An injector device for transcutaneously placing at least a portion of a cannula of a medical device through the skin of a patient is provided. The injector device includes a device housing having a bore formed therein and a plunger slidably received within the bore. The plunger includes an insertion needle secured thereto for receiving the cannula of the medical device. The insertion needle remains secured to the plunger subsequent to placement of the medical device and the insertion needle and the injector are removable from the cannula while maintaining the transcutaneous placement of the cannula.

An insertion device for inserting an infusion device at least partially into skin for subcutaneous infusion can comprise a sleeve having a lower surface that is configured to engage the skin, a shuttle or carriage to carry the infusion device between a retracted position and an advanced position; at least a first biasing member to urge the shuttle or carriage toward the advanced position, and an actuator to cause the first biasing member to urge the carriage from the retracted position to the advanced position. In some embodiments, the insertion device can further comprise a hub and at least a second biasing member to urge the hub away from the shuttle or carriage. In some embodiments, the insertion device can further comprise a needle attached to the hub. Methods for inserting an infusion device and various other features that can be comprised by an insertion device are also disclosed.

A subcutaneous infusion set. The subcutaneous infusion set may include a base for providing an infusion path; a cannula connected to and extending away from the base; a connector removably attachable to the base; and a tubing affixed to the connector. The connector may be limitedly rotatable on the base when the connector is removably attached to the base. Also, a contiguous pass for passing fluids may be formed from the tubing to the cannula when the connector is removably attached to the base.

A device for inserting a subcutaneous infusion device into skin of a patient. The device can include a housing (110), a needle hub (130) including a needle (336), a sleeve (140), and a spring (150) engaging the needle hub. The device can also include a cap (170) coupled to the housing, and a retention member (520, 540) configured to maintain the device in a ship state prior to decoupling of the cap from the housing. In one example, the retention member can include a boss coupled to the cap and configured to engage the infusion device to maintain the infusion device in the ship state prior to decoupling of the cap from the housing. In another example, the retention member can include a tab (540) formed by the sleeve, the tab engaging a bead (510) on an internal surface of the cap when the sleeve moves relative to the housing while the device is in the ship state.

This invention relates to a packing for an injector device for the placement of a subcutaneous infusion set on a patient. An insertion needle used in conjunction with an injector device is employed for transcutaneous placement of a soft and relatively flexible tubular cannula, followed by removal of the insertion needle and subsequent infusion of medical fluid to the patient through the cannula. The packing according to the present invention can storage an injector device combined with an infusion set and an insertion needle under sterile conditions. The packing comprises at least - a first storage room storing the injector device combined with an infusion set and an insertion needle, - a first part (1) providing a further storage room (9b) isolated from the insertion needle (312, 26), is constructed with a bottom part (2a, 2b) and walls (2c) standing upright form the bottom part (2a, 2b), - a second part which is attached to the first part (1) before use in such a way that the conditions inside the packing remain sterile, and seen from a sectional view through the walls (2c), the walls (2c) are forming at least two sections each formed as a partial circle with at least two centres C1 and C2 and the centres C1 and C2 are placed with a distance D between them.

A system for delivering fluid to a user transcutaneously includes a subcutaneous infusion cannula base assembly, a cannula inserter assembly and a fluid connection assembly. The subcutaneous infusion cannula base assembly is configured to be located on the user's skin. The cannula inserter assembly is coupled to the cannula base assembly and is configured to drive an infusion cannula through the user's skin in a nominally helical trajectory. The fluid connection assembly is configured to fluidically connect the cannula base assembly to a source of delivery fluid. Cannula and stylet assemblies configured for helical or non-helical insertion are also disclosed.

A needle stick prevention device (10, 110) includes a needle shield (20, 120) for selectively covering a distal end of a needle (41, 141). A needle hub (40, 140) is movably received within the needleshield (20, 120). The needle hub (40, 140) includes a proximal end (42, 142), a distal end (46, 146), a needle (41, 141) fixedly connected to the distal end of the needle hub (40, 140), and a plurality of ribs (54) or a cylinder (150) disposed between the proximal and distal ends. An actuation button movably received in a transverse opening of the needle shield (20, 120) to engage the needle shield (20, 120), the needle hub (40, 140) and a medical device. A spring (58, 158) is disposed between the needle hub (40, 140) and actuation member to automatically retract the needle (41, 141) into theneedle shield (20, 120).

The present invention provides infusion devices and methods for subcutaneous delivery of high viscosity fluids. The devices and methods described are innovative subcutaneous infusion systems that allow for the rapid delivery of viscous therapeutic fluids while avoiding adverse side effects and promoting patient comfort. The devices and methods described are also useful for rapid delivery of high volumes of therapeutic fluids.
