Tóm tắt

 Cerebral venous sinus thrombosis (CVST) is frequently observed in younger adults and features in large thrombus volume. Due to the triangular-like cross-sectional shape and large diameter of the superior sagittal sinus, all the commercially available artery stent retrievers are not suitable for venous vessels. In this study, a dumbbell-like stent was designed and fabricated by 3D braided technology using NiTi wires
  it was manually rotatable and stretchable with controlled length/diameter ratios (2.6-14.0) and reciprocating maneuverability. Computational modeling and an
