A device is provided that humidifies breathing gas. The device has a chamber with an inlet and an outlet. A chemical heater is positioned within the chamber and a trigger activates the heater. The chamber can be a conduit with an inner wall and an outer wall with a reservoir defined therebetween. The chemical heater can be positioned within the reservoir.

A cap assembly for a drug delivery device is present having a cap body to protect and to receive a distal dispensing end of the drug delivery device, an interlock member operably engaged with the cap body and being further adapted to releasably engage with a distal end section of the device's dispensing end to provide a safety lock for the cap body.

A wheelchair rear wheel support assembly and a detachable arm assembly is described. The rear wheel support assembly is adjustable by finite adjustment both in the horizontal and vertical planes whereby to adjust the position of the rear wheels at a center of gravity to suit a user person to optimize the efforts of propulsion of the wheelchair by the user and thereby significantly increasing its quality of life. The detachable armrest is easily adjustable in height and can be pivoted away from its position of use by simple hand-operating levers easily accessible to the user person. It can also be easily removed with little effort.

A medical safety needle includes a needle body having a needlepoint, a covering body having a detent portion slidable on the needle body to catch the needlepoint so as to cover the needlepoint, and a resilient cantilever supporting the detent portion, a collar portion slidably fitting on the covering body, which is configured to get in contact with the cantilever to press the cantilever radially inwardly, and a housing being formed in a unitary body with the collar portion or having an end face on which the collar portion is capable of being seated, the housing being configured to carry the covering body from a first position to have the needlepoint exposed to a second position to have the needlepoint covered by the covering body.

Fluid transfer systems are disclosed that can be configured to transfer precise amounts of fluid from a source container to a target container. The fluid transfer system can have multiple fluid transfer stations for transferring fluids into multiple target containers or for combining different types of fluids into a single target container to form a mixture. The fluid transfer system can include a pump and a destination sensor, such as a weight sensor. The fluid transfer system can be configured to flush remaining fluid out of a connector to reduce waste, using air or a flushing fluid.

The invention relates to an expansion device for bone expansion, wherein the expansion device has a proximal end and a distal end, between which ends the expansion device extends in a longitudinal direction, and extending apparatuses, which succeed one another in the longitudinal direction, wherein the extension apparatuses can be extended in order to exert force on a bone.

Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves. An annuloplasty ring includes an outer hollow body member including a plurality of regions. Adjacent regions cooperate with one another to change the body member from an elongate insertion geometry to an annular operable geometry. Adjacent regions are coupled by a biasing element or a stepped connector to allow expansion to an expanded state and contraction to a contracted state in the annular operable geometry. The annuloplasty ring also includes an internal anchor member located at least partially within the body member and having a plurality of anchors configured to attach the annuloplasty ring to tissue of a heart valve annulus. An angled ring closure lock allows coupling of the ends of an annuloplasty ring at an apex of a D-shape annular operable geometry.

A stapling assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a body portion comprising a porous material and a plurality of cavities defined in the body portion, wherein the cavities are aligned with forming surfaces of an anvil such that fasteners of a fastener cartridge are configured to at least one of the cavities when the fasteners are ejected from the fastener cartridge or capture the cavities and compress the cavities within the tissue thickness compensator when the fasteners are ejected from the fastener cartridge and formed by forming surfaces of the anvil. The stapling assembly further comprises at least one medicament positioned within each cavity prior to firing the stapler, wherein the medicament is different than the porous material.

An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

A respiratory apparatus may employ ultrasonic welds. The ultrasonic welding may be used to join a variety of headgear, mask and accessory components. This process may enhance comfort, fit and/or performance of the joined components and/or overall mask assembly. A component may be a single layer component such as a textile or fabric, or a composite or multiple layer component such as fabric and foam composites, or outer fabric layers and inner spacer fabrics. Further, a component may be a strap, some other headgear component, a mask component, an accessory component or the like.
