About

Rosario Obregon is pioneering the next generation of minimally invasive surgical tools, with a focus on endovascular surgery and continuum robotics. Her most cited work introduces the **VINE Catheter** (2021, 60 citations), a novel device designed to navigate the highly tortuous and angulated vascular anatomy that makes procedures like stroke and aneurysm treatment so challenging. This innovation directly addresses the risks and lengthy procedure times associated with traditional catheters. Complementing this hardware breakthrough, Obregon’s research on **closed-loop position control for growing robots** (2021, 20 citations) tackles a fundamental problem in continuum robotics: maintaining precise navigation during frequent, unpredictable interactions with the environment. By developing online Jacobian corrections, she enables these compliant robots to adapt in real-time, significantly improving their safety and reliability in confined spaces. Her work bridges critical gaps between device design and intelligent control, laying the groundwork for faster, safer, and more accessible endovascular interventions.
