Abstract
A composition suitable for implantation in soft tissue (for example at or around a body orifice) in order to augment the volume of soft tissue is produced. The particles, which are desirably irregularly shaped, are formed from a biodegradable phosphate glass, and may have an average particle diameter of 50 &mgr;m to 2000 &mgr;m, preferably 50 &mgr;m to 300 &mgr;m. The particles are used with a carrier medium for injection into soft tissue such as the bladder submucosa. This procedure can be applied to treat conditions such as vesicoureteric reflux. Additionally the procedure could be used cosmetically.
