Microneedle arrays and methods for fabricating microneedle arrays
First Claim
1. A method for fabricating a microneedle array, the method comprising:
- providing a sheet blank of material having a first surface and a second surface opposite the first surface; and
stamping the sheet blank of material with a progression of dies to displace the material into a plurality of microneedles forming the microneedle array, wherein each microneedle extends away from and is solid from the first surface to a tip.

Abstract
Microneedle arrays, methods for fabricating microneedle arrays, medical devices, and methods for operating medical devices are provided. A method for fabricating a microneedle array includes providing a sheet blank of material. Further, the method includes stamping the sheet blank of material with a progression of dies, wherein the material is displaced into the microneedle array. A medical device includes a microneedle array, a base member having a first surface supporting the microneedle array and a second surface, and a flexible wall enclosing a chamber between the flexible wall and the second surface of the base member. The flexible wall is biased toward an extended configuration enclosing a first volume in the chamber. Further, the flexible wall is movable to a depressed configuration enclosing a second volume in the chamber less than the first volume.

11. A method for fabricating a deep drawn microneedle array, the method comprising the steps of:
-
providing a sheet blank of material; and drawing the sheet blank of material to form the microneedle array comprising microneedles extending up from an upper surface of a base member, wherein the base member has a thickness from the upper surface to a bottom surface of the base member, wherein the height of the microneedles above the upper surface of the base member is greater than the thickness of the base member, and wherein each microneedle is voidless from the bottom surface of base member to a tip. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
