS) in 2018 as a graduate student. His current PhD work focuses on endovascular microscale technologies and associated navigation methods for fundamental neuroscience and translational medicine.
