Abstract[English]
Presented herein are cured ring seals and related methods for at least temporarily sealing openings in fluidically-sealed body chambers. The cured ring seals include a body that is formed from a hydrophilic or hygroscopic polymer, such as polyvinyl alcohol (PVA), that is cured prior to implantation into the body of a recipient (e.g., pre-cured). The cured ring seals are substantially pliable to facilitate positioning around an outer surface of an implantable component and are configured to expand following implantation.[French]
La présente invention concerne des joints annulaires durcis et des procédés associés pour sceller de manière étanche et au moins temporairement des ouvertures dans des chambres de corps scellées de manière étanche aux fluides. Les joints annulaires durcis comprennent un corps qui est formé à partir d'un polymère hydrophile ou hygroscopique, tel que le poly(alcool de vinyle) (PVAL), qui est durci avant l'implantation dans le corps d'un receveur (par exemple, pré-durci). Les joints annulaires durcis sont sensiblement souples pour faciliter le positionnement autour d'une surface externe d'un composant implantable et sont configurés pour se dilater après implantation.
