  • Patent number: 10960127
    Abstract: An apparatus for measuring recirculation using thermodilution during extracorporeal blood treatment including a temperature varying unit arranged to cyclically heat and/or cool blood in a venous tube segment of the blood tube system for a quasi-continuous recirculation measurement; and a detecting device configured to measure a variation of a physical parameter resulting from the heating and/or cooling. The detecting device is arranged to detect, in a case free from recirculation, a first physical parameter and to detect, in a case afflicted with recirculation, a physical parameter varied by the cooling and/or heating of the blood by the temperature varying unit as a second physical parameter in the blood tube system. A method for measuring recirculation carries out appropriate steps.

  • Patent number: 10874551
    Abstract: A method and apparatus for performing a surgical procedure is provided. The surgical procedure may be a phacoemulsification procedure but other procedures may employ the techniques disclosed. The design includes sensing, within the surgical site, for a material change in fluid flow relative to a predetermined threshold. Upon sensing the fluid flow materially differs from the predetermined threshold, the design temporarily increases aspiration vacuum pressure to the surgical site above a predetermined upper threshold toward a maximum vacuum level. The design applies electrically generated disruptive energy, including but not limited to laser and/or relatively low power ultrasonic energy, to the surgical site from a first point in time measured from when aspiration vacuum pressure is above the predetermined upper threshold to a second point in time where pressure falls below a predetermined lower threshold.

  • Patent number: 10806891
    Abstract: A method for infusing a liquid into a patient's vasculature in accordance with an infusion protocol is disclosed. For this method, an infusion catheter having a multi-lumen infusion unit that is mounted adjacent the catheter's distal end is positioned in an artery within a predetermined distance from an intended target tissue surface. An inflation balloon is then deployed to at least partially occlude the artery and a force is exerted on the liquid to establish a flow rate for the liquid in the catheter. Specifically, the force is exerted to infuse the liquid from the catheter through the infusion unit and into the vasculature with a homogeneous distribution of the liquid to cover the intended surface of the target tissue. The flow rate can be established in accordance with an infusion protocol that is characterized by time and liquid volume parameters based on viscosity and pressure values in the liquid.

  • Patent number: 10398811
    Abstract: Medical wound irrigation systems are described that may be used in environments such as hospitals and first aid stations, and for military applications, e.g., for medics and along transport routes for the wounded. The irrigation systems can provide continuous variable pressure for irrigating a wound. For example, in some embodiments, a medical irrigation system can be used to provide a steady pressure level while irrigating about one liter of solution in less than about one minute, e.g., to assist during wound irrigation and debridement. The medical irrigation system may include an air-powered irrigation device, which pressurizes an irrigation solution, such as a cleansing fluid, to create an ejection force. In some embodiments, the medical irrigation system can include a replaceable bottle cap with an inlet for connecting to a source of pressurized fluid (e.g., pressurized gas, such as pressurized air) and an outlet for the irrigation solution/cleansing fluid.

  • Patent number: 10363403
    Abstract: A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distal ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

  • Patent number: 10328186
    Abstract: A device for the drainage of a pleural effusion through an operatively engaged chest tube in the chest wall. The device employs a check valve situated between a vacuum source communicating with the chest tube to prevent reversal of the fluid flow out of the patient's body and possible contamination. A valve mounted on a vacuum bottle provides user control of communication of negative pressure from the vacuum bottle to the chest tube. Opening the valve on the bottle communicates negative pressure to the chest tube relative to the pressure in the tube thereby initiating a fluid flow out of the tube and the patient. Once the valve on the bottle is closed, fluid flow ceases and the check valve prevents reversal of the flow.

  • Patent number: 10285708
    Abstract: Various systems and methods are provided for reducing pressure at an outflow of a duct such as the thoracic duct or the lymphatic duct. In one embodiment, an indwelling catheter can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter can include first and second restrictors each configured to at least partially occlude the vein within which the catheter is implanted and thus to restrict fluid flow within the vein when the restrictors are activated. The restrictors can each be configured to move between an activated configuration, in which the restrictor occludes the vein, and a relaxed configuration, in which the restrictor does not occlude the vein. The catheter can include a pump, such as an axial motor pump, configured to pump fluid through the catheter.

  • Patent number: 10273442
    Abstract: A device and methodology for concomitant ejection and suction of a perfusate (CESOP) within a region of interest without spillover of the perfusate to a juxtaposed anatomical region. An inflow line, connected to a perfusate cistern, is coupled to an outflow line, connected to outflow control mechanisms, via an elongate rigid support. Perfusate can flow through the inflow line to the region of interest, and nearly simultaneously, the outflow line can suction the perfusate out of the region of interest. The amount of time that the perfusate remains in the region of interest is sufficient to take effect in the region of interest. The rigid support helps control the inflow and outflow lines. A micromanipulator can also be used to control the lines and application tip thereof. Either or both lines may also have adjustable flow rates therethrough and may include stoppers/regulators.

  • Patent number: 10207086
    Abstract: Systems, methods, and devices are provided for the treatment of edema. In one aspect a method for implanting an indwelling catheter within a vein of a patient is provided. The catheter can extend from a position upstream of at least one outflow port of a duct of the lymph system to a terminal position downstream of the at least one outflow port. In use, a first restriction can be created within the vein proximal to a distal region of the catheter. The first restriction can define a localized low pressure zone distal of the restriction and within a portion of the vein housing the catheter. The low pressure zone can be adjacent to the at least one outflow port to enable fluid to pass from the at least one lymph duct outflow port into the vein.

  • Patent number: 10159780
    Abstract: This system for in-body-cavity liquid perfusion of a circulating type which circulates a liquid such as an isotonic solution perfused within the body cavity, suppresses an excessive increase in internal pressure that would lead to breakage of a hollow fiber membrane module. A drain valve is connected to a drain port of the hollow fiber membrane module. A pressure sensor measures the internal pressure of the hollow fiber membrane module. A control unit opens the drain valve on the basis of the internal pressure of the hollow fiber membrane module measured by the pressure sensor, draining foreign matter from the hollow fiber membrane.
