Abstract: The present invention provides a medical device for measuring 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.

Abstract: The present invention provides a medical device for measuring cervical dilation, where the medical device is positionable about a hand having first and second fingers, with each finger having a tip and a side surface. The medical device may include a housing, a first extension element movably coupled to the housing, a second extension element movably coupled to the housing, and a dilation indication mechanism to measure a distance between the first and second extension elements. The medical device may also include a first lateral pressure sensor positionable about a side surface of the first finger, a second lateral pressure sensor positionable about a side surface of the second finger, a third pressure sensor positionable about a tip of the first finger, and a fourth pressure sensor positionable about a tip of the second finger.
