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.

Ocular Findings as the Most Striking Manifestation of a SMAD3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Loeys‐Dietz syndrome (LDS) is a heritable connective tissue disorder with variable expressivity. It is a multisystemic condition mainly characterized by a propensity for arterial aneurysms and dissections, skeletal manifestations, hypertelorism, bifid uvula, craniosynostosis, and cutaneous features.
