| abstract |
it is an embolization microcatheter that is configured to distribute embolization particles in a target area and minimize or prevent embolization from a non-target area. the microcatheter includes a section, located between the distal and proximal ends of the microcatheter, which has a frame formed by twisted wires and a polymeric layer interspersed and / or superimposed on the frame. this section includes a plurality of axial slits, with each slit having a smaller cross-sectional dimension configured to prevent the efflux of the embolization particles. |
