The invention relates to a nicotine containing cartridge assembly for use in a medical electronic nicotine delivery device, having a prolonged life time that remains over the treatment period, wherein the treatment is to help a person stop smoking.

An atomizing structural member includes an atomizing core assembly and a heating element; the atomizing core assembly includes an atomizing portion and a liquid guiding portion, the heating element is embedded in the atomizing portion, and the atomizing portion is an article of porous material; the liquid guiding portion is arranged to be in contact with the atomizing portion, and the liquid guiding portion is used to deliver an atomizing medium to the atomizing portion; the atomizing portion has an inner wall and an outer wall, the inner wall forms a first atomizing face and a first air channel that delivers aerosol generated from the first atomizing face, the outer wall forms a second atomizing face, and the liquid guiding portion is provided with at least one opening to form a second air channel that delivers the aerosol generated from the second atomizing face.

A pressurization device, for pressurizing an aerosol generating article, includes: a pressurization portion that is configured to be moved by a force applied by the aerosol generating article such that the pressurization portion pressurizes the aerosol generating article to induce a chemical reaction that generates an aerosol inside the aerosol generating article.

An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

An aerosol-generating device is provided, including a reservoir configured to hold a liquid; a release medium; and a heater, wherein the reservoir and the release medium are configured to transport liquid from the reservoir to the release medium, wherein the release medium and the heater are disposed in physical contact with each other, wherein the aerosol-generating device further includes a means for reversibly releasing the physical contact between the release medium and the heater to form a gap between the heater and the release medium, and wherein the aerosol-generating device is configured to activate the heater when the gap is formed between the heater and the release medium. A method for forming an aerosol by the aerosol-generating device is also provided.

A dynamic output power management unit for a heating circuit (100) of an electronic smoking device is disclosed, the heating circuit (100) having a heating element (10) connected to a power source (20) via a first switching element (30), the unit having at least one voltage detection device to detect voltage values at various points of the heating circuit (100); and a controller (2) configured to deriving a resistance of the heating element (10), estimating a discharge time or a power consumption value of the power source (20) such that an energy converted in a period of time is substantially identical to a predetermined energy conversion value for a same period of time.

A novel disposable cartridge for use in an electronic nicotine delivery system having an electric heater includes a reservoir containing a nicotine-containing liquid, a port in liquid communication with the reservoir, a liquid barrier disposed proximate the port to prevent undesired leakage of the nicotine-containing liquid from the reservoir, and a durable, elongate wick arranged and configured to be slideable in the port and to contact the nicotine-containing liquid in the reservoir.

An apparatus for extracting a compound from a substance comprising an extraction chamber arranged to extract a compound from a substance stored within the extraction chamber, wherein the extraction chamber is arranged to agitate the substance; and when upon the substance is under an applied heat, the extraction chamber is arranged to extract the compound into an air flow passing through the extraction chamber.

A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.
