Abstract: A low profile parenchymal bolt having a cap, a body, and a base with a threaded screw located through the cap that engages a threaded shaft anchored to the base. Rotating the screw into the threaded shaft causes the base to move towards the cap compressing the body and causing its outer diameter to increase into contact with an opening in the skull of a patient to form a fluid-tight seal. An off-center lumen is formed through the cap, body, and base, and moving the base toward the cap also causes the body to decrease the size of the lumen thus clamping an instrument mounted through the lumen in place in the bolt and therefore, the skull of the patient.

Abstract: A system for monitoring the advancement of a needle (1) detects the puncture of the peritoneum and of the entrance into the abdominal cavity at the beginning of a laparoscopic operation. The need of such a system is mostly recognized in re-operation cases and in operations on overweight patients with lots of fat tissue. A sensor (3) capable of measuring vibration during punctures is placed and coupled on any location on the needle (1) and is protected against thermal and/or mechanical interactions. Initially the puncture information is relayed to the user of the system via a visual display such as an oscilloscope (6). A computer (8) with communication capabilities (I/O cards) or other means of processing could be added to the system. With the use of a computer (8) the signal can be processed and transformed to other means of display: colour leds, graphs, an audio indicator (change of tone, volume etc...) or a haptic indicator.

Abstract: Devices and methods for measuring the weakness of body lumens, and in particular, urethral sphincters and similar valves are disclosed. In one embodiment of the invention, a catheter (12) with a hollow fluted distal end (14) can be inserted into a lumen (44). The hollow fluted distal end (14) of the catheter (12) is then expanded into an enlarged configuration (30). The measurement of resistance to withdrawal of the catheter (12) in the enlarged configuration (30) provides an indication of weakness of the lumen (44). In one aspect of the invention, the catheter (12) is inserted into a bladder via the urethral sphincter (42) and the weakness of the urethral sphincter (42) is measured. In another aspect of the invention, a device for measuring weakness of a body lumen, such as a urethral sphincter (42) and similar valves, can consist of a catheter (12) with a hollow fluted distal end (14) having of an array of wings (16) and an expanding means (24) for radially expanding the wings (16) into an enlarged configuration (30). Subsequent withdrawal of the catheter (12) in the enlarged configuration (30) encounter resistances which can be measured as an indication of the weakness of the body lumen, such as a urethral sphincter (42) and similar valves. In still another aspect of the invention, a system for measuring weakness of a body lumen can consist of a catheter (12), a means (24) for expanding a hollow fluted distal end (14) of the catheter (12) from a first configuration into a second enlarged configuration (30) and means for measuring resistance to withdrawal of the catheter in the enlarged configuration (30) as an indicator of weakness of the body lumen, such as the urethral sphincter (42) and similar valves.

Abstract: A hollow screw (1) has a section (3) at the patient end radially sprung by longitudinal slots (6) which has outwardly directed supporting surfaces (4) perpendicular to the longitudinal direction. The hollow screw (1) is transfixed by an expanding sleeve (10) which can be inserted or screwed into the hollow screw (1) and thus expands the radially sprung section (3) with the supporting surfaces (4). Thus the supporting surfaces (4) bear on the inner surface of the skull in the manner of an expanding anchor. The skull bones are finally clamped between the supporting surfaces (4) and the locknut (20) by means of said locknut (20). On the instrument side, the expanding sleeve (10) has a medicinal coupling (12). The cerebral pressure measuring probe screw of the invention largely excludes the possibility of incorrect manipulations and ensures correct positioning regardless of the thickness of the skull.

Abstract: A non-invasive apparatus for obtaining a quantitative determination of mean left atrial pressure comprises a balloon (24) to be inserted by means of a catheter (20) into the esophagus (26) and positioned adjacent the left atrium. As the balloon is gradually inflated, a tracing of mean balloon pressure is obtained. In addition, a tracing of balloon pressure on a steady baseline and with low frequency oscillations due to respiration filtered out is obtained whereby the tracing represents balloon pressure oscillations effected by left atrial pressure. In accordance with the oscillometric principle the mean balloon pressure is measured at the time when the amplitude of the balloon pressure oscillations effected by the left atrial pressure is at a peak. This mean balloon pressure is indicative of approximate mean left atrial pressure. Mean left atrial transmural pressure may be determined by subtracting therefrom the mean esophageal pressure as measured at a position in the esophagus where it is unaffected by the heart.

Abstract: The device described consists of three sub-assemblies: a detector (S1), an amplifier (S2), and a recorder (S3) the detector (S1) measures pressures ranging from 0 to 7 600 mm/Hg, and withstands permanent overloads of 11 400 mm/Hg without any change in its characteristics. A specialized amplifier (S2) shapes the signal emitted by (S1). It has three measurement ranges: 1 900; 3 800 and 7 600 mm/Hg, and an automatic display of the values at T0/s and T60/s. A recorder connected to (S2), provides the track of the pressure signal. It has three recording speeds: 2.5, 5 and 10 mm/s. (S2) and (S3) are located in the same casing and form a single unit. The device according to the invention is particularly well-suited for measuring the pressure of a liquid injected into a compliant medium, such as a liquid compartment of the articular type or an intervertebral disc of humans or animals.
