A permanent, biocompatible material for soft tissue augmentation. The biocompatible material comprises a matrix of smooth, round, finely divided, substantially spherical particles of a biocompatible ceramic material, close to or in contact with each other, which provide a scaffold or lattice for autogenous, three dimensional, randomly oriented, non-scar soft tissue growth at the augmentation site. The augmentation material can be homogeneously suspended in a biocompatible, resorbable lubricious gel carrier comprising a polysaccharide. This serves to improve the delivery of the augmentation material by injection to the tissue site where augmentation is desired. The augmentation material is especially suitable for urethral sphincter augmentation, for treatment of incontinence, for filling soft tissue voids, for creating soft tissue blebs, for the treatment of unilateral vocal cord paralysis, and for mammary implants. It can be injected intradermally, subcutaneously or can be implanted.
A biocompatible, resorbable, lubricous carrier for suspending a particulate ceramic in a tissue augmentation material, comprising a polysaccharide gel, wherein the polysaccharide gel maintains the particulate ceramic homogeneously suspended in the tissue augmentation material prior to augmentation of a desired tissue site and during introduction of the tissue augmentation material to the desired site.
A biocompatible composition for augmenting tissue, comprising a particulate ceramic material for augmenting a desired tissue site and a biocompatible, resorbable, lubricous carrier for the particulate ceramic, the carrier comprising a polysaccharide gel, wherein the carrier maintains the particulate ceramic homogeneously suspended in the biocompatible composition prior to augmentation of a desired tissue site and during introduction of the biocompatible composition to the desired site.
In a biocompatible composition for augmenting tissue, the biocompatible composition comprising a particulate ceramic for augmenting a desired tissue site and a biocompatible, resorbable, lubricous carrier for the particulate ceramic, the improvement comprising a polysaccharide gel carrier, the carrier maintaining the particulate ceramic homogeneously suspended in the biocompatible composition prior to augmentation of a desired tissue site and during introduction of the biocompatible composition to the desired site.
A carrier for suspending a particulate ceramic in a tissue augmentation material, comprising a polysaccharide gel, the polysaccharide gel maintaining the particulate ceramic homogeneously suspended in the tissue augmentation material prior to augmentation of a desired tissue site and during introduction of the tissue augmentation material to the desired site.
