A medical treatment device comprising an elongate probe member having proximal and distal extremities. The elongate probe member has a longitudinal axis and at least one passageway extending from the proximal extremity to the distal extremity. A guide is mounted in the at least one passage of the elongate probe member and has proximal and distal extremities with the distal extremity of the guide being in the vicinity of the distal extremity of the elongate probe member. The guide has an opening in the distal extremity and a lumen extending from the proximal extremity to the opening in the distal extremity. A needle is slidably disposed in the lumen of the guide. The needle is in the form of a tube having an axial lumen extending therethrough. A control mechanism is coupled to the proximal extremity of the elongate probe member and is secured to the needle for advancing and retracting the needle relative to the guide.
