An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, a pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle is completely received in the housing to a second needle position wherein the needle protrudes from the housing. The pump may be a roller.

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.

A method and a device for needleless injection of liquid into a substrate, in particular of a liquid pharmaceutical or cosmetic preparation into a biological tissue, which makes it possible in a particularly advantageous manner to reliably inject a particularly fine liquid jet into the substrate without a significant increase in the static pressure in the liquid during the injection process. According to the invention, this is achieved by first accelerating the liquid received in a liquid container together with the latter to an initial velocity before the movement of the liquid container is stopped again, while simultaneously ejecting the liquid from the liquid container through an outlet nozzle under at least partial retention of its movement. Preferably, the ejected liquid jet is set in rotation about its jet axis before it impinges on the substrate, so that the jet receives a helical movement and thus practically drills into the substrate without splashing away laterally.

A process and a nebulizer for dispensing a consecutively dose of medicament in the form of a mist, comprising: an energy source (ES), an air-conditioning volume, an air outlet fluidity connected to the air-containing volume, an air actuator adapted to release a flow of compressed air through the air outlet at such time as a predetermined ES pressure has been reached in the volume and at least two valve means in communication with the air actuator. The compressed air is released at a predetermined pressure of about 20 to about 100 psig. The valve means controls the actuation of the air actuator such that when a medication is nebulized, a mist distribution of a medication is formed having droplets size in the range of approximately 1 to approximately 7 which inhaled by a user at a set of predetermined intervals.

A method for injecting a substance through a biological body surface includes providing a needle-free transdermal transport device configured to inject the substance through the surface. The substance is injected into the biological body with the transport device while a parameter of the injection is sensed and a servo-controller is used to dynamically adjust at least one injection characteristic based on the sensed parameter. The substance is injected for (i) a first time period during which a first portion of a volume of the substance is injected at a first injection pressure, and (ii) a second time period during which a remainder of the volume of the substance is injected at a second injection pressure. A viscosity of the substance may be determined, and a pressure calculated for injecting the substance based on the viscosity. The substance may be injected with the transport device by using the calculated pressure.

A system for supplying energy to an implantable medical device when implanted in a patient's body can comprise an internal charger arranged to be implanted in the patient's body, the internal charger comprising a first coil. The system can further comprise an external charger arranged to wirelessly transmit energy to supply power to the internal charger, using a second coil. The system also comprises a wireless feedback system arranged to transmit feedback information from the internal charger to the external charger. The feedback information is based on information from at least one Radio Frequency Identification (RFID) transmitter. Hereby a user of the system can optimize the position of the external power supply in relation to the internal power supply based on the received feedback information. This in turn will result in a better and more robust energy transfer to the implanted medical device.

A cartridge assembly apparatus for an auto-injector includes a flexible container containing a liquid medicant. A needle hub is connected to the flexible container. A needle is attached to the needle hub and extends proximally from the needle hub. A frame is connected to the needle hub and includes a frame proximal end extending proximally beyond a proximal end of the needle. The needle hub and the needle are displaceable relative to the frame in a proximal direction to insert the needle into a patient.

A device for delivering a medical fluid (4) comprising a body which houses: at least one containment tank (20) of a medical fluid, a fluid injection device (24) which interfaces with said containment tank (20) and is suitable to allow controlled delivery of a fluid through a cannula (32), an extraction device (40) of the cannula (32) from a retracted or rest configuration to an extracted or infusion configuration, activation means (44) which comprise a rotor (48), rotatable about a rotation axis (X-X) in an injection rotation direction (I) and in a control rotation direction (C), opposite each other.

In some aspects, the present disclosure pertains to a hydrogel agitation and injection assembly, the assembly comprising a delivery device providing a barrel configured as a reservoir for an injectable hydrogel; and a shuttle disposed in the reservoir, where the shuttle is configured at least to translate along a longitudinal axis of the delivery device responsive to an application of a magnetic field to the shuttle, and where the shuttle includes an aperture extending entirely through the shuttle along the longitudinal axis of the delivery device.
