Abstract
An infusion pump includes a plurality of projections configured so that they enter the subcutaneous region of the patients skin and provides a painless means of creating a breach in the stratum corneum which is sealed against leakage by the skin surrounding each projection and provides a flow path for either a basal and bolus injection of medication. The pump includes a drug reservoir containing a drug. The pump includes a microactuator and includes a housing having a foundation or lid which opens and closes so that the medication container can be inserted and supported in a delivery mode position. A micro actuator is used to advance either a roller or a piston in communication with the medication container. Attached to the micro-actuator is a device that is mounted for movement along the access of the medication container. The device indexes along the medication container that is used to dispense the medication.

17. A device useful for dispensing a liquid comprising:
-
a plurality of needles, said needles each including a sharpened end;
a base including bores in which the needles are at least partially inserted and said sharpened end extends outwardly therefrom, a cap sealingly mounted to the base and forming a plenum space with the base, the plenum space, the plenum space thereby creating passageway in fluid communication with the needles. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A device for infusing a liquid, comprising:
-
a hub dimensioned to be positioned against the skin;
a plurality of needles extending from the hub, the needles being dimensioned to penetrate the skin to a depth that goes beyond the superficial vascular plexus, but not as deep as the deep vascular plexus; and
a connecting tube attached to the hub, the connecting tube being in fluid communication with the plurality of needles. - View Dependent Claims (27, 28, 29, 30, 31, 32)

40. An integrated infusion device comprising:
-
a) a skin interface unit having two or more infusion pathways for supplying a fluid into the skin;
b) a pump integral to said skin interface and attached to said skin interface said pump including a pumping mechanism capable of pumping fluid in indexable discrete steps, to provide stepwise infusing of fluid into the skin through said skin interface unit. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

- 55. A method of manufacturing a device for infusing fluids through a least one needle having a base, a cap and at least one need having its sharpened end extending from the interior of the base to a point outside the base, the method comprising applying pressure to the base and cap to cause the cap to bend that portion of the needle which extends beyond the base to be bent in response to impingement by the cap.
