Abstract
This invention relates to bioactive sol-gel derived silica fibers, methods for their preparation, an implantable device comprising the fibers and the use of the device for tissue guiding or bone repair.
Claims21
A method for the preparation of a bioactive silica fiber, said method comprising spinning a solution containing silica polymers to form a fiber, wherein the starting point of said spinning step corresponds to a solution viscosity of at least 2000 cP, followed by (i) heat treating or ii) aging of the fiber.
A bioactive silica fiber spun from a solution containing silica polymers at a starting point of a spinning process corresponding to a solution viscosity of at least 2000 cP, after which said fiber has been subjected to i) heat treatment or ii) aging.
