1. An intrauterine catheter for measuring intrauterine pressure comprising:
- (a) an elongated flexible catheter tube having a uterine end and a gauge end for providing a liquid coupling from a uterus to a suitable pressure measuring device;
(b) a flexible membrane member enclosing the uterine end of said flexible catheter tube, said flexible membrane member includes a rigid structure for supporting at least a portion of said membrane member;
(c) a hollow filling tube fitted within said catheter tube extending to substantially the uterine end of the said catheter tube;
(d) a pressure measuring device having a first input and a second input, said pressure measuring device connected to said gauge end of said catheter tube.

Abstract
An intrauterine catheter is disclosed employing a catheter tube closed at one end by a flexible membrane, and connected at its other end to the input of a pressure transducer. The catheter is filled by injection of a sterile solution through the flexible membrane into the catheter tube or by pre-filling. The pressure measuring system is capable of being zeroed while the catheter is in place in the uterus.
