  • Embolization device
    Patent number: 6656200
    Abstract: This invention relates to an embolization device for occluding a vessel. This device includes a matrix made of a biocompatible and biopolymeric material and a radiopaque material, wherein the radiopaque material is interspersed in the biocompatible and biopolymeric material. The matrix can adopt a linear extended form or a folded relaxed form.
    Type: Grant
