IDIR at the congress DGfB 2026 in Hamburg

On March 20 2026, Dr. Ratnadeep Pramanik presented his research at the Biomechanics Congress / DGfB 2026 in Hamburg, where he shared recent advances in the computational design and placement of braided endovascular (Contour) devices for brain aneurysm treatment. The presented work was conducted within the framework of the IDIR initiative.

His work introduces a finite element framework capable of accurately capturing physically realistic braided wire interactions, including true frictional contact between filaments and with the aneurysm wall.

The study highlights that, beyond material properties, friction plays a major role in device expansion, anchoring, and final placement, underscoring its importance in predictive in silico deployment and future device optimization.

This study marks a strong contribution toward more reliable and clinically relevant computational modeling in endovascular biomechanics.
