Abstract: A fetal probe has an inflatable balloon (114) positioned so as on inflation to hinge open a leaf (110) carrying an ECG electrode (130) or other sensor. Wedging action ensures that the probe is reliably and reproducibly positioned in the uterus. The balloon is interconnected with a pressure monitor so that intrauterine activity can be mesured.

Abstract: The present invention provides in one aspect an apparatus for in vivo monitoring of physiological pressures, comprising a pressure sensor (2) having a pressure sensing interface, yielding a signal indicative of the pressure differential across said interface; means (3, 13) for pressurising or depressurising the sensor interior in response to a change in the signal from said sensor; pressure measuring means (5) for measuring the pressure supplied by the pressurising means yielding a signal indicative of the pressure in the sensor interior; and means (17) for registering a total pressure as the sum of the signals from said sensor and said pressure measuring means respectively. In another aspect it provides a method of localising a damaged intervertebral disk, comprising the steps of measuring the pressure in a first disk suspected to be damaged, measuring the pressure in the disks surrounding said suspected disk, preferably simultaneously with the measurements in the first disk, registering whether there is a difference in pressure between the disks, and selecting the disk with a differing pressure to be the damaged disk.

Abstract: A portable instrument for measuring bodily movement in the lumbar spinal area includes an articulated enclosure having a first housing (10) fastened to the body of a subject by means of a first rigid plate (22). A hinged second housing (14) movably connected to a second plate (25). Both the first and second plates (22, 25) are adapted to be fixed behind the body of a subject with the second plated at a location vertically above the first plate. Transducers or sensors (19) within the housings (10, 14) are used to measure hinged motion between the two housings (10, 14) as well as relative transverse bending movement and torsional movement between the two plates. These relative movements produce electrical signals that directly correspond to the amount of flexion/extension, lateral bending and axial rotation occurring at the lumbar spine of a monitored subject.

Abstract: A pressure sensing lead (12), wherein a hollow needle (16) extending from the distal end of the lead is coupled to a pressure transducer (18, 26). The hollow needle may be coiled and adapted to be screwed into human tissue, for example through the ventricular septum (36) from the right ventricle into the left ventricle of a patient's heart, or through the wall of the heart into the pericardial sac. Alternatively, the hollow needle (462) may be straight and a separate coiled needle (416) mounted around the straight needle may be provided to affix the lead to body tissue. Pressure gradients are communicated from the tip of the hollow needle to its base and applied to the pressure sensor, allowing, for example, left ventricular pressure measurements to be taken from the right ventricle or pericardial sac pressure measurements to be taken from within the heart without the necessity of the pressure sensor itself passing through the heart wall.

Abstract: A balloon (24, 358) is inserted by means of a catheter (19, 350) into the esophagus (26) and positioned adjacent the left atrium (28). As the balloon is gradually inflated, a tracing (108) on a steady baseline is obtained representing balloon pressure oscillations effected by left atrial pressure. The mean balloon pressure (110) indicative of approximate mean left atrial pressure is measured at the time when the amplitude of the balloon pressure oscillations effected by the left atrial pressure is at a peak. The catheter includes a naso-gastric tube (352) and is passed centrally of the balloon (358) so that contact between the balloon and the esophageal wall is not obstructed for greater reliability of mean left atrial pressure determinations. The catheter may also include an esophageal stethoscope (360) and/or an esophageal temperature sensor (362).

Abstract: An apparatus (10) for monitoring intracompartmental pressures, such as intrauterine pressure, is disclosed. The apparatus (10) comprises a catheter (12) having a first chamber (16) formed in the interior of the catheter tip which is in fluid communication with the amniotic fluids contained in the uterus. A second chamber is defined by a lumen (30) of the catheter (12) and is filled with air. The lumen (30) extends the length of the catheter (12) from the first chamber (16) at the tip of the catheter (12) to a diaphragm of a pressure transducer (62) located at the end of the catheter (12). Thus, an air column is formed in the second chamber defined by the lumen (30). The relative volumetric cubic capacity of the first and second chambers (16, 30) is such that, under maximum pressures which are within expected ranges, the trapped air column prevents any liquid fluids from entering the second chamber (30). Also provided is a valve (50) which in a first or ''zero'' position causes both sides of the pressure transducer diaphragm to be placed at atmospheric pressure. In a second or ''monitoring'' position the valve (50) places at one side of the diaphragm in communication with the intrauterine pressures transmitted through the lumen and a side of the diaphragm is vented to atmosphere. A second or infusion lumen (28) may also be provided in the catheter (12) to allow for infusion of fluids into and/or withdrawal of fluid samples from the uterus.

Abstract: In order to measure the pressure inside the human body or the body of an animal, the pressure is transmitted to a pressure transducer (7) by means of a balloon (1) only partly filled with a gaseous medium, which is applied to a double or multi-luminar catheter(2). The partial filling required for reliable pressure transmission is achieved by one or several piston-pumps (6, 12) or a combination of one or several piston-pumps with one or several valves (8, 9).
