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, wherein the operation device comprises a first unit comprising a receiving unit for receiving wireless energy and a first gear system adapted to receive mechanical work having a first force and first velocity, and output mechanical work having a different second force and a different second velocity. The operation device further comprises a second unit comprising an electrical motor adapted to transform electrical energy to the mechanical work, and a distance element adapted to separate the first and second units such that the receiving unit, when receiving wireless energy, is not substantially affected by the second unit.

The invention relates to an apparatus for single administration of a medicinal product. The apparatus has a housing and a second component arranged for movement relative to the housing. During the administration of the medicinal product, the second component shifts from a first position relative to the housing into a second position relative to the housing. Fixed on the housing is a first magnetic element, and arranged on the moveable component is a second magnetic element. In the first position, the first magnetic element and the second magnetic element are close to one another (alternatively spatially separated from one another), and in the second position the first magnetic element and the second magnetic element are spatially separated from one another (alternatively close to one another), with the result that the magnetic field at the location of the first magnetic element is larger (alternatively smaller) when the moveable component is in the first position than when the moveable component is in the second position.

The invention also relates to a second apparatus having a magnetic field sensor for measuring the magnetic field at a predetermined position on the apparatus for single administration of a medicinal product, and for emitting a signal according to the measured strength of the magnetic field, and to a corresponding computer-implemented method.

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 filling aid. The filling aid includes a needle housing portion including at least one tab having a starting position and a filling position, and a filling needle cradle including a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position, wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position, and wherein when the at least one tab on the needle housing moves from a filling position to a starting position, the filling needle cradle slides from a filling position to a starting position.

An adaptive system for efficient and long-range wireless power delivery using magnetically coupled resonators responds to changes in a dynamic environment, and maintains high efficiency over a narrow or fixed frequency range. The system uses adaptive impedance matching to maintain high efficiency. The wireless power transfer system includes a drive inductor coupled to a high-Q transmitter coil, and a load inductor coupled to a high-Q receiver coil. The transmitter coil and receiver coil for a magnetically coupled resonator. A first matching network is (i) operably coupled to the drive inductor and configured to selectively adjust the impedance between the drive inductor and the transmitter coil, or (ii) is operably coupled to the load inductor and configured to selectively adjust the impedance between the load inductor and the receiver coil.

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.

Provided herein is a medical device centric communication system DCCS. In particular, provided herein is a communication device (e.g., for use as part of an indwelling or attached medical device) that provides secure wireless data access, storage, and quick transmission of a relevant compendium of medical device details, specific patient associated implantation images, clinical patient, and disease treatment information. The DCCS provides quick secure access to this unique compendium anytime, anywhere, regardless of patient location—to reduce unknowns, lessen liabilities, improve patient safety, reduce physician uncertainty, as well as to improve and expedite patient care.

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.

Systems, methods and devices for paired training include timing controls so that training and neural stimulation can be provided simultaneously. Paired trainings may include therapies, rehabilitation and performance enhancement training. Stimulations of nerves such as the vagus nerve that affect subcortical regions such as the nucleus basalis, locus coeruleus or amygdala induce plasticity in the brain, enhancing the effects of a variety of therapies, such as those used to treat tinnitus, stroke, traumatic brain injury, post-traumatic stress disorder, speech deficit or language deficit.
