Infusion device

An medicament delivery device, comprising:

• a housing;
• a compartment having a longitudinal axis and positioned inside the housing for holding a medicament container;
• a needle connected to a flexible tube and movably arranged within the housing and in fluid communication with the medicament container through the flexible tube for delivering a dose of medicament, where the needle has a proximal end that moves from a first position within the housing to a second position that is extended to a position outside the housing, where the movement of the needle from the first position to the second position defines an axis of movement;
• a piston plunger disposed in the housing for acting on the medicament container to deliver the dose of medicament, wherein the piston plunger moves parallel to the longitudinal axis of the compartment in a direction that is transverse to the axis of movement of the proximal end of the needle;
• and
• a driver operatively engaged with the piston plunger to deliver the dose of medicament;
• wherein when the medicament device is activated, the proximal end of the needle moves to the second position before delivering the dose of the medicament.
