Abstract: An evertable tube having a lumen therethrough, an inflation port for inflating the tube, and a self-closing valve at the inflation port. The tube has an inflation port for inflating the tube to grip a member, such as a probe, in the lumen. Advancement of the member, for example through a colon, will then cause eversion of the tube. The inflation port is provided in the form of an aperture in the outer wall of the tube. The valve comprises a sheath extending from the port along a wall of the tube. The sheath may be fixed to the wall of the tube. The sheath may alternatively be integrally formed with the wall of the tube. The sheath extends from the inflation port along the wall of the tube parallel to the longitudinal axis of the tube to an open end of the sheath.

Abstract: A device to aid advancement of a colonoscope through the colon of a patient comprises an elongate body defining a colonoscope lumen. The body provides a fluid tight seal to the colonoscope. The body has an anchor to releasably anchor the interior wall of the colon to the device to enable a colonoscope to be more easily advanced. The anchor may be provided by suction apertures through which a suction is applied to draw the colon into anchored engagement with the body. The anchor may be provided by a balloon and/or foam based anchoring systems may be provided.

Abstract: A device 1 to aid advancement of a colonoscope 2 through the colon 3 of a patient comprises an elongate body 4 defining a colonoscope lumen 7. The body 4 provides a fluid tight seal to the colonoscope 2. The body 4 has an anchor to releasably anchor the interior wall of a colon 3 to the device to enable a colonoscope 2 to be more easily advanced. The anchor may be provided by suction apertures 8 through which a suction is applied to draw the colon into anchored engagement with the body 4. The anchor may be provided by a balloon and/or foam based anchoring systems may be provided.

Abstract: A system for measuring and displaying the side and top profiles of an underwater pipeline as the pipeline is being laid on the sea floor by a pipe laying vessel. The profiles are determined by sequentially measuring the position of points spaced apart along the pipeline with respect to a point on the vessel. The measurements are accomplished by sequentially transmitting an acoustic signal from three, non-colinear transducers. The acoustic signals from each transmission is detected by a plurality of receivers spaced apart along the pipeline. As each receiver detects a transmission it produces an indicating signal on a pair of electrical conductors which are connected to the vessel and all of the receivers on the pipeline. The elapsed time between a transmission from a given transducer and detection of that transmission by each receiver is an indication of the distance between the transducer and each receiver.

Abstract: An elongated pipe is held in a first constant tension mechanism and then, while the tension is maintained, the pipe load is shifted to a second constant tension mechanism by automatically correlating the declining tension force of the first constant tension mechanism with the increasing tension force of the second constant tension mechanism until the pipe is completely shifted to the second constant tension mechanism.
