Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents
Advanced Healthcare Materials, EarlyView.Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Tunable Applicator for Microneedle‐Based Medical Devices
Advanced Materials Technologies, EarlyView.This paper presents a simple, low‐cost tunable applicator (TAPP) for microneedle array patches that uses a material‐agnostic controlled‐fracture mechanism to ensure reliable skin penetration and uniform array engagement. The scalable, modular design is compatible with injection molding and 3D printing, can be integrated directly into patches, and is ...
