  • Patent number: 9199025
    Abstract: A filter member used in an oxygenator is constructed to provide improved contact with a hollow fiber membrane bundle and to capture bubbles contained in blood. The filter member possesses elasticity at least in the circumferential direction to allow the inner circumference of the filter member to be increased from a natural non-expanded state prior to placement on the hollow fiber membrane bundle to an expanded state in which the inner circumference of the filter member is increased when placed on the hollow fiber membrane bundle. The filter member is constructed to satisfy the condition 0.5?L2/L1<1, wherein L1 represents the outer circumference of the hollow fiber membrane bundle and L2 represents the inner circumference of the filter member in the natural non-expanded state.

  • Patent number: 9199060
    Abstract: A non-bladder invasive urethral catheter system with a urethral balloon element for relieving urinary incontinence. The catheter system is more convenient and less intrusive compared to bladder catheters and permits the catheter to remain in the urethra during urination. The catheter system blocks urine flow and leakage in the urethra by means of the urethral balloon element while inserted within the urethra. Two or more different urethral catheters are utilized that are differentiated by the positioning of a urethral balloon element on the elongated body of the urethral catheter. Through the placement of the urethral balloon element in different positions in the urethra with the different catheters, the trauma produced by a urethral balloon element to a particular area of the urethra is reduced or eliminated, allowing long term use of a catheter in the urethra.

  • Patent number: 9186450
    Abstract: A method and apparatus for priming an extracorporeal blood circuit, in which the patient end of an arterial line (79) is connected to a first discharge port (61), and the patient end of a venous line (87) is connected to a second discharge port (62). The two discharge ports are connected to a used dialysate line which connects a dialyzer (33) to a drain. The arterial and venous lines are filled with a priming fluid, while the air contained in the arterial and venous lines is evacuated partly through the first discharge port and partly through the second discharge port. Two check valves (65, 66) prevent flow from the used dialysate line towards the two discharge ports. The invention reduces the risk of errors on the part of an operator readying the priming configuration, as well as the risk of contamination of the extracorporeal circuit during the priming phase.

  • Patent number: 9180239
    Abstract: A device and method for oxygenating blood is disclosed herein. The device includes a plurality of passive mixing elements that causes a fluid to mix as it flows through the device. The passive mixing elements continually expose new red blood cells to the portion of the flow channel where oxygenation can occur. Accordingly, in some implementations, the device and method uses less blood to prime the device and allows for the oxygenation of blood with a substantial shorter flow channel when compared to conventional oxygenation methods and devices.

  • Patent number: 9173734
    Abstract: An intragastric anchor implant device with an elongate member having proximal and distal ends with atraumatic features disposed thereon is described herein. The atraumatic features inhibit damage to the tissues of the stomach and the gastrointestinal tract and help anchor the device. The elongate member may be substantially rigid to resist bending and engage a tissue of the stomach or gastrointestinal tract to prevent passage therethrough and may include one or more bends to conform to the shape of the tract. The anchor implant device may be coupled with a therapeutic device, such as an intestinal bypass sleeve with a sliding seal, such as an expandable structure, that secures the sleeve to direct a flow of food particles from the stomach therethrough, for use in treating various disorders, including obesity and diabetes. Methods of deploying the anchor implant devices are also disclosed.

  • Patent number: 9144646
    Abstract: In some aspects, a vial spiking device includes a base, a spike extending from the base, and a side wall extending from the base and substantially surrounding the spike. The base and the side wall partially define a recess to receive a portion of a vial. Resilient fingers extend inwardly from the side wall into the recess. The fingers are spaced circumferentially around the side wall and are configured so that as the vial is inserted into the recess, the fingers deflect toward the side wall and allow the portion of the vial to move beyond the fingers. The fingers rebound into the recess after the portion of the vial has moved beyond the fingers. The side wall forces the portion of the vial away from the base and into contact with the fingers after the fingers have rebounded into the recess.

  • Patent number: 9138568
    Abstract: An apparatus capable of generating flow in cerebrospinal fluid (CSF) shunt systems by vibrating the shunt, tubing or shunt valve dome, or applying cyclical pressure to the various parts of the shunt system. A method of generating flow and method of using the apparatus in shunt patency assessment, for example, hydraulic resistance assessment, is also disclosed. The apparatus allows, in conjunction with a thermal dilution method or radionuclide method, a quick CSF shunt patency assessment based upon CSF shunt resistance and not upon CSF flow or intracranial pressure (ICP) separately. This provides a more objective measure of shunt obstruction compared to other methods. Furthermore, the apparatus can be used to enhance flow in shunts, identify partial occlusion before symptoms occur, differentiate between patent, partially-occluded and occluded shunts. The apparatus can be used to generate flow in shunts if there is a need to lower ICP or move drugs administered via an injection chamber or a shunt dome.

  • Patent number: 9138522
    Abstract: Blood or other fluids can be caused to interact with a gas by providing a plurality of fluid flow channels that are surrounded by nanotubes, each of the channels having an inflow end and an outflow end, wherein each of the channels is wide enough for the blood to flow through, and wherein the nanotubes are spaced close enough to each other to retain the fluid within the channels when the blood is flowing through the channels. The fluid is then passed through the through the channels while a gas is passed through the spaces between the nanotubes outside the fluid flow channels. This permits the gas to interact with the fluid in the channels.

  • Patent number: 9119578
    Abstract: In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum.
