Device for injecting a viscous material into a hard tissue
First Claim
1. A device for injecting a relatively high viscous material into hard tissue surrounded by soft tissue in an animal body, the device 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 syringe chamber adapted to receive a syringe containing the high viscous material for injection through the bore into the hard tissue whereby injection of the high viscous material is facilitated.

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.

21. A method for injecting a viscous material through hard tissue surrounded by soft tissue in an animal body, the method comprising the steps of:
-
providing an elongated tubular member comprising a distal section defining a cannula adapted to be inserted into hard tissue with minimal damage, and a proximal section defining a syringe chamber having larger outer and inner diameters than the cannula;
inserting the cannula into the hard tissue, so that the proximal section remains outside of the hard tissue but at least partially within the soft tissue;
inserting a syringe pre-filled with the viscous material into the syringe chamber; and
using the syringe to inject the viscous material into the hard tissue through the cannula. - View Dependent Claims (22, 23)
