3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters
Advanced Robotics Research, EarlyView.This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

An investigation into the influence of stent strut thickness on in-stent restenosis using the finite element method [PDF]
, 2005 In-stent restenosis represents the major limitation for stenting procedures. In-stent restenosis is the renarrowing o f the artery lumen within a stent predominantly due to excessive growth of neointimal hyperplasia.

“Bendy” stents help negotiate hairpin intracardiac curves [PDF]
, 2015 Simple transposition of the great arteries (TGA) occurs in 0.2 per 1000 live births. The condition is surgically repaired in the neonatal period by the arterial switch procedure (ASO) sometimes preceded by an atrial septostomy.

Optimization of Magnetic Milli‐Spinner for Robotic Endovascular Intervention
Advanced Robotics Research, EarlyView.This work presents the design optimization of a multifunctional magnetic milli‐spinner for high‐speed propulsion and efficient clot debulking. The optimized design achieves an ultrafast swimming velocity of 55 cm/s (≈175 body lengths/s) in saline water, enabling stable upstream swimming against strong physiological flows and establishing magnetic milli‐
