Investigadores de ETH Zurich desarrollaron microrobots magnéticos capaces de navegar precisamente por los vasos sanguíneos para administrar fármacos fibrinolíticos directamente al trombo en un ACV.
El sistema utiliza navegación electromagnética con microcatéter comercial y gripper polimérico flexible.
Los ensayos en modelos vasculares de silicona y en animales grandes (cerdos, ovejas) demostraron control y liberación efectiva del fármaco. La ventaja teórica es que la concentración localizada de un medicamento reduce el uso de dosis a nivel sistémico y los efectos adversos (sobre todo, la hemorragia).
