The application relates to a catheter device with a distal bearing for bearing a distal end of a drive shaft. The distal bearing comprises a heat conducting part for enabling heat transfer away from the distal bearing and/or a spiral sleeve for receiving the distant end of the drive shaft.

A device and method for delivering a fluid as an ejected stream of droplets during inhalation uses inertial filtering to cause a first plurality of droplet particles generated by an ejector mechanism to pass through an airflow exit while a second plurality of droplet particles having a greater mass mean aerodynamic diameter than the first plurality of droplet particles fails to pass through the airflow exit.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.
