ABSTRACT:
The present invention is an improved balloon catheter for cervical dilation having a shape when inflated that is larger in diameter at the portions of the balloon that extend into the cervix and vagina, and is narrower in diameter at the middle, or cervical portion. This improved shape of the inflated catheter allows an easier and simplified placement of the catheter in a patient and retention of the catheter in position during cervical dilation.
