  • Patent number: 10406322
    Abstract: A catheter assembly includes a protective tip defining an interior chamber between its proximal and distal ends. A protective lubricious sleeve is positioned within the interior chamber. A catheter of the assembly is configured to be advanced proximally into and through the interior chamber to position at least a portion of the catheter within the protective sleeve, with the protective sleeve being retained upon the catheter as at least a proximal portion of the catheter exits the proximal end of the protective tip and is advanced through a body lumen. A second sleeve may be associated with the protective tip and configured to extend distally from the protective tip to remain outside of the body lumen during use and receive a more distal portion of the catheter.

    Abstract: Technologies are generally described for detecting the presence of anastomotic leakage in the abdominal cavity through a dual action catheter placed in the vicinity of a surgery site. A portion of the dual action catheter may be affixed around the surgery site, for example, coiled around the surgery site on the intestine. Through openings on the catheter near the surgery site, a neutral fluid such as saline solution may be injected and extracted through the same openings resulting in retrieval of fluids in the same are. By testing the extracted fluids, chemical and biochemical activity within the abdominal cavity may be determined in order to gauge the start of any anastomotic leakage.

    Abstract: A method is provided to collect liquid, such as pancreatic juice water, and saline, from a body cavity of a subject. In the method, a tool is inserted through the body cavity to reach a target site in the body cavity. A body position of the subject is adjusted such that the wall surface of the body cavity including the target site intersects with a direction of gravitational force and the liquid present in the body cavity gathers on the wall surface intersecting with the direction of gravitational force. A recess is formed to be concaved on the wall surface in the direction of the gravitational force by making the tool press the wall surface of the body cavity. Therefore, the liquid present or discharged in the body cavity is accumulated in the recess. The liquid accumulated in the recess is taken out of the body of the subject.

  • Patent number: 8337411
    Abstract: Described herein are devices, systems, kits and methods for measuring intra-abdominal pressure (IAP) from a patient catheterized with a urinary catheter system. Devices may include a bypass lumen configured to connect to a pressure transducer, a sampling port connector connected to the bypass lumen, a drain tube housing configured to at least partially enclose a portion of the drain tube of a urinary catheter system, and a clamp mechanism. The sampling port connector may be configured for removable attachment to the sampling port of the urinary catheter system to form a fluid connection between the urinary catheter system and the bypass lumen of the IAP device. The clamp mechanism may be configured to controllably occlude the lumen of the urinary catheter system drain tube.

  • Publication number: 20120323144
    Abstract: A drainage and/or collection system (1) for biological fluids includes at least one conduit (40) for transporting a biological fluid (F) from a catheter (10) to a collection device (50) and a gas pressure source (70) configured to feed a gas (G) into the at least one conduit (40) between the catheter (10) and the collection device (50). The gas (G) causes the biological fluid (F) arranged in the at least one conduit (40) to drain into the collection device (50). A method includes inserting a catheter (10), draining a fluid (F) into a collection device (50) via a conduit (40), and introducing gas (G) into the conduit (40) so as to force fluid (F) remaining in the conduit (40) into the collection device (50).

  • Patent number: 8308741
    Abstract: Embodiments disclosed herein are directed to systems and methods for automatically inserting a needle into an insertion-target region of a living subject in response to a machine-vision system locating the insertion-target region. In an embodiment, a needle insertion system includes a moveable needle configured to be inserted into a living subject, a machine-vision system configured to locate an insertion-target region of the living subject, control electrical circuitry, and an actuator coupled to the control electrical circuitry. The control electrical circuitry may be coupled to the machine-vision system to receive location information therefrom about the insertion-target region, and configured to output needle targeting instructions. The actuator may be coupled to the control electrical circuitry to receive the needle targeting instructions therefrom and coupled to the moveable needle.

  • Publication number: 20110313317
    Abstract: Methods and systems for determining the concentration of one or more analytes from a sample such as blood or plasma are described. The systems described herein can be configured to withdraw a sample from a source of fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample. The analyte monitoring system can be connected to the fluid source via a connector that is configured to improve fluid flow and reduce blood clotting risk. These goals can be accomplished, for example, by employing coatings in or on a connector, positioning a resilient substance at or near the junction, by reducing dead space volume, by using resiliency to improve fit, by extending a portion of one connector to better mate with a portion of another connector, etc.
