A system for delivering an injectable material to a site within a mammal, the system comprising a cannula and a needle. The cannula defining an aperture in a side wall thereof and comprising an angled ramp platform disposed within the cannula proximate to the aperture that extends proximally and inwardly away from proximate the distal end of the aperture. The needle is longitudinally movable within the cannula between a withdrawn position, at which a tip of the needle is stored within the cannula, to an extended position, at which the tip of the needle extends through the aperture of the cannula a predetermined distance from the side wall of the cannula. In one aspect, the system also includes a supply of injectable biocompatible bulking composition for controlling vesicoureteral reflux that is operatively connected to the needle. |
