Methods and apparatus for wireless power transfer and communications are provided. In one embodiment, a wireless power transfer system comprises an external transmit resonator configured to transmit wireless power, an implantable receive resonator configured to receive the transmitted wireless power from the transmit resonator, and a user interface device comprising a resonant coil circuit, the resonant coil circuit being configured to receive magnetic communication signals from the transmit resonator or the receive resonator and to display information relating to the magnetic communication signals to a user of the user interface device.

The present disclosure describes intravascular oxygenation systems and methods with one or more of improved oxygen diffusion flux, improved resistance to bubble formation on the surface of non-porous hollow fibers, and reduced size. The systems and methods include a pneumatic inlet coupled to a pneumatic source that provides a gas containing oxygen at a high pressure. A plurality of hollow fiber membranes (HFM) are in pneumatic communication with the pneumatic inlet to receive the gas containing oxygen and with an outlet to exhaust a partially deoxygenated gas. An electronic controller drives the motor to oscillate the plurality of HFMs to cause a diffusive flux of the gas containing oxygen from the plurality of HFMs into a region of interest of a subject. The electronic controller may drive the motor according to an oscillation pattern, which may include a macro-oscillation with superimposed micro-oscillations.

A system for regulating blood flow through a blood vessel of a heart includes a valve and a controller. The valve includes an outer frame and two or more leaflets and is sized for placement at least partially within the blood vessel. The two or more leaflets are sized to overlap or contact each other in an expanded state. The controller is disposed outside the heart and transmits signals to the valve.

The disclosure relates to a device for transcutaneously transmitting energy into a human body. The device may include an extracorporeally arranged transmission device that includes an induction charging coil and a sensor. Upon receiving an electrical current, the induction charging coil may provide a magnetic field to inductively transmit energy to an induction coil arranged intracorporeally, transcutaneously powering a medical device, such as a mechanical circulatory support system within in the body. The sensor may provide a position signal representing a relative position between the induction charging coil and the induction coil. In turn the position signal may be used to position the extracorporeal induction coil so that energy it is concentrically aligned with the intracorporeal induction coil and energy can be efficiently transferred to the medical device.

A device for controlling the functioning of a cardiac prosthesis, the device for controlling includes a control path, the control path having a control system designed and arranged to monitor and regulate the electrical supply of a cardiac prosthesis; a first insulating system designed and arranged to electrically insulate the cardiac prosthesis from the electrical supply; and a controller designed and arranged to monitor and regulate the electrical supply.

Methods and devices for tying management of an implantable medical device to the activities of a primary care physician are described, including access control, simplified parameter optimization, support for tuning a device in response to the effects of other treatments in parallel, and support for helping a primary physician and a patient work together to tune device configuration to the activity and performance needs of the patient. In some embodiments, a medical device is self-configuring in a device parameter domain, based on inputs provided in a patient performance domain. The self-configuring of the medical device is based, for example, on an automatically applied transformation of inputs derived from patient performance domain observations into changes in the configuration of the medical device which affect technical parameters of its operation.

Described are systems and methods for administration of nitric oxide (NO) with use of left ventricular assists devices (LVADs), as well as systems and methods for monitoring the NO delivery devices and/or the LVAD.

A dual lumen coaxial cannula assembly including a first infusion tube having a proximal end, a distal end, and a sidewall extending circumferentially therebetween, as well as a second drainage tube co-axially aligned with the first infusion tube, the second drainage tube having a proximal end, a distal end, and a sidewall extending circumferentially therebetween. The assembly also includes a connector assembly, which has an inlet portion through which a portion of the first infusion tube is configured to extend and an outlet portion through which a portion of the second drainage tube is configured to extend. The connector assembly is configured to enable selective axial displacement of the first infusion tube through the second drainage tube.
