Abstract: A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.

Abstract: A medicament delivery device may comprise a medicament chamber configured to hold a medicament, a plunger configured to move relative to the medicament chamber to expel the medicament from the medicament chamber, a pin configured to move from a first pin position wherein the pin prevents movement of the plunger to a second pin position wherein the pin allows movement of the plunger, an actuation assembly configured to move the pin from the first pin position to the second pin position, and a needle coupled to the medicament chamber. The medicament may flow through the needle from the medicament chamber to a user. The actuation assembly may be configured to automatically move the pin after a predetermined time delay.

Abstract: A medicament delivery assembly comprises a delivery device configured to deliver medicament to a user, a communication accessory releasably coupled to the delivery device, and one or more sensors configured to sense a condition of the delivery device. The communication accessory may be configured to receive a first signal from the one or more sensors assembly and to send a second signal to an external device.

Abstract: A fluid delivery device comprises a hydraulic pump chamber having a hydraulic fluid. A fluid reservoir is coupled to the hydraulic pump chamber and is configured to contain a fluid deliverable to a patient. A first actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir. A second actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir.

Abstract: A fluid delivery device for administering a first medicament and a second medicament includes a first fluid reservoir configured to contain the first medicament and a second fluid reservoir configured to contain the second medicament. The fluid delivery device may include one or more basal drive mechanisms to provide a basal delivery of one or more of the first and second medicaments. The fluid delivery device may further include one or more bolus drive mechanisms to provide a bolus delivery of one or more of the first and second medicaments.

Abstract: A fluid delivery device comprises a housing having a fluid reservoir. A needle is in fluid communication with the fluid reservoir in an engaged position and out of fluid communication with the fluid reservoir in armed and storage positions. A proximal end of a biasing member is coupled to the housing and a distal end of the biasing member is configured to deliver a force to the fluid reservoir. A piston member extends through the biasing member and is coupled to the distal end of the biasing member. The piston member is fixed with respect to the housing in a locked position such that the biasing member does not deliver the force to the fluid reservoir and moveable with respect to the housing in a released position such that the biasing member delivers the force to the fluid reservoir. Transitioning the needle from the storage position to the armed position transitions the piston from the locked position to the released position.

Abstract: A fluid delivery device comprises a housing having a base including a bottom surface; a locking assembly including a cartridge receiver configured to receive a cartridge, the cartridge having a fluid reservoir and a septum configured to be generally perpendicular to the bottom surface when the cartridge is engaged with the cartridge receiver; and a needle assembly having a needle, the needle having a delivery end, a fluid coupling end, and a central portion located between the delivery end and the fluid coupling end, the needle assembly configured to move in laterally relative to the base to a first position and vertically relative to the base to a second position. The locking assembly prevents the needle assembly from moving to one or both of the first and second positions unless the cartridge is engaged with the cartridge receiver.
