There is provided 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. The composition described comprises particles of a, preferably water-soluble, biodegradable glass in a suitable carrier medium, such as glycerol. The particles, which are desirably irregularly shaped, may have an average particle diameter of from 50 m to 2000 µm, preferably 50 µm to 300 µm. By injecting the particles into soft tissue, for example the bladder submucosa, it is possible to bulk up the soft tissue where this is required. This procedure can be applied to treat conditions such as vesicoureteric reflux. Additionally the procedure could be used cosmetically.
L'invention porte sur une composition implantable dans des tissus mous (par exemple sur ou autour d'une ouverture du corps) destinée à accroître le volume des tissus mous. Ladite composition comporte des particules, de préférence de verre hydrosoluble et biodégradable, dans un excipient approprié tel que du glycérol. Les particules qui sont à dessein irrégulières peuvent présenter un diamètre moyen de 50 à 2000 mu m et de préférence de 50 à 300 mu m. L'injection de telles particules dans des tissus mous, par exemple de la sous-muqueuse de la vessie, si elle est nécessaire permet de faire gonfler les tissus. Cette technique qui peut s'appliquer au traitement d'états tels que le reflux vésico- urétérique peut également servir en cosmétologie.
