Compositions for tissue augmentation

The embodiments set forth herein provide biocompatible self-setting compositions suitable for use in tissue augmentation applications. The biocompatible self-setting compositions described herein exhibit advantageous theological properties and may be applied to a site in the body of a patient by injecting the composition through a 20-30 gauge needle. Once applied to a site in the body, the composition sets to a slow resorbing or substantially non-resorbing matrix. Advantageously, exposure of the composition material to body heat at its site of use enhances setting of the composition. Composition materials prepared in accordance with the present disclosure may find use in applications involving, for example, soft tissue augmentation such as for dermal fold augmentation, prevention of adhesions, soft tissue void filling, soft tissue bleb creation, urethral sphincter augmentation for treatment of urinary incontinence, treatment of unilateral vocal fold paralysis, and lower esophageal sphincter augmentation for treatment of gastroesophageal reflux disease. In some embodiments, the presently described biocompatible compositions may serve as bone void fillers.
