  • Patent number: 10772672
    Abstract: A device and method for creating an arteriovenous (AV) fistula includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal diagonal end surface. A heating assembly, including an energized heating element, is disposed one of the distal diagonal end surface and the proximal diagonal end surface. A passive heating assembly is disposed on the mating diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface are adapted to contact opposing sides of a tissue portion to create a fistula. The angle of the proximal diagonal end surface matches the angle of the distal diagonal end surface, so that the two surfaces match one another during deployment.

  • Patent number: 10537281
    Abstract: Assessing decongestive therapy delivered to a heart failure patient involves use of an implantable sensor configured to sense a physiologic parameter indicative of the patient's diuresis status and a processor coupled to the implantable sensor. The sensor may comprise a thoracic fluid sensor, a heart sounds sensor, a cardiac chamber or arterial pressure sensor, a respiration sensor, or a blood chemistry sensor, for example. The processor is configured to determine if a target level of patient diuresis has been achieved based on a relationship between the sensed physiologic parameter and a threshold developed for the patient, and to produce an output in response to determining that the target level of patient diuresis has been achieved. The processor may be disposed in an implantable housing, in a patient-external housing, or in a network server system.
