  • Patent number: 4543965
    Abstract: There is provided a device for measuring intrauterine pressure during prency and during labor prior to the rupture of the amniotic membrane. The device comprises an elongated catheter having a uterine end and an instrumentation end, and is introducible with its uterine end into the uterus. The catheter has at least one deformable membrane inflatable by means of a fluid, which membrane is fixedly attached to and, in its noninflated state, substantially closely surrounds, a portion of the catheter substantially contiguous with the uterine end. There is also provided pressure-transmitting means located at said uterine end and at least one conduit, leading from a first end located remote from the uterine end to a second end opening to the outside of the catheter at a point within the membrane-surrounded portion. The first end is fittable with first flow-control means. A method for utilizing this device is also described.
