ABSTRACT:
A catheter for non-surgical entry into the cervical canal or the uterus, comprising an elongated tubular catheter body. An inflatable balloon manufactured from a polyurethane material is disposed proximal to the distal end of the catheter body. The polyurethane inflatable balloon can be progressively inflated into an elliptical shape which enables the balloon to be used within the cervical canal. Additional inflation pressure inflates the polyurethane inflatable balloon to a spherical shape which enables the balloon to be used within the uterus.
