A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

Advanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics

Advanced Intelligent Systems, EarlyView.
Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.

Parametric Design of Continuum Robots Using Interlocking Ball Joints

Advanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

Collaborative Multirobot Navigation‐Assisted Magnetic Catheter Guidance and Shape Perception with Vascular Ultrasound and Electromagnetic Tracking

Advanced Intelligent Systems, EarlyView.
The article develops a collaborative multirobot navigation system‐assisted magnetic catheter guidance and shape perception method using the information fusion of robotic vascular ultrasound imaging and electromagnetic tracking to reconstruct the 3D catheter's shape and vasculature. Results verify the effectiveness of the system and the potential of the
