Patent ID: 6896666

Claim:
A device for delivery of a fluid cutaneously comprising: a) a housing having a peripheral edge; b) a needle in the housing for piercing a cutaneous layer; c) a bladder for containing fluid for injection below the cutaneous layer; d) an area transversely within the peripheral edge of the housing and through which the proximal end of the needle may be directed, and the area being for receiving the surface of the cutaneous layer about which the proximal end of the needle is to pierce to effect an injection of fluid; and e) a suction generator for creating a suction force at the area thereby to urge the cutaneous layer towards the area within the peripheral edge of the housing and thereby provide a stabilizing force to the cutaneous layer; f) the arrangement of the needle, bladder and suction generator being such that the needle is caused to move by the suction force through the transverse area and thereby pierce the surface of the cutaneous layer; and permitting the expulsion of fluid from the bladder into the distal end of the needle and thereby permit the expulsion of fluid through the proximal end of the needle.
