A catheter assembly includes an outer shaft having an outer shaft body forming an outer shaft bore that receives an inner shaft. The outer shaft has a wire transition section. The catheter assembly includes an exit path connector coupled to the outer shaft body at the wire transition section. The exit path connector has a rigid body section separate and discrete from the outer shaft body and coupled to the outer shaft body. The body section defines an exit path connector bore that receives the inner shaft. The body section has a side exit port at a side of the body section being open to the exit path connector bore. The catheter assembly includes a catheter wire passing through the side exit port from an interior to an exterior of the cable exit port.

Disclosed is an intravenous drug dispensing kit including: a cylinder cartridge for introducing and discharging external fluids through changes in the volume of a cylinder occurring when a pair of first and second pistons disposed therein is fixed and rotates relatively to each other; a first tube connected to an outlet tube of the cylinder cartridge; a three-way valve having a first introducing flow path, a second introducing flow path, and a discharge flow path connected to any one of the first introducing flow path and the second introducing flow path; a second tube for connecting the discharge flow path of the three-way valve to an inlet tube of the cylinder cartridge; a third tube connected to the first introducing flow path of the three-way valve; and a fourth tube connected to the second introducing flow path of the three-way valve.

Connectors are disclosed that include an outer connector, inner connector, and a clutch that can collectively limit a torque transmitted through the connector. The outer connector includes a profile disposed on an inner surface of the outer connector, and the inner connector may be disposed within the outer connector and can include an upper threaded portion and a lower threaded portion. The clutch can be disposed around and rotationally coupled to the inner connector and can include a plurality of clutch teeth extending from an outer surface of the clutch, wherein the plurality of clutch teeth are outwardly biased to be releasably engaged with the profile of the outer connector. The plurality of clutch teeth can be configured to transfer torque from the outer connector to the inner connector when the torque is below a torque limit, and prevent transfer of torque when the torque exceeds the torque limit.

A connector for connecting a tube to a connection element. The connector includes a housing, which has a coupling portion. The coupling portion is adapted to be at least substantially fluid-tightly connectable to a complementary connection portion of the connection element. The connector includes a tube connection piece, which is adapted to be connectable on the one hand to a tube and on the other hand to the housing in order to make a fluid connection between the tube and the coupling portion of the housing. The housing includes at least one polyolefin.

A catheter assembly may include an introducer needle coupled to a needle hub, an intermediate member having a contact surface, a resilient member, and a ramp member. The resilient member may be coupled to one of the needle hub and the intermediate member. The ramp member may be coupled to the other one of the needle hub and the intermediate member. The resilient member may engage a ramp surface of the ramp member and impart a force on the intermediate member in a distal direction. The contact surface of the intermediate member may engage a proximal surface of a catheter adapter body and urge the catheter adapter body in the distal direction such that a catheter projecting from the catheter adapter body may be translated in the distal direction relative to the introducer needle.

A connector for coupling an enteral feeding solution supply tube to a port of a gastrostomy device, comprising a fluid conduit having an upstream end and a downstream end; and a nozzle housing a first portion of the fluid conduit at the downstream end configured to be connectable to an orifice defined in the port of the gastrostomy device. The nozzle has a proximal end, a distal end and a longitudinal axis extending therebetween. An external diameter of the nozzle at or adjacent the distal end is substantially equal to an external diameter of the nozzle at or adjacent the proximal end. An external surface of the nozzle includes one or more indentations. The invention also relates to a feeding extension set including a connector and an enteral feeding solution supply tube.

A catheter system may include a cap, which may include a top. The cap may include a male luer extending distally from the top and inserted into a proximal end of a female luer adapter of the catheter system. The cap may include a first arm and a second arm extending distally from the top. The first arm may include a first slot, and the second arm may include a second slot. The first protrusion may be disposed within the first slot and the second protrusion may be disposed within the second slot. The cap may include a collar extending distally from the top. An inner surface of the collar may include a first undercut and a second undercut. The first protrusion may be disposed within the first undercut and the second protrusion may be disposed within the second undercut.

A female connector that allows connection of a male connector including a lock claw and a channel connection. The female connector includes a cap including a top provided with an opening and a peripheral wall extending from an outer peripheral edge of the top; a housing including a cylindrical wall and an engaging protrusion protruding from an outer peripheral surface of the cylindrical wall to form a lower surface engaged with the lock claw; and a valve including a portion sandwiched between the top and the cylindrical wall and a portion penetrating the valve in up-and-down direction. A boundary is formed between an upper surface of the engaging protrusion and a lower end face of the peripheral wall. The lower end face is smaller than the upper surface in outer diameter. The engaging protrusion has an outer peripheral surface including a portion with a diameter increasing downward from the boundary.
