Strategic Design of Soft Actuators in Translational Medical Robotics for Human‐Centered Healthcare

Advanced Robotics Research, EarlyView.
Soft robotics enables biocompatible, compliant medical devices, but clinical translation requires design‐driven engineering beyond materials. This perspective reviews implantable, surgical, and wearable systems by actuation mechanism, highlighting how optimized architectures and integration improve mechanical interfacing, adaptability, and durability ...

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‐

Safety and feasibility of simultaneous left and right heart catheterization via single-arm arterial and venous access

, 2022
Background: Catheterization via the radial artery has become the method of choice for evaluation of the coronary arteries; however in patients requiring simultaneous coronary and right heart catheterization upper extremity access is not commonly used ...

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

Isolated right pulmonary artery discontinuity [PDF]

, 2000
Unilateral “absence” of the pulmonary artery is an uncommon malformation frequently associated with congenital heart disease. In fact, the pulmonary artery is typically discontinuous from the main pulmonary artery, not absent.

Sex differences in use of interventional cardiology persist after risk adjustment. [PDF]

, 2008
BACKGROUND: Studies from several countries have documented gender disparities in the management of coronary artery disease. Whether such gender disparities are seen in Italy and, if so, whether they can be explained by factors such as age and severity of
