CA 2699685

The invention provides biocompatible polymeric hydrogel matrices having excellent durability and swellability. The matrices are formed from a combination of linear and branched hydrophilic macromer compounds. The matrices can be used in association with a medical device or alone. In some methods the polymeric matrix is placed or formed at a target site in which the matrix swells and occludes the target area.

L'invention concerne des matrices d'hydrogel polymériques biocompatibles ayant d'excellentes durabilité et aptitude à gonfler. Les matrices sont formées à partir d'une combinaison de composés macromères hydrophiles linéaires et ramifiés. Les matrices peuvent être utilisées en association avec un dispositif médical ou seules. Dans certains procédés la matrice polymérique est placée ou formée au niveau d'un site cible dans lequel la matrice gonfle et occlut la zone cible.
