Abstract: A stent delivery system includes a handling device having a housing, a thumbwheel rotatably mounted in the housing, and a winding spool rotatable with the thumbwheel. A catheter arrangement has an inner shaft with an end fixed on the housing, an outer sheath disposed coaxially to the inner shaft, and a stent received radially between the inner shaft and outer sheath. A flexible pull member engages a proximal end of the outer sheath and is held on the winding spool to be windable. For release of the stent, the outer sheath is displaceable relative to the inner shaft by winding the flexible pull member on the winding spool. The winding spool has different winding diameters on which the flexible pull member engages and is windable in different displacement positions of the outer sheath. Different transmission ratios result between rotation of the thumbwheel and movement of the outer sheath.

Abstract: A stent delivery system includes a handling device having a housing, a thumbwheel rotatably mounted in the housing, and a winding spool rotating with the thumbwheel. A catheter arrangement includes an inner shaft fixed on the housing. An outer sheath is coaxial to the inner shaft. A stent is received between the inner shaft and outer sheath. A pull member engages the outer sheath and is held on the winding spool to be windable. For release of the stent, the outer sheath is displaceable by winding the pull member on the winding spool. A locking mechanism causes, upon reaching at least one defined angle of rotation of the thumbwheel, a locking state of the rotational mobility of the thumbwheel, and thereby of the proximal displaceability of the outer sheath. An unlocking mechanism is in operative connection to the locking mechanism. The locking state is reversible with the unlocking mechanism.

The cartridge may be released from the grip member using a release mechanism. The release mechanism may be part of a cartridge disposal system.

Abstract: A cartridge includes a body with a side wall and at least one lid arranged to cover a top or a bottom, or both. The cartridge comprises a cavity inside the body configured for receiving an aerosol-forming substrate. The lid includes an inner layer facing the cavity and an outer layer facing an outside of the body. The inner layer comprises a weakened region. When the outer layer is removed, the weakened region of the inner layer forms an aperture. The cavity is in fluid communication with an outside of the cartridge body via the formed aperture. The aerosol-forming substrate may include tobacco. The cartridge may be a shisha cartridge and the aerosol-forming substrate may be a shisha substrate, such as hookah tobacco.

Abstract: A printing fluid container (100) for use in a printing system is described. An example container includes a base (110) and a light transmissive side wall (120). The side wall extends from the base to define a chamber (130) for receiving and storing printing fluid within the container. The side wall has an internal surface (122) facing the chamber, said internal surface comprising a channel (140). The channel comprises a portion (142) indicating a height from the base, the height representing a predetermined fill amount. The channel is configured such that when the chamber contains printing fluid, printing fluid resides within the channel (140) and indicates the predetermined fill amount.
