A needle insertor for a medicament delivery device is presented having a driver having a first part movably arranged within the case and a second part connected to the base, a needle assembly movably held by the first part in the case, a rotator arranged in the case and configured to engage the first part for moving the driver, an energy accumulation member configured to interact with the rotator for applying a rotational force on the rotator, a movable stop arranged on the base and configured to interact with the rotator for preventing the rotator from rotating. The first part has a first position where the needle assembly is held inside the case, a second position where the needle portion is positioned outside the case after being moved to pass through the injection site end, and a third position where the needle portion is positioned inside the case.

An on-body injector includes a drug reservoir having an outlet. First and second pistons may be positioned within the reservoir, with the second piston first being moved to open the outlet, followed by the first piston being moved to convey a drug from the reservoir via the outlet. The reservoir may instead include a cover, with a valve positioned between the outlet and the cover. The valve is rotated to place a channel of the valve in fluid communication with a through-hole of the cover, allowing flow from the reservoir via the outlet. The reservoir may instead include a valve movable from a condition in which it deforms the outlet, preventing flow through the outlet, to a condition allowing flow. The reservoir may instead include a seal that is deformed by an increase in pressure within the reservoir, with the deformed seal being open to allow flow through the outlet.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

A wearable infusion pump allows a user to insert a program key into a housing of the pump to select a continuous dosage rate. Program keys are shaped to close contacts on a printed circuit board within the housing to communicate the selected dosage rate to a microprocessor. In this way, a single disposable pump, sold with one Stock keeping unit (SKU), can be used to deliver a plurality of dosage rates. The disposable pump is provided with an on-board display and a one-button on-board user operable control. In preferred embodiments, the infusion pump according to the invention may be used for continuous delivery of insulin in management of Type II diabetes.

Glucose control systems are disclosed. An ambulatory medicament pump that is configured to wirelessly transmit one or more of a plurality of glucose control parameters and glucose control therapy data to a second ambulatory medicament pump is disclosed. A control system for transferring historical pump data from a first ambulatory medicament pump to a second ambulatory medicament pump is also disclosed. The control system can receive the historical pump data from a first ambulatory medicament pump, determine that at least one of a plurality of pairing conditions is satisfied to connect the data interface to the second ambulatory medicament pump, transmit, via the data interface, a pairing signal to the second ambulatory medicament pump, and transmit at least one of the therapy data associated with the delivery of the glucose control therapy or the glucose control parameter.

A patch pump system that has an electronic assembly, a reservoir for containing a fluid, and an inserter for selectively transitioning a needle from a retracted position to an extended position. The inserter provides a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir. The needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle.

An inserter assembly that has a base, a needle, an inner part that selectively transitions the needle from a retracted position substantially within the base to an extended position where at least a portion of the needle extends outside of the base, and an insertion angle component. As the inner part of the inserter assembly transitions from the retracted position to the extended position, the needle is at least partially deflected by the insertion angle component.

A wearable fluid metering device for delivering medication subcutaneously, intramuscularly or intravenously to a patient, includes a polymer actuator pump. The polymer actuator pump is flexible so it will conform to shape and yet can be used to rapidly displace a volume within a confined area. The actuator is much faster than prior art polymer actuator designs and can be actuated in multiple ways including introduction and hydration of the polymer matrix by a solution or the actuator can be actuated via pH change while it is in solution. The pH change can be made via electrical current such as that used in electro chemistry or the pH change can be made via a chemical change introduced to the actuator hydrating solution.

An automatic needle insertion device assists patients who may be uncomfortable with placing the needle themselves and employs a soft outer needle inserted using a rigid stylet, for example, a standard hypodermic needle, which is then removed after the soft needle is placed, greatly reducing irritation. An ambulatory pump can be filled with a variety of drugs and different amounts of drug on demand, for example, using a syringe prior to use.
