Hysterosalpingography and fallopian tube cannulation: use of a double-balloon introducing catheter.

A double-balloon introducing catheter for cervical cannulation is described. The catheter can be used for hysterosalpingography and allows coaxial passage of a 5-F curved catheter to selectively catheterize the fallopian tubes. The device has been used successfully in eight patients and may offer several advantages over other currently available equipment.
