Abstract

A method and device for the delivery of a substance into skin via the rotational movement of a microabrader device reduces the effects of operator variability. The method includes applying a substance to an area of a patient's skin through the rotational movement of microprotrusions. The movement of the microprotrusions can be imparted by a spring device or the like present in the microabrader device or the motion of the operator through the handle of the microabrader device. The rotational motion localizes the administration of the drug or vaccine dosage in the abraded skin area. The device can include means for monitoring pressure of the device against the skin and thereby promote consistency between applications and control of penetration depth. The substance, drug or vaccine may be placed on the microprotrusions and a reconstituting liquid included in the microabrader device.

Claims (10)

1. A rotary abrader device comprising:
a housing comprising at least one housing element, wherein said at least one housing element is selected from the group consisting of an upper housing, a lower housing, an internal housing, an external housing, and combinations thereof;
at least one housing element adapted to rotate;
at least one array of microprotrusions adapted to disrupt the skin of a subject when rotated;
a mechanical rotating means for mechanically rotating said at least one array of microprotrusions against the skin of a subject with sufficient force to disrupt and substantially penetrate the stratum corneum of the subject without piercing said stratum corneum.
2. The rotary abrader device of claim 1, further comprising at least one substance delivery port adapted for applying a substance to the skin of said subject at a delivery site prior to or simultaneously with the mechanical rotation of said array at said delivery site.
3. The rotary abrader device of claim 2, wherein the housing further comprises at least one stationary element.

3. The rotary abrading device of claim 3, wherein the at least one element adapted to rotate is further adapted for manual rotation.
4. The rotary abrader device of claim 1, further comprising:
an interlock mechanism disposed within said abrader housing for holding said microabrader array stationary until deactivated
5. The rotary device according to claim 4, wherein said interlock mechanism comprises:

a button protruding through the abrader housing, said button being coupled to a longitudinally moveable rod; and a spring within said abrader housing and surrounding said longitudinally moveable rod, wherein said microabrader array is coupled to an end of said longitudinally moveable rod so that said spring holds said microabrader array stationary until said button is depressed thereby deactivating said interlock mechanism.
6. The rotary device according to claim 5, further comprising a freely rotatable sleeve mounted within said abrader housing, said sleeve having an end face to which said microabrader array is attached and having threads with which the end of said longitudinally moveable rod connects so that a force applied to said button causes said longitudinally moveable rod to move along the threads of said sleeve thereby rotating said microabrader array.
7. The rotary device according to claim 4, further comprising means for retracting said microabrader array inside said abrader housing.
8. A method for delivering substance into skin via a microabrader device comprising the steps of:
positioning a microabrader device at a delivery site on the skin of a subject, said microabrader device comprising an abrader housing that surrounds an array of microprotrusions, wherein the abrader housing comprises at least one housing element selected from the group consisting of an upper housing, a lower housing, an inner housing, an outer housing, and combinations thereof, and wherein at least one of said at least one housing element is adapted for mechanical rotation of the microprotrusion array, and a support comprising a plurality of microprotrusions coupled to the support, said microprotrusions comprising at least one scraping edge and a length sufficient to disrupt the stratum corneum;
and rotating the microprotrusion array of said microabrader device against the skin at the delivery site with sufficient force for the microprotrusions to disrupt and penetrate the stratum corneum substantially without piercing the stratum corneum thereby allowing a substance to be delivered into the skin of the subject at the delivery site.
9. The method according to claim 8, wherein the abrader device comprises at least one rotation porting and at least one stationary portion and the rotating step is accomplished by manually rotating the rotating portion of said microabrader device at the delivery site on the skin of the subject.
10. The method according to claim 9, wherein the rotating step is accomplished by mechanically rotating the microabrader device.
