Abstract: The present disclosure generally relates to wireless power transfer systems, and more specifically, relates to using a wireless power system for inductive telemetry communications. Accordingly, the present disclosure describes providing an inductive telemetry control signal to the wireless power coils associated with a transcutaneous energy transfer system to generate a telemetry communication signal. The transcutaneous energy transfer system includes a wireless power transfer transmit coil and a wireless power transfer receive coil. The telemetry communication signal may be transmitted from the wireless power transfer receive coil to the wireless power transfer transmit coil, as well as from the wireless power transfer transmit coil to the wireless power transfer receive coil for bidirectional communication.

Abstract: Described herein is an implantable medical device including a housing, a header coupled to the housing, and a receptacle connector stack disposed in the header. The receptacle connector stack includes a plurality of electrical contacts and a plurality of wiper seals. Each electrical contact of the plurality of electrical contacts is separated by a corresponding wiper seal. A first sealing element is disposed at a proximal end of the receptacle connector stack and a second sealing element is disposed at a distal end of the receptacle connector stack. The sealing elements are mounted on respective seal housings. A third sealing element is disposed adjacent to the first sealing element and further proximal of the connector stack to restrict a bounce back effect caused by one or more of the plurality of wiper seals during insertion of a lead.

Abstract: The present invention generally relates to heart treatment systems. In some aspects, methods and systems are provided for facilitating communication between implanted devices. For example, an implantable cardiac rhythm management device may be configured to communicate with an implantable blood pump. The implantable cardiac rhythm management device may deliver heart stimulation rate information in addition to information associated with any detected abnormalities in heart function. In response, the pump may be configured to adjust pumping by the pump to better accommodate a patient's particular needs.

Abstract: Circulatory support systems and related methods are disclosed in which a ventricular assist device is controlled based on cardiac activity monitored via cardiogram electrodes. A circulatory support system includes a ventricular assist device, cardiogram electrodes, and a controller. The controller processes a cardiogram signal generated via the cardiogram electrodes to determine one or more physiological parameters indicative of an activity level and/or cardiac cycle timing, determines at least one operating parameter for the ventricular assist device based on the one or more physiological parameters, and controls operation of the ventricular assist device in accordance with the at least one operating parameter.

Abstract: An oxygenator and method for oxygenating blood. The oxygenator includes a housing, an oxygenation chamber, and elongated gas permeable conduits that extend across the oxygenation chamber. The blood flow enters and contacts with exterior surfaces of the conduits and exits the oxygenator to transfer of oxygen from within the conduits to the blood flow and transfer carbon dioxide from the blood flow into the elongated gas permeable conduits. The housing includes a gas inlet and is configured to distribute a gas flow received through the gas inlet to the elongated gas permeable conduits so as to a first portion of the gas flow flows through a first set of the elongated gas permeable conduits in a first direction and a second portion of the gas flow flows through a second set of the elongated gas permeable conduits in a second direction that is opposite to the first direction.
