Patent

CA 2745903

An apparatus and system for providing reduced pressure to a defect in a nerve is disclosed. The apparatus comprises a nerve conduit having a generally tubular shape that has walls including a luminal wall surrounding the tissue site to contain fluids within a luminal space between the tissue site to contain fluids within a luminal space between the tissue site and the luminal wall. The apparatus further comprises a manifold having a porous body and a connector for receiving reduced pressure, wherein the manifold is positioned within the luminal space adjacent the tissue site to distribute the reduced pressure to the defect. Additionally, a method for providing reduced pressure to a defect in a nerve is disclosed that includes implanting the nerve conduit and manifold at a site of damaged nerve tissue and applying a reduced pressure to the manifold thereby stimulating repair or regrowth of nerve tissue.

L'invention porte sur un appareil et un système pour appliquer une pression réduite à une anomalie dans un nerf. L'appareil comprend un conduit nerveux de forme généralement tubulaire qui a des parois comprenant une paroi luminale entourant le site du tissu pour contenir des fluides à l'intérieur d'un espace luminal entre le site du tissu et la paroi luminale. L'appareil comprend en outre un collecteur comportant un corps poreux et un connecteur pour recevoir une pression réduite, le collecteur étant positionné à l'intérieur de l'espace luminal adjacent au site du tissu pour distribuer la pression réduite à l'anomalie. De plus, l'invention porte sur un procédé de distribution d'une pression réduite à une anomalie dans un nerf, le procédé comprenant l'implantation du conduit nerveux et d'un collecteur au niveau d'un site d'un tissu nerveux lésé et l'application d'une pression réduite au collecteur, stimulant ainsi la réparation ou la régénérescence du tissu nerveux.
