About
Jan G. Grandjean is a pioneering researcher at the intersection of cardiovascular surgery and medical robotics, whose work has significantly advanced the field of minimally invasive cardiac interventions. His research centers on developing robotic systems that overcome the inherent limitations of minimally invasive surgery — particularly restricted access, reduced visibility, and diminished instrument control — to expand treatment options for high-risk patients previously deemed inoperable. Grandjean is perhaps best known for his development and investigation of the Robotically-Actuated Delivery Sheath (RADS), a system designed to improve precision during complex procedures such as transapical aortic valve implantation and mitral valve repair. His most cited work, a 2017 paper on model predictive control of RADS for beating heart compensation (34 citations), demonstrated how intelligent control systems could compensate for cardiac motion in real time — a critical challenge in beating heart surgery. His earlier 2014 preliminary study on RADS for aortic valve implantation (17 citations) laid important groundwork for this technology. Complementing these contributions, his exploration of ultrasound-guided stabilization further underscores his commitment to integrating imaging and robotics for safer, more precise cardiac care.
