Device for injecting a viscous material into a hard tissue

Abstract

An injection system for injection of a relatively high viscous material into hard tissue surrounded by soft tissue in an animal body. The injection system comprising an elongated tubular member having a proximal section defining a syringe chamber and a distal section defining a cannula. The cannula having an inside diameter and an outside diameter and a length sufficient for insertion into the hard tissue. The proximal section defining the syringe chamber having an inside diameter greater than the inside diameter of the cannula, the proximal section adapted to be inserted in the soft tissue. The cannula having a bore communicating with the syringe chamber. The injection system comprising a syringe fitted for insertion within the syringe chamber of the proximal section. The syringe having an open end for communicating with the bore of the cannula. The syringe adapted for containing the high viscous material to be injected through the open end and the bore into the hard tissue respectively whereby the injection of the high viscous material is facilitated.
