Abstract: Fluid delivery systems, methods and devices for delivering a therapeutic fluid to the body of the patient are disclosed. A fluid delivery device for delivering fluid to the body of the patient includes a housing having an upper wall, a lower wall, and an opening. The device includes a well-arrangement mechanism disposed inside the housing. The well-arrangement mechanism includes a tubular member having a bore disposed between the wall openings. The device also includes a penetrating cartridge for delivery of therapeutic fluid to the body of the patient. The cartridge is configured to engage the bore following its insertion through the opening such that the therapeutic fluid can be delivered through the tubular member into the penetrating cartridge, and into the body of the patient, when the penetrating cartridge engages the bore.

Abstract: A portable therapeutic fluid delivery device and a method for delivering a therapeutic fluid into a body of a patient are provided. In one aspect the therapeutic fluid delivery device and the method can be implemented using at least one housing securable to the body of the patient, a reservoir coupled to the at least one housing, a therapeutic fluid dispensing mechanism, a memory component, a controller, at least one bolus delivery button configured to signal the controller to initiate the delivery of the therapeutic fluid into the body of the patient; and, an inadvertent initiation prevention mechanism adapted for preventing the patient from activating the at least one bolus delivery button.
