A connector device for gastric calibration hoses, including a first end and a second end opposite the first end. A first connector is disposed at the first end and a second connector is disposed at the second end. The first and the second connector are connected with each other via a fluid channel. The first connector includes a first tapering cavity sized and shaped to receive and couple with a gastric calibration hose. The second connector includes a second tapering cavity and a tapering recess annularly surrounding the second tapering cavity. The second tapering cavity and the tapering recess are sized and shaped to alternatively couple with different medical devices by receiving therein tubular structures of the different medical devices.

A respiratory mask includes a frame and a cushion module including a housing and a cushion that seals on a user's face in use. The housing includes a first connector, for example, a female connector, and the frame includes a second connector, for example, a male connector. The first and second connectors are coupled together in use. The housing includes one or more fasteners that secure the male connector to the female connector. Each fastener includes a base portion coupled to the housing and a moveable portion pivotally connected to the base portion. To assemble the mask, the male connector is inserted into the female connector such that the male connector engages the fasteners. Advancement of the male connector into the female connector causes the fasteners to change orientation from a neutral position to a toggled position and compress. The compressed fasteners apply a retention force to the male connector.

A female syringe of a syringe kit includes a female syringe barrel including a cylindrical portion into which a nozzle of a male syringe is insertable, a hollow cylindrical packing arranged in the cylindrical portion, and a cap detachably attached to the cylindrical portion. When the cap is detached from the cylindrical portion, the packing remains in the cylindrical portion, a distal end opening is opened, and the nozzle of the male syringe is fitted in a liquid-tight manner to an inner side of the packing.

An intravenous (IV) line set includes a tubing defining a fluid lumen, and first and second connectors attached at opposite ends of the tubing. The tubing is adapted to be formed into a shape and retain the formed shape. In an embodiment, the shape is retained via one or more malleable filaments extending along a length of the tubing. In another embodiment, the shape is retained via magnets.

A cap configured to engage different types of connectors includes a housing, an absorbent support, and a seal. The housing includes a sidewall extending between a first end and a second end of the housing. The absorbent support is positioned in the housing. The seal is mounted to a portion of the absorbent support and is configured to cover an opening of a first connector or a second connector when one of the first connector or the second connector is inserted into the housing. The cap is configured to be secured to the first connector by an engagement between a portion of an inner surface of the sidewall of the housing and the first connector and to the second connector by an interference engagement between another portion of the inner surface of the sidewall of the housing and an outer surface of the second connector.

A suspension of a therapeutic substance (e.g., embolic beads) dispersed within a liquid can be delivered via a catheter by using a bidirectional pump to rapidly draw the mixture of the therapeutic substance and liquid from an external syringe into an internal reservoir, then rapidly push the mixture back out into the external syringe. The rapid operation of the bidirectional pump mixes the two constituents so that the therapeutic substance is temporarily suspended within the liquid. Then, a low-speed pump is used to inject the mixture out via the catheter. In some embodiments, the parameters of the low-speed pump are controlled so that the fluid exiting the catheter will experience laminar flow. When the therapeutic substance comprises embolic beads, this can advantageously prevent reflux of the embolic beads, which can be dangerous.

A catheter system may include a luer adapter, which may include an outer surface having threading or a recess. The catheter system may also include a flow control plug, which may include a proximal end and a distal end. The proximal end of the flow control plug may include a filter element permeable to air and not to blood. The distal end of the flow control plug may include a cylinder and a taper-shaped luer tip spaced apart from the cylinder. An inner surface of the cylinder may include a protrusion engaged in a snap-fit with the recess or corresponding threading mated with the threading.

A cap for a fluid line connector having a male luer lock fitting, the cap having a first side and a second side opposite the first side, the cap comprising a barrier and a stopper extending axially from the barrier towards the first side of the cap. The barrier defines a keyway centred on a longitudinal axis. The shape of the keyway is configured to permit a correspondingly-shaped female luer lock fitting to pass axially therethrough to engage the male luer lock fitting of the fluid line connector. The stopper is configured to prevent rotation of the correspondingly-shaped female luer lock fitting in the first circumferential direction when a lug of the correspondingly-shaped female luer lock fitting is circumferentially aligned with the stopper.

Aspects of the present disclosure provide a fluid connector assembly, comprising a housing, comprising an upper housing including a female luer port, a lower housing including a male luer port and a cannula flow channel passing through the male luer port, and an internal volume fluidly connected to a first end and a second end and an elastomeric valve disposed in the internal volume, the elastomeric valve comprising a cavity, wherein when the male luer port is inserted into the female luer port of the upper housing, the elastomeric valve is configured to be stretched and pushed downwards, allowing a tip of the male luer port to interface with the cannula flow channel and for fluid to flow through the fluid connector assembly.

A morselizer comprising (a) a hollow cylindrical structure with an inner wall and an outer wall and comprising a first end section, a second end section, and a center section extending axially between the first end section and the second end section providing a substantially axial liquid pathway therein; (b) wherein each end section comprises a axially and radially hollow luer fitting that is attachable to a structure with a complementarily sized luer fitting; and (c) one or more blades extending transversally across the inner diameter of the center section wherein (i) each blade is comprised of a plurality of ends, including a posterior end secured to at least the center wall section inner wall at a center section inner wall first position and an anterior end proximal a center section inner wall second position opposite the center section inner wall first position, with a gap positioned between the blade anterior end and the center section inner wall second position, and (ii) at least two ends comprise cutting ends.
