Abstract

The present application provides a medical device (10) for measuring cervical dilation including an elongate body (12) defining a proximal end (19) and a distal end (16), as well as an expandable element coupled to the distal end of the elongate body. An array of movable (24) 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 (36). 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.

Claims (13)

1. A cervimetry device for measuring cervical dilation, comprising:
an expandable element;
an inflation source in communication with the expandable element;
an array of contact elements movably disposed about an exterior circumference of the expandable element; and a control element for controlling the inflation source and indicating a cervical dilation measurement.
2. (Cancelled)
3. The cervimetry device according to Claim 1, further comprising at least one pressure sensor mounted on at least one of the contact elements, the pressure sensor being in communication with the control element.
4. The cervimetry device according to Claim 1, further comprising an exhaust valve in fluid communication with the expandable element, wherein the exhaust valve is also in communication with the control element.
5. The cervimetry device according to Claim 1, wherein the control element includes a display.
6. The cervimetry device according to Claim 1, wherein the control element includes a control actuator for receiving input from a user.
7. The cervimetry device according to Claim 1, wherein the control element includes an electronic storage medium.
8. The cervimetry device according to Claim 1, further comprising an elongate body defining a proximal end and a distal end, wherein the expandable element is movably coupled to the distal end of the elongate body, and the control element is coupled to the proximal end of the elongate body.
9. The cervimetry device according to Claim 8, further comprising a distal pad coupled to the distal end of the elongate body.
10. The cervimetry device according to Claim 9, further comprising a distal pressure sensor coupled to the distal pad, wherein the distal pressure sensor is in communication with the control element.
11. The cervimetry device according to Claim 8, further comprising a camera coupled to the distal end of the elongate body, wherein the camera is in communication with the control element.
12. The cervimetry device according to Claim 8, further comprising a lighting element coupled to the distal end of the elongate body, wherein the lighting element is in communication with the control element.
