Abstract: A multi-lumen catheter for monitoring intrauterine pressure comprising an elongated body configured and dimensioned for insertion into a uterus of a patient, the catheter having a first lumen, a second lumen, and a first balloon at a distal portion. The first lumen communicates with the first balloon and the second lumen has an opening within the uterus for injection of x-ray dye or other fluid into the uterus for imaging the uterine cavity and the fallopian tubes of a patient. The first balloon contains a gas to form along with the first lumen a chamber to monitor pressure within the uterus to thereby determine if excessive pressure is being applied to the fallopian tubes of the patient. A sensor is in communication with the first lumen to measure pressure about a circumferential area of the balloon to measure pressure in the uterus to provide readings of intrauterine pressure.

A second lumen communicates with the bladder to remove fluid from the bladder. The hub includes a pressure transducer for measuring bladder pressure based on gas compression and has an elongated member insertable into the first lumen to advance gas through first lumen to expand the balloon.

Abstract: A multi-lumen catheter for monitoring intra-abdominal pressure, the catheter including an expandable outer balloon and an expandable inner balloon positioned within the outer balloon. A first lumen communicates with the inner balloon and the inner balloon and first lumen are filled with gas to form a gas filled chamber to monitor pressure within the bladder to thereby monitor pressure within an abdomen of the patient. A second lumen communicates with the bladder to remove fluid from the bladder. The catheter is configured for attachment of an external pressure transducer communicating with the gas filled chamber for measuring bladder pressure based on gas compression caused by deformation of the expanded inner balloon deformed by the expanded outer balloon.

Abstract: An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.
