Title: Enhanced carriers for the delivery of microparticles to bodily tissues and fluids

Abstract: Improved compositions for tissue augmentation are provided. These compositions comprise an amount of crosslinked material sufficient to provide a melt temperature (T.sub.m) greater than 37C, wherein microparticles can be substantially uniformly dispersed and maintained at ambient room temperature as well as body temperature. Said compositions also provide high shear moduli, sufficient to effectively deliver microparticles into dense tissue and narrow intersticial spaces without significant disruption to the homogeneous distribution of microparticles within the solution. The provided compositions can be stored and shipped at room temperature without significant detriment to the material composition. Additional embodiments include a system for delivery of tissue augmentation materials and methods of manufacture thereof.
