Title: Devices and methods for cervix measurement

Abstract: A device for measuring a length of a cervix includes 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 on the handle. The hollow member is freely rotatable about the longitudinal axis relative to the measurement member to place the flange in a first position and in a second position perpendicular to the first position without moving the measurement scale. 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 axially along the measurement member in the first and second positions.
