Abstract
A collagen-based composition including microcapsules of atelocollagen or of a mixture of atelocollagen and a polysaccharide, particularly glycosaminoglycan, suspended in a viscous biocompatible carrier solution. Together, the microcapsules and the viscous carrier solution preferably have a viscosity such that the composition may be injected, in particular as a continuous thread from a needle. Said composition is readily injectable and may be used as a soft or bony tissues filling material for, or as a system for the controlled delivery and release of biologically, cosmetically or pharmaceutically active substances.
