Various systems and methods are provided for creating a wicking structure. In one example, a method for creating a wicking structure can include creating, using a 3D printing technique, a macro wicking element including a lattice structure formed by a grid of a first material, the lattice structure including pores formed between the grid of first material. The method can also include creating, using the 3D printing technique, a first micro wicking element including powder particles distributed within the pores of the lattice structure, and creating, using the 3D printing technique, a second micro wicking element by removing at least a portion of the lattice structure.

A system to be used inside a dialysis unit for dilating obstructed blood vessel, comprises a catheter, a device, a remote-control box, supportive components and connection cables. A catheter comprises an elongated portion, a proximal end and a distal end, extended longitudinally. A distal end of a catheter has a convectively heating tip with a heat generating element and an inflatable balloon. A device has a radiofrequency current generator to supply and control a heating process of a heat generating element of a catheter tip. A remote-control box comprises a valve assembly, a heat activation switch and a balloon inflation switch to facilitate a treatment process.

A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first heater, a second heater, and a frame sandwiched between the first heater and the second heater, and a cannabinoid-containing material. The frame may define open spaces therein and have a rigidity that is adequate to support the first heater and the second heater. The open spaces within the frame may be interconnected and sized for aerosol-permeability and capillary action.

Apparatus and methods for generating an inhalable medium are disclosed. An apparatus includes a container for holding a liquid, a heater for volatilizing liquid held in the container to generate a flow of at least one of a vapor and an aerosol in use, and a receptacle for receiving material. The receptacle is located adjacent to the heater such that in use, material received in the receptacle is heated by the heater. One or more constituents of material received in the receptacle in use are mixed with the flow of at least one of a vapor and an aerosol in use to produce the inhalable medium.

A heating apparatus includes a heating element which converts electrical power to heat energy, a heatable element having a first surface and a second surface, and a dielectric laminate layer between the heating element and the first surface of the heatable element, wherein the dielectric laminate layer is thermally conductive to transfer heat energy from the heating element to the heatable element, and wherein the second surface of the heatable element is configured heat a liquid in a container.

An intravascular blood pump having a rotatable shaft carrying an impeller and a housing with an opening through which the shaft extends with the impeller positioned outside the housing. The shaft and the housing have surfaces forming a circumferential gap which converges towards the impeller-side end of the gap and which has a minimum gap width of preferably no more than 5 μm, more preferably no more than 2 μm.

A hookah device (202) which attaches to a hookah (246). The hookah device (202) comprises a plurality of ultrasonic mist generator devices (201) for generating a mist for inhalation by a user. The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

The invention relates to a liquid store for an inhaler (10), in particular for an electronic cigarette product, having an outlet end (53) which can be fluidically connected to a heating element (60) in order to evaporate liquid (50) supplied to the heating element (60) from the liquid store (18). The liquid store (18) has at least one air inlet end (52) and at least one channel (51). The channel (51) extends from the air inlet end (52) to the outlet end (53) through the liquid store (18), wherein the channel (51) is designed to transfer the liquid (50) stored in the liquid store (18) to the outlet end (53) through the channel (51) via capillary forces.

A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first heater, a second heater, and a frame sandwiched between the first heater and the second heater, and a cannabinoid-containing material. The frame may define open spaces therein and have a rigidity that is adequate to support the first heater and the second heater. The open spaces within the frame may be interconnected and sized for aerosol-permeability and capillary action.

A vaporiser insert for an electronic cigarette product comprises at least one electrical vaporiser for vaporising fluid supplied to the vaporiser and for supplying the vaporised fluid to an airflow, a main part having a lateral face which surrounds an airflow duct through which the airflow can flow, at least one fluid opening for supplying vaporisable fluid from the outside into the vaporiser insert and to the vaporiser being arranged on the lateral face of the main part. The vaporiser insert comprises a support for retaining the vaporiser, and the support comprises a passage opening that corresponds to the fluid opening in order to supply fluid to the vaporiser.
