Abstract

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.

Claims

1. A device for withdrawing or delivering a substance through the skin of a patient, said device comprising:

a support having a top end and a bottom end, said support having a plurality of channels extending from said top end to said bottom end;

a plurality of skin penetrating members disposed in said support wherein each of said plurality of skin penetrating members is positioned in a respective channel, each of said skin penetrating members having an exposed end extending from said bottom end of said support a distance sufficient to penetrate the skin of a patient; and

a coupling member attached to said support.

2. The device of claim 1, wherein said skin penetrating member is hollow for withdrawing or delivering a substance to said patient.

3. The device of claim 1, wherein said support includes a passage for withdrawing or delivering a substance to said skin penetrating member.

4. The device of claim 1, wherein each of said skin penetrating members has an exposed end extending from said bottom end of said support having a length of about 100 microns to about 2000 microns.

5. The device of claim 1, wherein each of said skin penetrating members has an exposed end having a length of about 500 microns to about 1500 microns.

6. The device of claim 1, wherein said coupling member is attached to said top end of said support and is adapted to be coupled to a fluid supply or fluid reservoir.

7. The device of claim 6, wherein said coupling member includes a Luer fitting.

8. The device of claim 6, further comprising a fluid supply coupled to said coupling member.

9. The device of claim 6, wherein said coupling member is a fluid coupling member and includes a cavity communicating with said at least one channel.

10. The device of claim 1, wherein said channels are spaced apart to define a substantially uniform array.

11. The device of claim 10, wherein said exposed end of each of said skin penetrating members has a length different from an adjacent skin penetrating member.

12. The device of claim 1, wherein said skin penetrating member has a first end substantially flush with said top end of said support.

13. The device of claim 1, wherein said skin penetrating member has a first end recessed in said channel and spaced from said top end of said housing.

14. The device of claim 1, wherein said skin penetrating member of about 30 to about 50 gauge.

15. The device of claim 1, wherein said skin penetrating member has an exposed length extending from said bottom end of at least 500 microns.

16. The device of claim 1, wherein said skin penetrating device is selected from the group consisting of hollow needles, solid needles, glass tubes and polymeric tubes.
