<p>A medical device (20) which includes an elongate probe member (22) sized to be able to enter a urethra of a female human body and having a length so that when the distal extremity (22b) is disposed in the vicinity of a target volume of tissue surrounding the urethra the proximal extremity is outside of the urethra. The elongate probe member (22) has a passage (31) extending from the proximal extremity (22a) to the distal extremity (22b). At least one tubular needle (41) is disposed in the passage (31) and has first and second extremities (41a, 41b) and a flow passageway (42) therein extending longitudinally from the first extremity (41a) to at least one opening (43) provided in the second extremity (41b) of the at least one tubular needle (41). A control handle (61) is secured to the proximal extremity (22a) of the elongate probe member (22) for causing movement of the at least one tubular needle (41) in the passage (31). A guide passageway (58) causes movement of the at least one tubular needle (41) through a curved path extending at an angle to the longitudinal axis (27). A supply assembly (96) is carried by the proximal extremity (22a) of the elongate probe member (22) and is in communication with the flow passageway (42) of the at least one tubular needle (41) for introducing an agent into the flow passageway (42). A method for use of the device (20) is provided.</p> |
