ABSTRACT:
A catheter device is described for the localized introduction of pharmaceutical material into the uterine cervix and the upper vagina. In one embodiment the catheter device comprises a flexible tube having a port at the proximal end and a rounded closed tip and an aperture away from the tip at the distal end. A diaphragm having a hole through which the tube may pass is used to seal off the cervix and upper vagina from the lower vagina, and a syringe is used to administer the pharmaceutical material through the port in the flexible tube. In a second embodiment two ports are provided in the flexible tube, enabling a flushing material to be ejected into the tube after the pharmaceutical material, thus ensuring that the entire dose of pharmaceutical material is delivered to the cervix and the upper vagina.
