Cervical dilator catheter

This invention is an improved balloon catheter for cervical dilation. This catheter has a balloon that is passed through the cervix of a pregnant woman, and the balloon is then inflated with 100-120 ml of sterile water or normal saline. The improved disc shape of the inflated balloon is 8 cm in diameter and 3-4 cm in height. The balloon will sweep the amniotic membrane away from the cervix, causing the release of prostaglandins which helps ripen the cervix and initiates uterine contractions. The improved shape of the balloon causes the cervix to be 6-8 cm dilated once it is expelled. This catheter also contains a flexible guidewire that allows for easier insertion for the provider, and makes insertion less painful for the patient because it can be placed without a speculum and ring forcep being used. This catheter could actually be placed on an outpatient basis or in the doctor's office, with the patient instructed to go to the hospital or birthing unit when the catheter falls out. This catheter is smaller in diameter than the 16 French Foley catheter, so therefore it can be placed when the patient is <1 cm dilated. This catheter when placed properly and secured to the patient's thigh with tension applied can shorten labor by 4-10 hours.

Method and apparatus for providing contraction information during labour

A method and apparatus for implementing a user interface for displaying uterine contraction information is provided. The contraction signal is processed to derive a sequence of contraction persistence indices. Each contraction persistence index in the sequence is associated to a portion of the contraction signal and conveys whether there is an excess in the rate of contraction in the associated portion of the contraction signal. If there is an excess in the rate of contraction in the associated portion of the contraction signal, the contraction persistence index conveys whether this excess is part of a sustained pattern of excess in the rate of contractions or whether the excess is likely to be transient. The sequence of contraction persistence indices is displayed to a user. Optionally, the graphical user interface is adapted for selectively causing an alarm event based at least in part on the sequence of contractility persistence indices.
