    Abstract: The present disclosure describes various catheters that address potential recoil issues. Such catheter may contain multiple lumens that allow for the discharge of infusants a various points on the catheter distal end. Further, multiple openings may be present on the distal end of the catheter. The openings can be covered with a membrane that ruptures at a designated flow pressure. The catheter tip can contain blind holes that remain covered, and are only opened to become active when required. Such catheters can allow for multiple infusant flow exits, rather than a singular steady jet exiting the distal end of the catheter.

    Abstract: The invention is a device and method for measuring, inter alia, blood oxygenation, arterial/venous blood gas, and/or hemoglobin values in an already-inserted arterial or venous catheter in a patient. It allows the measurement of a meaningful and commonly understood metrics of blood oxygenation and gas exchange in hypo-perfused patients while avoiding the additional discomfort and risk of infection posed by inserting a standalone device with its own catheter. Analogous uses of the apparatus for other measurements is possible.

    Abstract: Hemodialysis catheter 100 with corrugated tips includes elongated body 110 having first and second distal end regions 118, 119 terminating in tips opened to lumens extending continuously along both elongated body and distal end regions. Each tip tubular wall has a corrugated configuration with at least two grooves 128, 129, including outer and inner grooves, merging into the tip edge via diverging angles, from elongated body longitudinal axis, and may be rotationally symmetric relative to the axis. In some embodiments, tip inner wall and hollow outer surfaces merge into a corrugated form having alternating grooves and ridges along distal ends of the tip, that enable the catheter to facilitate active lateral or frontal fluid traversability therethrough.

    Abstract: A pleural manometry catheter comprises two tubes and a pressure transducer. The first tube provides a first flow path from the pleural cavity to the pressure transducer. The second tube provides a second flow path from the pleural cavity such that fluid can be drained from the pleural cavity. The pressure transducer detects real-time changes in the fluid pressure of the first flow path, such that when in use, fluid is drained from the pleural cavity along the second tube, the sensor in communication with the first tube detects a concomitant drop in fluid pressure in the fluid in the first tube.

    Abstract: Disclosed is a self-expanding cannula, systems using such cannulae, and methods of their use. The cannulae may comprise single lumen cannula (SLC) configurations and double lumen cannula (DLC) configurations, and include at least a first cannula and a self-expanding wire frame attached to the first cannula. Self-expanding wire frame is automatically expandable from a compressed state (providing a reduced cannula diameter as it is moved through a patients body to the site at which it is to be deployed) to an expanded state (which increases the diameter of the cannula to the diameter intended for its normal use). The expanded wire frame provides radial support to prevent a drainage canal (whether a patients blood vessel or a portion of the system inserted into the patients blood vessel) from collapsing as fluid is drained from the patient.
