Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

Advanced Materials Technologies, EarlyView.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

Novel Vascular‐Adaptive Liquid Metal Microspheres Enable Visualized Arterial Embolization Therapy

Advanced Science, EarlyView.
We present drug‐loaded liquid metal microspheres (X‐MEN) as a novel agent for image‐guided arterial embolization. With inherent radiopacity and superior deformability, X‐MEN enables real‐time monitoring and conforms tightly to irregular vessels. This approach ensures precise, long‐lasting embolization without recanalization, addressing critical ...
