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.
