ABSTRACT:
A device for delivering small spheres of biomaterial into a determined portion of a bone including a cylindrical hollow body of inside diameter D1having a filling first end and a second end provided with a snap-fastener, a shutter-forming guide rod having a main portion that is cylindrical with an outside diameter D2and presenting an enlarged cylindrical portion suitable for co-operating with the snap-fastener of the body, and a piston constituted by a cylindrical part presenting an outside diameter D3and an axial bore of diameter D4. The diameter D3is slightly smaller than the inside diameter D1of the body and the inside diameter D4is slightly greater than the diameter D2of the rod in such a manner that, once the snap-fastener has been released, the rod can slide inside the piston, and the piston can slide inside the body.
