To design and mechanically evaluate a braided nickel-titanium stent retriever tailored for the distinct anatomical requirements of cerebral venous sinus thrombosis.
Designed a manually adjustable braided nickel-titanium (NiTi) stent retriever providing dynamic control over radial force and clot capture.
Performed finite element analysis to assess stress distribution under tensile, compressive, and bending conditions.
Conducted mechanical flexibility testing and evaluated deployment behavior within an in vitro anatomical human venous sinus model.
Finite element analysis demonstrated uniform stress distribution across tensile, compressive, and bending loads.
Mechanical testing confirmed low radial expansion force alongside high device flexibility.
Model deployment showed excellent wall conformability within complex venous sinus geometry.
