A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly including a particulate material. The delivery assembly further includes a multi-port needle with a top distal port and bottom proximal port(s), the needle configured to puncture a septum of the vial assembly when the vial assembly is in the locked position, in which the top distal port is at a distance above the particulate material in the vial assembly. The ports are configured to inject a fluid into the vial assembly to mix with the particulate material upon actuation of the vial engagement mechanism in a first direction and to receive a resulting mixed fluid from the vial assembly upon actuation of the vial engagement mechanism in a second opposite direction.

A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

A device for filling a reservoir. The device includes a cover portion comprising a septum window, and a bottom portion, the bottom portion configured to attach to a disposable housing assembly comprising the reservoir, wherein the cover portion and the bottom portion are rotatably attached in a locked configuration and wherein in a locked configuration, a septum is obscured through the septum window, wherein when the cover portion and the bottom portion are placed in an unlocked configuration, the cover portion rotates with respect to the bottom portion and the septum is visible through the septum window.

An injection device for subcutaneous delivery of fluid which comprises a puncture cannula and an indwelling cannula. In a starting position, a distal end region of the puncture cannula runs coaxially inside the indwelling cannula. The device comprises displaceably mounted first and second runners. The first runner is connected to the puncture cannula and the second runner to the indwelling cannula. A control element is movable over a predefined control area. The control element is configured such that, in a first part of the control area, the control element effects an equidirectional displacement of the first and the second runners, and hence fitting of the indwelling cannula and, in a second part of the control area, effects blocking of the second runner, and hence holding of the indwelling cannula in a dwell position, and return of the first runner and withdrawal of the puncture cannula into an end position.

A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes at least one optical sensor assembly configured to sense the movement of the pump assembly, a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

Guided relay infusion systems and methods are provided. A guided relay infusion system may be a portion of an infusion pump that can simultaneously deliver a medical fluid from two syringes. When a first one of the syringes is running out of the medical fluid and a second one of the syringes is more full of the medical fluid than the first one of the syringes, guided relay messages are provided for a relay handoff from the first one of the syringes to the second one of the syringes that ensures a smooth continuous delivery of more of the medical fluid than the first one of the syringes holds.

A filling aid device for filling a reservoir. The device includes a cover portion comprising a septum window; a slider beam comprising a septum cover; and a first filling aid tab attached to the slider beam, the first filling aid tab in slidable relation to the cover from a first position to a second position, wherein when the filling aid device is in an unlocked position, the septum cover is located below the septum window, wherein when the first filling aid tab is moved from the first position to the second position, the septum cover is moved from below the septum window, and the filling aid device is in the locked position.

A wearable infusion pump assembly includes a reusable housing assembly, and a disposable housing assembly including a reservoir for receiving an infusible fluid. The wearable infusion pump assembly also includes a releasable engagement assembly configured to allow the reusable housing assembly to releasably engage the disposable housing assembly. A switch assembly of the wearable infusion pump assembly is configured to effectuate a functionality of the infusion pump assembly.

A method for dynamic pressure control during a multiphase injection is described wherein the pressures of fluids in the various reservoirs of a fluid delivery system are controlled to provide desired fluid delivery parameters. The methods include advancing the first drive member to expel the first fluid from the first reservoir into a conduit, wherein the fluid is pressurized to a first fluid pressure; measuring the first fluid pressure to provide a target value; while the second reservoir is in fluid isolation from the conduit, advancing or retracting the second drive member to increase or decrease the fluid pressure of the second fluid in the second reservoir to the target value; placing the second reservoir in fluid communication with the conduit; and advancing the second drive member to expel the second fluid from the second reservoir into the conduit.
