Abstract
An improved biocompatible composition consisting of physiologically stable microparticles carried in a lubricative suspension, solution, other fluid or gel is presented. The composition is intended to be delivered into the body through a small-bore needle, cannula, or catheter and to a tissue site for the purpose of augmenting the tissue site and surrounding area, thereby correcting a defect, filling a void, or strengthening the support structures of the tissue. The particles are a hard, metallic substance and are carbon-coated.
Claims23
An injectable, biocompatible composition for tissue augmentation comprising:
- a plurality of discrete particles in a carrier, wherein the particles are substrate particles with a carbon coating and have an average, transverse cross-sectional dimension of between 100 and 1,000 microns and the carrier is a biocompatible medium having sufficient fluidity to carry and deliver the particles, and has lubricative qualities.
A method for augmenting tissue in a human patient comprising injecting into a tissue site in the patient a composition comprising a plurality of discrete, carbon coated substrate particles having an average, transverse, cross-sectional dimension of between 100 and 1,000 microns in a biocompatible carrier having sufficient fluidity to carry and deliver the particles and lubricative qualities.
