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 system and method for supplying energy to an implanted medical device is disclosed. The system comprises an internal charger having a first coil, an external charged arranged to wirelessly transmit energy to supply the internal charger with energy, the external charger comprising a second coil, and a wireless feedback system arranged to transmit feedback information from the internal charger to the external charger. The feedback information is based on information obtained from at least one radio frequency identification (RFID) transmitter.

Disclosed herein is a fully implantable artificial heart. The use of flat helical springs to align and reciprocate a bellows structure allows the bellows to pump blood, the multiple solenoids with floating magnetized rods and permanent magnet assemblies held by the flat helical springs provide the power. The artificial heart pumps blood with virtually no friction and no parts to wear out. The use of solenoids advantageously move blood in a gentle, controllable manner.

System for trans-dermal delivery of doses of a medicament, comprising a delivery device to be placed in dermal contact with a patient, the delivery device comprising a reservoir for holding a medicament to be delivered, a trans-dermal injection element for delivering doses of the medicament to the patient, a control unit for controlling the delivery of the medicament when activated, the system further comprising a separate hand-held drive device to be temporarily placed in proximity of the delivery device when a dose of medicament is required, the drive device comprising an activation unit for activating the control unit of the delivery device.

A device has a hollow guide shell including an injection end and a longitudinal axis. An actuator magnet is disposed in the hollow guide shell. An injection pin is coupled to the actuator magnet. A driver magnet is positioned on the device radially outward from the actuator magnet. A fluid cartridge is disposed in the injection end of the hollow guide shell, the fluid cartridge including a needle and a plunger. The driver magnet selectively exerts an injection force on the actuator magnet in a direction oriented towards the injection end of the hollow guide shell to engage the injection pin with the fluid cartridge. A liquid, gas or other agent can selectively be ejected from the cartridge by the device to inject the fluid, gas or other agent into another object.

An automatic injection device with flow regulation. The automatic injection device has an insertion needle configured to be inserted into a patient and a drug container which contains a pharmaceutical product and includes a plunger. The automatic injection device also has a fluid path which fluidly connects the drug container to the patient via an insertion device, a potential energy source, and a regulator configured to restrict release of potential energy and restrict linear movement of the plunger and pharmaceutical product into the fluid path at a proscribed pace. The regulator includes a clock escapement mechanism. The potential energy source may be a spring that surrounds the drug container and may be magnetically coupled to the plunger. The clock escapement mechanism is configured to control the spring at a regulated rate over a time interval using a gearbox and rotational-to-linear translator comprising a rack and pinion.

The regulator includes a clock escapement mechanism and a wire and pulley system including a wire coupled to at least one pulley. The potential energy source may be a spring that surrounds the drug container and may be directly coupled to the plunger and the wire such that movement of the spring and the wire is restricted over time.

An injection device assembly including a housing, a syringe, a drive mechanism and one or more sensing systems are described. The drive mechanism advances the syringe from a storage position to an injection position, and a plunger advances the syringe piston from an initial position to a final position. The status sensing system may include one or more main PCB(s) disposed in an end portion of the injection device assembly's housing. The system may determine various parameters related to an operational status of the injection device, including the location of the device's components, an amount of medication remaining in the device, a temperature of the medication, and whether or not the device is properly contacting the user's skin before injection. The system may communicate such determined parameters to an external device via a wireless communication link.
