Abstract
A device for injecting a high viscosity material into a cannula, comprising a container being non-compliant and having an outlet adapted to communicate with the cannula for transferring the high viscosity material thereto, a pressure applicator in fluid communication with the container, the pressure applicator defining a fluid flow path through which an incompressible fluid is displaceable, and a material-moving member interrupting the fluid flow path and defining an incompressible fluid receiving portion on one side thereof in communication with the fluid flow path and a high viscosity material receiving portion in communication with the outlet of the container on an opposed side. The material-moving member being displaceable by a pressure of the incompressible fluid acting thereagainst to force the high viscosity material out of the high viscosity material receiving portion of the container and into the cannula.
