Embodiment Construction

[0161]The devices and methods described herein are intended to prepare and dilate vaginal tissue during labor so as to prevent pelvic floor damage, and vaginal and perineal lacerations. Some embodiments of the device can stretch the perineal tissue until the diameter of the vaginal introitus has reached a target diameter of approximately 10 cm, roughly the size of the fetal head. In some embodiments, the device is a mechanical dilator that penetrates the first 3-4 cm of the vagina, the introitus, and gradually expands the vagina from a resting diameter of 2-3 cm to a fully expanded diameter equal to the size of the delivering fetus, approximately 10 cm. Expansion can be controlled either manually or via an automatic actuation system, and the device can be quickly collapsed and removed if needed.

[0162]The devices described herein can be inserted during the first phase of labor and removed just prior to the second phase of labor, allowing the rest of the birthing process to proceed as...

Abstract

A vaginal dilation device is provided that may include any of a number of features. One feature of the vaginal dilation device is that it is configured to dilate vaginal tissue during labor to prevent tissue damage. Another feature of the vaginal dilation device is that it can be manually controlled to dilate vaginal tissue, or can be automatically controlled to dilate vaginal tissue. In some embodiments, the vaginal dilation device is configured to measure a force applied by the device to tissue. In other embodiments, the vaginal dilation device is configured to apply a constant force to tissue. In other embodiments, the vaginal dilation device is configured to expand at a constant rate. Methods associated with use of the vaginal dilation device are also provided.
