Abstract
According to an aspect of the invention, injectable bulking compositions are provided which contain the following: (a) fibers that are configured to prevent migration to locations in the body remote from the injection site, for example, because they have a minimum length that is sufficiently large to prevent migration of the fibers and/or because they have surface features that stimulate host tissue response to lock the fibers in position and (b) a carrier in an amount effective to render the composition injectable.
Claims15
An injectable bulking composition comprising:
- (a) fibers that are configured to prevent migration of the fibers to locations in the body remote from the injection site, and (b) a carrier in an amount effective to render the composition injectable, wherein said fibers are biodisintegrable fibers that comprise a polymer selected from polyvinyl alcohol homopolymers and copolymers, polyvinylpyrrolidone, and salts thereof.
