Title
(EN) EMBOLISATION AGENT
(FR) AGENT D'EMBOLISATION
Abstract
(EN)
The present invention relates to vascular embolisation agents. The embolisation agent according to the invention is essentially characterised in that it consists of a mixture comprising a biocompatible polymer dissolved in a biocompatible solvent, and two radio-opacifying agents: a radio-opaque powder and a radio-opaque agent soluble in said biocompatible solvent. The invention can be used for performing injections via a catheter into a blood vessel in order to mechanically and/or biologically cause a temporary or permanent occlusion of this blood vessel.

La présente invention concerne les agents d'embolisation vasculaire. L'agent d'embolisation selon l'invention se caractérise essentiellement par le fait qu'il est constitué d'un mélange comportant un polymère biocompatible dissout dans un solvant biocompatible, et deux radio- opacifiants : une poudre radio-opaque et un agent radio-opaque soluble dans ledit solvant biocompatible. Application : réalisation d'injections au moyen d'un cathéter dans un vaisseau sanguin afin de provoquer mécaniquement et/ou biologiquement une occlusion temporaire ou durable de ce vaisseau sanguin.
