DEVICES AND METHODS FOR CERVIX MEASUREMENT
First Claim
1. A device for measuring a length of a cervix, comprising:
- an elongate measurement member extending along a longitudinal axis and including a measurement scale thereon;
a hollow member coaxial with and disposed over the elongate measurement member;
a flange offset from the longitudinal axis and attached to a distal end of the hollow member;
a handle attached to a proximal end of the measurement member; and
a locking mechanism configured, when locked, to fix the hollow member relative to the measurement member and, when unlocked, to allow the hollow member to slide along the measurement member and rotate about the longitudinal axis so as to place the flange in a desired position without moving the measurement scale.

Abstract
A device for measuring a length of a cervix includes an elongate measurement member, a hollow member, a flange, a handle, and a locking mechanism. The elongate measurement member extends along a longitudinal axis and includes a measurement scale thereon. The hollow member is coaxial with and disposed over the elongate measurement member. The flange is offset from the longitudinal axis and attached to a distal end of the hollow member. The handle is attached to a proximal end of the measurement member. The locking mechanism is configured, when locked, to fix the hollow member relative to the measurement member and, when unlocked to allow the hollow member to slide along the measurement member and rotate about the longitudinal axis so as to place the flange in a desired position without moving the measurement scale.

13. A method for measuring a length of a cervix, comprising:
-
holding a handle of a device, the device further comprising an elongate measurement member having a measurement scale thereon, a hollow member coaxial with and disposed over the elongate measurement member, and a flange attached to a distal end of the hollow member; rotating the hollow member about the elongate measurement member so as to place the flange at a desired orientation without rotating the measurement scale; advancing the device distally within a vagina until the flange contacts a cervix at an external uterine opening; advancing the measurement member distally within the vagina until a distal end of the measurement member contacts a cervical uterine junction at a formix vaginae; locking the measurement member relative to the hollow member by locking a locking mechanism on the handle; and observing a position of the hollow member with respect to the measurement member to determine a length of the cervix in the formix vaginae. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
