Membrane to re-establish continuity of injured biological tissues

Abstract

A membrane for re-establishing the continuity of injured biological tissues includes a non-woven fabric of fibres of a polyhydroxyalkanoate (PHA) containing 3-hydroxybutyrate monomer units, wherein the fibers have an average diameter between 800 nm to 3500 nm. Preferably, the PHA is a poly-3-hydroxybutyrate homopolymer and at least one active ingredient is associated with the fibers of the non-woven fabric. The membrane has the advantages of promoting the healing of injured biological tissues relatively quickly, without inducing excessive inflammatory or rejection reactions, thus demonstrating a high biocompatibility, thereby providing a valid support in the healing process of biological tissue injuries and preventing the formation of dehiscences and incisional hernias.
