A ventricular assist device incorporating a rotary pump, such as a rotary impeller pump is implantable in fluid communication with a ventricle and an artery to assist blood flow from the ventricle to the artery. The device includes a pump drive circuit supplying power to the pump, one or more sensors for sensing one or more electrophysiological signals such as electrogram signals in and a signal processing circuit connected to the sensors and the pump drive circuit. The signal processing circuit is operative to detect the sensor signals and control power supplied to the pump from the pump drive circuit so that the pump runs in a pulsatile mode, with a varying speed synchronized with the cardiac cycle. When an arrhythmia is detected, the pump drive circuit may also run the pump in an atrial arrhythmia mode or a ventricular arrhythmia mode different from the normal pulsatile mode.

An access port system, comprising an implantable access port, the access port including an access port body, an access port needle and a fluid flow passage provided within the body and the needle; wherein the needle is fully containable within the body, and the needle is exposable outside the body; wherein the needle is arranged within the body to penetrate outwardly of the subject from within the subject when the access port is implanted in the subject; wherein, when the needle is exposed outside the body, the fluid flow passage is open to a flow of a fluid within the access port in at least a direction entering the access port through the needle and thereafter exiting the access port from the body; and wherein the assess port includes at least one sensor configured to detect the fluid within the fluid flow passage.

An externally programmable shunt valve assembly that includes a magnetic rotor that is operable in response to an externally applied magnetic field and configured to increase or decrease the working pressure of the shunt valve assembly in finite increments.

An implantable medical pump system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, including an implantable medical pump having an medicament reservoir fluidly couple to an access port via a conduit including an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve between a closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.

An apparatus for guiding cannulation with a dialysis needle of an arteriovenous dialysis access graft subcutaneously implanted in a body of a subject. The guiding apparatus comprises an elongated body member comprising a base portion terminating in longitudinal edges, a distance between the longitudinal edges of the base portion being substantially equal to a lateral dimension of the aces graft, and an elongated tubular sleeve defining an pocket having a longitudinal dimension and a lateral dimension configured to receive the body member. The body member is adapted to be received in the pocket of the sleeve for securing adjacent the subcutaneous access graft such that the inner surface of the base portion is aligned with a cannulation point of the graft for guiding location of a needle insertion.

A system for omni-orientational wireless energy transfer is described. A transmitter unit has a transmitter resonator with a coil that is configured to be coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. At least one of the resonators is a non-planar resonator that spans a non-degenerate two-dimensional surface having at least one concave portion.

Systems, apparatuses, and methods are disclosed for optimizing management of one or more implanted artificial heart pumps. An example method includes wirelessly retrieving, via one or more portable diagnostic devices, data regarding the one or more implanted artificial heart pumps. The example method further includes analyzing, by a server device, performance characteristics of the one or more implanted artificial heart pumps based on the retrieved data. The example method further includes causing rendering of the performance characteristics. Corresponding apparatuses and computer program products are contemplated.

An operable implant adapted to be implanted in the body of a patient. The operable implant comprising an operation device and a body engaging portion, the operation device comprises an electrical motor comprising a static part comprising a plurality of coils and a movable part comprising a plurality of magnets, such that sequential energizing of said coils magnetically propels the magnets and thus propels the movable part. The operation device further comprises an enclosure adapted to hermetically enclose the coils of the static part, such that a seal is created between the static part and the propelled moving part with the included magnets, such that the coils of the static part are sealed from the bodily fluids, when implanted.

An infusion system for infusing a medication in a patient, comprising a medication dose dispensing device and a control device for controlling the dispensing device. The infusion system can be configured in a non-operating configuration, in which the dispensing device and the control device are spaced apart from each other, and in an operating configuration, in which the dispensing device and the control device are temporarily proximity-coupled. The actuating rotor of the control device and the actuated rotor of the dispensing device have a common rotation axes, and the system can compensate or block the rotation of the control device with respect to the dispensing device.

A method of using an electronic toolset for locating, reading, adjusting and confirming adjustment of an implantable bodily fluid drainage system without requiring recalibration following adjustment from a current valve setting to a new valve setting using an electronic toolset including an adjustment tool having a magnetic element and an indicator tool including a sensor array. The need to remove the electronic toolset from the patient to recalibrate or zero the sensor array prior to confirming the new valve setting is eliminated. This is realized by disposing a ferromagnetic system component of the indicator tool in a magnet shield cage made of a metallic alloy to prevent magnetic fields produced by a magnetic element in the adjustment tool during the adjusting step from influencing the sensor array.
