  • Patent number: 5908414
    Abstract: An improved implantable infusion pump comprises a propellant chamber, a medicament chamber, and a throttle section. Enclosed within the throttle section is a medicament delivery system comprising a chip having a fluid path etched in an upper surface, inlet and outlet depressions formed in the chip lower and upper surfaces respectively, and a channel formed through the chip connecting the inlet with the fluid path. A planar cover, preferably transparent, covers the chip upper surface. A pair of wafers surround the chip within the throttle section and pair of silicon coatings are positioned between the chip and the pair of wafers. Various bores, apertures, and recesses are formed in the wafers, the cover, and the coatings, for permitting the medicament fluid to pass through the throttle section. An alternate embodiment employs a plurality of fluid paths and a plurality of outlets permitting different throttle resistance.
