A system for automatically injecting a substance. The system includes an injecting device, which includes an injecting cartridge, a biasing mechanism and a latch. The injecting cartridge includes a syringe having a needle and a plunger, and an injecting mechanism for moving the syringe and pushing the plunger of the syringe. The injecting cartridge includes a needle and a plunger, and an injecting mechanism for moving the syringe and pushing the plunger of the syringe. The biasing mechanism pivots the injecting cartridge from a storage position into an injecting position. The latch is moveable from a holding position for holding the biasing mechanism in the storage position to a release position for releasing the biasing mechanism. The system may further comprise sensors to measuring physical signs of a user. The system may also include controller to control the automatic injection of the substance.

The invention relates to a medical fluid drainage device for drainage of edematous tissues comprising at least one pumping element (1, 23, 33), having an inlet and an outlet, at least one outlet member (2) having at least one lumen, connected directly or indirectly to the outlet of said pumping element and connecting said pumping element to a body cavity or to a vessel or to a subcutaneous area, and at least one inlet member (3) connected to said inlet of said pumping element and providing fluidic connection between said edematous tissue and said pumping element, and characterized in that the inlet member comprises at least two inlet lumens (4, 5, 6) connected in parallel to said inlet of said pumping element, each of said lumens (4, 5, 6) contains at least one fluid access region, wherein each fluid access region (8, 9, 10) being adapted to allow simultaneous edematous fluid entry from distinct regions of said edematous tissue.

A platform and methods of use, for providing active, pre-determined, fully controlled, precise delivery of nano- or micro-particles in biological tissue. The platform comprises the following modules: (A) one or more nano- or micro-particles comprising embedded logic and various MEM components; (B) a delivery and retraction module, configured to deliver and retract the particles; (C) an external signal generator; (D) an imaging module, configured to monitor said particles; and (E) an integration module configured to receive inputs from other modules and provide output control commands to other modules. The modules are configured to interact/communicate with each other and are internally controlled, externally controlled or both.

A carrier device and methods of use, for implanting in biological tissue and releasing a medical payload in the biological tissue according to remote ultrasound trigger pulses. The carrier device includes at least one internal resonant element with a resonance frequency in the ultrasound range. When an ultrasound pulse at the resonance frequency is sent through the tissue, the resonant element vibrates at high amplitude and raises the internal pressure of the carrier and releases the payload. In some embodiments, payload release can be started, stopped, and restarted at a later time or place. Individual carrier devices can be selectively triggered by providing different resonance frequencies, and external resonant elements can provide propulsion and navigation capabilities.

A magnetically driven tattoo machine is disclosed, which has a substantially radially symmetric exterior shape and be driven by a sensor-controlled electromagnetic coil. The machine has no oscillating mechanical components, and thus reduces or eliminates vibration. The machine may include a housing mechanically isolated from a needle cartridge or subcomponents that can be disassembled and sterilized. The electromagnet may be controlled by a sensor integral with the coil, housed within the machine, or within an external power supply. The machine may be powered by internal battery or by an external power source. The machine may also be controlled wirelessly.

The present disclosure relates to vaporization systems and interchangeable elements forming such systems. In particular, a plurality of control devices may be interchangeably combined with one or more cartridges to provide an overall vaporization system that provide customizable vaporization characteristics for a consumer. The vaporization system further can include at least one external connection device for charging and/or data communication.
