Abstract: A catheter insertion device (10) includes a housing (12) with a base (14), a catheter (28), an introducer needle (30) and an actuator (26) mounted within the housing. The catheter (28) and needle (30) are coupled to the actuator (26) and movable between a first position where the catheter and needle are retracted within the housing and a second position where the catheter (28) and needle (30) extend from the housing, and where the needle retracts into the actuator when the catheter and needle reach the second position. A spring (90) is provided in the housing (12) or the actuator (26) where the spring (90) is released after deployment of the device to retract the needle (20) with respect to the catheter (28).

Abstract: A pump subsystem for fluid delivery (e.g., in a wearable patch pump) is provided wherein pumping action is generated by linear piston movement that pulls a plug, which is interconnected to the piston between two mechanical extremes or end stops in a telescopic or variable volume fluid chamber. Such interconnection enables piston and plug to move a certain distance with respect to each other that corresponds to a predefined swept volume of the pump subsystem. Telescoping-like effect of relative piston and plug movement provides for intake and discharge of fluid with respect to the fluid chamber. Movement of plug within piston can be enabled by the friction of seals placed on the plug, which serve to provide resistance to piston motion and therefore force translation motion of the plug to lag relative to the piston translation motion during portions of the pump cycle.

Abstract: A cannula insertion device is disclosed. The device includes a needle carriage, a rail device on which the needle carriage is slidable, a yoke having a channel, a linkage connected to the needle carriage and extending into the channel, a torsion spring with one end connected to the linkage, and locking device for locking the torsion spring in tension and maintaining the needle carriage and the linkage in a locked position prior to activation. Upon release of the locking device, the tension of the torsion spring is released, which causes the linkage to move in the channel and slide the needle carriage along the rail device. A catheter carriage may also be provided for actuation by the linkage.

The actuator (26) has a detent (84) that engages a first recess (76) to require a predetermined force to depress the actuator (26) which is greater than the force necessary to slide the actuator (26) to the second position where the detent (84) engages a second recess (80) in the housing (12) to hold the actuator in the deployed position.

Abstract: A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The sleeve receives a gasket that forms a seal between the sleeve and the housing, the gasket having an opening surrounding a side hole of the sleeve to permit fluid to pass through the side hole between a pump volume and an inlet port or outlet port of the housing.

Abstract: An insulin infusion system is provided with a manual insertion device having a dual retraction spring (230) configuration for automatic introducer needle (222) retraction. A button (200) of the insertion device is used to insert the introducer needle (222) and catheter (202), and once the introducer needle (222) and catheter (202) have been fully inserted, a rotating engagement releases the dual retraction springs (230) such that the introducer needle (222) automatically retracts, leaving the catheter (202) in the body of the user. An end of the introducer needle (222) remains in the inserted catheter (202) and/or in the septum (206) of the inserted catheter (202) to provide an uninterrupted fluid path.
