The device comprises two pyramids 1, 2 in the form of hollow vessels sharing a common apex 4 and interconnected by a tubular channel 11. A base 8 of an upper pyramid 2 is provided with a removable lid 9. An antenna represents an EH-antenna 3 having oscillators in the form of the pyramids 1, 2, the parameters of which are consistent with the golden section, satisfy an even number from the Fibonacci series (F2=1.62), and are specified by the formula: α=2h.sup.2/s, where a is the side length of the bases, h is the height of each pyramid, and s is the apothem. A toroidal permanent magnet 14 is assembled on the outer surface of the tubular channel 11, and an audio/video device 19 along with a means for monitoring the physical parameters of the liquid medium within the volume of the pyramids 1 and 2 are mounted in the leak-proof compartment of cavity 13 of the lower pyramid 1. Lid 9 of base 8 of the upper pyramid 2 has a photovoltaic power source 10 disposed thereon for providing operation of the audio/video device 19 and means 18 for monitoring the physical parameters of the liquid medium within the volume of the pyramids 1 and 2.

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 fluid pump or rotary cutter having at least one first element (9′″, 10′″) which can be brought from a transport slate into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating stale which is as comfortable as possible and in so doing leaving a freedom in the design of the corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

A system of medical devices includes a first medical device, a second medical device, an RLC circuit, a processor, and an output device. The first medical device includes an elongate member having a lumen. The second medical device includes a needle advanceable through the lumen. The RLC circuit includes an excitation voltage source, a resistor, a capacitor, an inductor, and an output voltage sensor. The inductor includes a coil that is supported by the first medical device and wound around the lumen. As the needle is advanced through the lumen, an output voltage of the RLC circuit is an indicator of a longitudinal position of the needle with respect to the elongate member. The voltage sensor is configured to sense the output voltage, and the processor and output device are configured to generate an output that is an indicator of the longitudinal position of the needle.

Provided is a medical device with portions configured for fitting and being retained simultaneously into two cavities on opposite sides of the body of a subject, for example the eustachian tubes or the fallopian tubes. The device may include an elongated member with a central segment and first and second peripheral segments extending therefrom. These segments differ in their intended function and eventual in situ positioning: the two peripheral segments intended for insertion and positioning within the two cavities and exerting their function within the cavities. The central segment serves as a link between two peripheral segments and may also be used for some other functions by its position. The elongated member may have elastic properties.

A medical device such as a needle subassembly is disclosed including a cover over a magnetized portion of a tissue-penetrating medical device having a shielding material associated with the cover that prevents the magnetized portion of the tissue-penetrating medical device from being de-magnetized when the cover is positioned to cover the tissue-penetrating medical device.

This invention relates to coated mesoporous nanoparticles (MSN). The coating material is an ultrasound-responsive material (for example a polymer) and it acts as a control layer for blocking/release of material loaded in the pores of the MSN.
