    摘要： A fluid treatment system for a percutaneous cable and methods of assembly and use are described herein. In one aspect, the fluid treatment system includes a delivery tube comprising a distal end and a proximal end. The distal end is configured to surround at least a portion of a percutaneous cable. The percutaneous cable extends from within a patient to outside the patient through tissue at an exit site. The proximal end is connectable to a fluid source. Fluid from the fluid source is configured to be delivered to the exit site through the delivery tube. The fluid treatment system includes an anchor coupleable to the percutaneous cable to secure the percutaneous cable to the tissue at the exit site.

    摘要： A method of controlling an implantable blood pump of a living patient. The method includes receiving one or more pump signals indicating at least one from the group consisting of a motor speed of the blood pump, power supplied to the blood pump, and differential pressure exerted by the blood pump. One or more medication signals is received indicating whether the patient has taken a medication. The flow rate of blood based on a combination of the one or more pump signals and the medication signals is determined. At least one from the group consisting of increasing and decreasing power is supplied to the pump in response to the determined flow rate.

    摘要： A cover for a percutaneous connector extending through the skin of a patient. The cover includes a structure having an inner side and an outer side. A first separable connector is mounted to the structure and disposed entirely within the structure, the first separable connector being configured to detachably engage and electrically connect with the percutaneous connector. A second separable connector is mounted to the structure and electrically connected to the first separable connector, the second separable connector being exposed at the outer side of the structure and being configured to detachably engage and electrically connect with an external device. The inner side of the structure defines a skin-engaging surface at least partially surrounding the first separable connector and the percutaneous connector, when the first separable connector is engaged with the percutaneous connector.

    摘要： The present disclosure provides systems and methods for controlling wireless power transfer systems. A wireless power transfer system includes a transmitter driven by a power source and a transmit controller, wherein the transmitter is configured to control delivery of wireless power, and a receiver inductively coupled to the transmitter, the receiver configured to receive the wireless power from the transmitter and deliver the received wireless power to a load. The receiver includes receiver electronics configured to determine a Thevenin equivalent impedance of the wireless power transfer system, determine a Thevenin equivalent source voltage of the wireless power transfer system, and control, based on the determined Thevenin equivalent impedance and the determined Thevenin equivalent source voltage, an ideal source voltage of the receiver to vary the amount of the wireless power transferred from the transmitter to the receiver.

    摘要： Systems and methods and devices are provided for arresting or reversing the effects of myocardial remodeling and degeneration after cardiac injury, without the potential drawbacks associated with previously existing systems and methods, by at least partially occluding flow through the superior vena cava over multiple cardiac cycles, and more preferably, by adjusting the interval or degree of occlusion responsive to a sensed level of patient activity. In some embodiments, a controller is provided that actuates a drive mechanism responsive to a sensed level of patient activity to provide at least partial occlusion of the patient's superior vena cava, while a data transfer circuit of the controller provides bi-directional transfer of physiologic data to the patient's smartphone or tablet to permit display and review of such data.

    摘要： Blood pumps for ventricular assist devices employ a hollow rotor to impel blood through the blood pump. A blood pump includes a housing having a housing inlet, a housing outlet, and a housing blood flow channel through which the housing inlet and the housing outlet are in fluid communication. A motor stator is disposed around the housing blood flow channel and operable to generate a rotating magnetic field. A hollow rotor is disposed within the housing blood flow channel and rotated via the rotating magnetic field. The hollow rotor has a rotor circumferential wall enclosing a rotor blood flow channel. The hollow rotor has at least one rotor blade extending inwardly from the rotor circumferential wall. The at least one rotor blade is configured to impel blood through the rotor blood flow channel when the hollow rotor is rotated via the rotating magnetic field.
