    摘要: A device includes a plurality of skin penetrating devices for delivering or withdrawing a substance through the skin of a patient. The device has a support formed with a top and bottom end and a plurality of channels extending axially through the support. A plurality of the skin penetrating members is positioned in the channels with a tip extending from the bottom end of the support. A coupling member is attached to the support for coupling with a fluid supply and directing the fluid to the skin penetrating members. The skin penetrating members have a length of about 100 microns to about 2000 microns and are about 30 to 50 gauge.

    摘要: The present invention provides improved methods for ID delivery of drugs and other substances to humans or animals. The methods employ small gauge needles, especially microneedles, placed in the intradermal space to deliver the substance to the intradermal space as a bolus or by infusion. It has been discovered that the placement of the needle outlet within the skin and the exposed height of the needle outlet are critical for efficacious delivery of active substances via small gauge needles to prevent leakage of the substance out of the skin and to improve absorption within the intradermal space. The pharmacokinetics of hormone drugs delivered according to the methods of the invention have been found to be very similar to the pharmacokinetics of conventional SC delivery, indicating that ID administration according to the methods of the invention is likely to produce a similar clinical result (i.e., similar efficacy) with the advantage of reduction or elimination of pain for the patient. Delivery devices which place the needle outlet at an appropriate depth in the intradermal space and control the volume and rate of fluid delivery provide accurate delivery of the substance to the desired location without leakage.
