Selectively Actuated Fiberbots for High-precision Minimally Invasive Surgery
Jinshi Zhao, Libaihe Tian, Alex Ranne +9
Long, slender instruments are essential for minimally invasive surgery (MIS), but achieving precise distal manipulation becomes increasingly difficult when actuation extends along…
A Mapping Sheath with Thermally Drawn Multi-Electrode Basket for Cardiac Electrophysiological Recording and Ablation Catheter Delivery
Qindong Zheng, Anil Demircali, Jinshi Zhao +14
Cardiac arrhythmias, particularly atrial fibrillation, represent a major cardiovascular health burden and underscore the need for efficient and integrated strategies for electrical…
A Paradigm Shift in Catheter Development: Thermally Drawn Polymeric Fibers for MR-Guided Cardiovascular Interventions
Mohamed E. M. K. Abdelaziz, Libaihe Tian, Thomas Lottner +9
Cardiovascular diseases (CVDs) and congenital heart diseases (CHD) pose significant global health challenges. Fluoroscopy-guided endovascular interventions, though effective, are a…
CathSim: An Open-source Simulator for Endovascular Intervention
Tudor Jianu, Baoru Huang, Mohamed E. M. K. Abdelaziz +6
Autonomous robots in endovascular operations have the potential to navigate circulatory systems safely and reliably while decreasing the susceptibility to human errors. However, th…
End-to-End Real-time Catheter Segmentation with Optical Flow-Guided Warping during Endovascular Intervention
Anh Nguyen, Dennis Kundrat, Giulio Dagnino +7
Accurate real-time catheter segmentation is an important pre-requisite for robot-assisted endovascular intervention. Most of the existing learning-based methods for catheter segmen…
