Method for cervical dilation and/or measurement
First Claim
1. A method for performing cervical dilation, comprising the steps of:
- providing a medical device having an array of movable elements disposed circumferentially about an axis;
positioning the medical device proximate a region of cervical tissue to be dilated; and
extending the array of movable elements to cause dilation of the cervical tissue.

Abstract
The present invention provides a medical device for measuring and/or providing cervical dilation including an elongate body defining a proximal end and a distal end, as well as an expandable element coupled to the distal end of the elongate body. An array of movable elements may be disposed circumferentially about the elongate body, where the array of movable elements is movably coupled to the distal end of the elongate body by a plurality of wires. The medical device may further include a measurement mechanism able to determine a radial spacing of the array of movable elements, as well as a dilation indicator in communication with the measurement mechanism. One or more pressure sensors may be coupled to the array of movable elements, whereby a control element is in communication with the pressure sensors. In addition, an inflation source may be included in fluid communication with the expandable element.
