Claim:
1. A medicament injection device for injecting a medicament to a tissue at a skin site of a patient, comprising: a device body portion that includes a penetrating member channel; a penetrating member with a sharpened distal tip and a shaft portion which is slidably disposed within the penetrating member channel to provide for the penetrating member to travel in a linear axial movement; a feedback loop coupled to a processor and to a controllable driver, the processor configured to storing penetrating member driver profiles in a memory, to selecting one of the penetrating member driver profiles from the memory, and actuating the penetrating member in accordance with the selected penetrating member driver profile to release the penetrating member for penetration of the skin site at an injection site, wherein the processor and the controllable driver operate with the feedback loop to control a depth of penetration to the injection site and a velocity of the penetrating member such that an insertion velocity of the penetrating member is greater than a withdrawal velocity of the penetrating member; a pierceable membrane that isolates the penetrating member in an associated penetrating member chamber; and a medicament reservoir in fluid communication with the penetrating member, the medicament reservoir configured to house a medicament, the medicament reservoir coupled to the penetrating member to allow for delivery of medicament to the injection site.
