A flexible tube designed for the intrauterine injection of an opaque tracer medium, to facilitate radiography of the fallopian tubes/uterus (salpingography/ hysterosalpingography), and/or a saline solution, to enhance transvaginal ultrasonography (TVUS) [saline infused sonography (SIS)/ hysterosonography]. It is typically a duel lumen tube, with a non-latex inflatable cuff (balloon), pad or cap near the distal tip intended to seal the cervix, and may include devices dedicated to catheter function (e.g., stylet, syringe). This is a single-use device.
