Abstract[English]
A shape memory polymer scaffold for treatment of a fistula. The scaffold is formed from a shape memory polymer foam that can be triggered to expand from a compressed shape to an expanded shape in response to hydration and/or heating. The shape memory polymer foam includes an antibacterial component and a biodegradable component so that the scaffold addresses infective agents in the fistula and will degrade over time as the fistula heals. The foam may comprise poly(vinyl alcohol), starch, and a phenolic acid.[French]
L'invention concerne un échafaudage polymère à mémoire de forme pour le traitement d'une fistule. L'échafaudage est formé à partir d'une mousse polymère à mémoire de forme dont l'expansion peut être déclenchée pour passer d'une forme comprimée à une forme expansée en réponse à une hydratation et/ou à un chauffage. La mousse polymère à mémoire de forme comprend un composant antibactérien et un composant biodégradable de telle sorte que l'échafaudage agisse sur des agents infectieux dans la fistule et se dégrade au fil du temps à mesure que la fistule guérit. La mousse peut comprendre un poly(alcool de vinyle), de l'amidon et un acide phénolique.
