An implantable diaphragm pump for use in medical applications comprising a
housing having a pump cap, a valve plate, a diaphragm, and a base plate,
wherein the pump cap and the valve plate are separated by the diaphragm,
and the valve plate and lower surface of the diaphragm serve to form a
pump chamber. A permanent magnet is attached to the pump cap within the
diaphragm chamber wherein the lower surface of the permanent magnet is
adjacent to the upper surface of the diaphragm. The diaphragm having a
coil and a corrugated outer periphery, wherein when electrical current
flows in a first direction through the coil, the diaphragm engages the
lower surface of the permanent magnet, and when electrical current flows
in a direction opposite the first direction, said diaphragm engages the
upper surface of the valve plate.
