  • Patent number: 11612725
    Abstract: Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

  • Patent number: 11590282
    Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device involves obtaining one or more measurement values of a physiological condition in the body of a user during an initial monitoring period and determining a fasting reference value for a metric based on the one or more measurement values. After the initial monitoring period, the method continues by obtaining an updated measurement value during a fasting period, determining a current value for the metric based at least in part on the updated measurement value, and generating a notification in response to a deviation between the current value and the fasting reference value exceeding a threshold indicative of insertion site loss or other loss of effectiveness.

  • Patent number: 11559632
    Abstract: A passive safety needle shield (300) is provided. The needle shield comprises a base (302) fixed to a proximal end of a needle, and an enclosure housing (304) initially disposed at a distal end of the needle, and enclosing the end of the needle. A hinged arm (306) connects the base (302) and the enclosure housing (304). The enclosure housing (304) is slidable along the needle length, and the hinged arm (306) flexes to permit the enclosure housing (304) to move along the needle as the needle is inserted into a user, thereby hiding the needle end, and providing support to the needle to avoid bends or buckles in the needle. The hinged arm (306) is biases in the initial position so that the enclosure housing (304) returns to the end of the needle as the needle is withdrawn.
