Abstract: Embodiments of the present disclosure relate to techniques, processes, devices or systems for pump devices. In one approach, a wearable drug delivery device may include a reservoir configured to store a fluid, the reservoir including a housing defining an interior chamber. The wearable drug delivery device may further include a drive device for driving the fluid from the reservoir, the drive device including a plunger head within the interior chamber of the housing, and a plunger shaft extending from the plunger head. The plunger shaft may include a first component adjacent a second component, wherein during movement of the plunger head in a first direction the first and second components engage one another to form a rigid portion of the plunger shaft, and wherein during movement of the plunger head in a second direction, opposite the first direction, the first and second components are separated from one another.

Abstract: Exemplary embodiments may terminate application of an electric pulse to a shape memory alloy (SMA) element that causes actuation of a medicament pump based on resistance values unlike conventional approaches that rely on a mechanical mechanisms to trigger termination of the application of the electric pulse. The magnitude of the resistance values, the rate of change (RoC) of the resistance values, the temperature of the SMA element, the time that has passed since initial application of the electric pulse to the SMA element, or combinations thereof may be used to trigger the termination of the application of the electric pulse to the SMA element in exemplary embodiments. The monitoring of the resistance of an unactuated SMA element may be used to determine when to initiate and when to terminate application of an electrical pulse to the other SMA element.

Abstract: Disclosed herein are various embodiments of clutching mechanisms applicable to a dual reservoir pumping mechanism for a drug delivery device, the clutching mechanisms serving to allow translation of one of the reservoirs during the filling process and thereafter connecting the reservoirs together such that one can be driven relative to the other one by means of a leadscrew or other driving mechanism.

Abstract: Disclosed herein are devices and methods for causing the linear translation of a plunger through a reservoir containing a fluid. A flexible member, for example, a wire or a ribbon, is coupled to the plunger and extends through a wall of the reservoir toward which the plunger is being linearly translated. A pulling force on the flexible member caused by a drive mechanism causes the plunger to linearly translate toward the end wall of the reservoir, thereby forcing any fluid contained in the reservoir out of the reservoir through a fluid port.
