Apparatus and methods for medicament delivery. The apparatus may include, and the methods may involve, a delivery device for delivering a target amount of the medicament from a distal end of the device. The device may include a rod for moving a plunger that discharges the medicament from the distal end. The device may avoid or reduce deformation of the plunger during the discharge. The plunger motion may be stopped by detent that interacts with the rod. The apparatus and the methods may provide an operator indication of progress of stages of operation. The device may feature triggers corresponding to stages of medicament displacement from the device, such as pre-delivery stages, including priming. |
