A method of making a porous bioresorbable dressing is provided for use in applying reduced pressure therapy to a wound site. The process includes manufacture of a dressing by use of one or more bioresorbable polymers and a porogen system. The malleability of the dressing allows the dressing to be placed into the wound site such that it fills the shape and size of the wound. Embodiments include use of hand molding and formation of a rope dressing. The porogen system may be activated external to the wound site or formed in situ within the wound site, thus creating a porous dressing. A reduced pressure delivery tube is fluidly connected to the wound site to delivery a reduced pressure to the wound site.

L'invention concerne un procédé de fabrication de pansement biorésorbable poreux destinés à appliquer une thérapie par pression réduite sur un site de plaie. Ce processus comprend la fabrication d'un pansement au moyen d'un ou de plusieurs polymères biorésorbables et d'un système porogène. La maniabilité de ce pansement permet à ce pansement d'être placé dans le site de la plaie de sorte qu'ils remplisse la forme et la taille de celle-ci. Des modes de réalisation de l'invention concernent l'utilisation de moulage à la main et de formation d'un pansement cordon. Le système porogène peut être activé à l'extérieur du site de la plaie ou formé sur site à l'intérieur du site de la plaie, créant ainsi un pansement poreux. Un tube d'apport de pression réduite est fluidiquement connecté au site de la plaie afin d'apporter une pression réduite sur ce site.
