A micro-transducer catheter was tested in vitro and in vivo for recording of myometrial activity in the non-pregnant human uterus and was also compared with conventional fluid-filled, open end catheters previously used for recording intra-uterine pressures. The micro-transducer catheter had a frequency response far above that of fluid-filled, open end catheters. It was easily introduced through the uterine cervix and was never obstructed. Provided that the sensory surface of the micro-transducer was kept from direct contact with the uterine wall by some special arrangement it gave recordings of the intra-uterine pressure, that were practically identical with those obtained by an open end catheter.
