BULKING OF SOFT TISSUE

摘要

A soft tissue bulking material includes a plurality of particles. Each particle comprises a rounded polymeric shell defining an internal cavity and having a maximum outer dimension of 50µm - 250 µm. A port or opening is provided in the shell. The port or opening thus provides access to the cavity. The port or opening has a size or dimension that ranges from one tenth of the particle's outer dimension up to the particle's outer dimension.
