CERVICAL DILATOR AND METHODS OF USE

摘要

In one embodiment, a cervical dilator includes a tubular member having a rounded cap disposed at the distal end, a balloon disposed on the distal portion, a lumen extending longitudinally within the tubular member, and a flexible wire attached to the wall of the lumen. The cervical dilator may be extended inside the uterus of a patient for sounding, and the tubular member will bend but not snap if excessive pressure is applied against a uterine wall, sliding away from the point of contact. The balloon is then properly positioned inside the cervical canal and gradually inflated. In other embodiments, a plurality of tubular members may be included, each reciprocating within another, and one or two applicator members may also be provided, to retain the cervix in position before and after dilation.
