Transdermal drug delivery apparatus and methods
First Claim
1. A transdermal drug delivery apparatus configured to be engaged to skin of a user and supply fluid, the transdermal drug delivery apparatus comprising:
- a housing configured to be fastened to the user;
a microneedle assembly configured to be engaged against the skin, wherein the microneedle assembly is movably mounted to the housing to allow relative movement between the microneedle assembly and the housing;
a first force provider configured to provide a first force to force the microneedle assembly outwardly from the housing and against the skin;
a reservoir carried by the housing configured to contain the fluid and be in fluid communication with the microneedle assembly; and
a second force provider configured to provide a second force to cause at least some of the fluid to flow from the reservoir to the microneedle assembly.

Abstract
A transdermal drug delivery apparatus includes a housing for being fastened to a user, a microneedle assembly for being engaged against the skin of the user, a first force provider for providing a first force for forcing the microneedle assembly outwardly from the housing and against the skin, a reservoir movably carried by the housing for containing the fluid and for being in fluid communication with the microneedle assembly, and a second force provider for providing a second force for causing at least some of the fluid to flow from the reservoir to the microneedle assembly after the reservoir has moved into fluid communication with the microneedle assembly.

12. A transdermal drug delivery apparatus comprising:
-
a receptacle comprising a housing and a microneedle assembly mounted to the housing; a pushbutton movably mounted to the housing and configured to be pushed towards the microneedle assembly; a reservoir configured to contain fluid to be supplied to the microneedle assembly, wherein the reservoir is configured to move with the pushbutton relative to the housing along a path from an outer position to an inner position, in the outer position the reservoir is out of fluid communication with the microneedle assembly, and in the inner position the reservoir is in fluid communication with the microneedle assembly; a latching mechanism configured to open in response to the pushbutton being pushed towards the microneedle assembly; a pushing mechanism configured to release in response to the latching mechanism being opened; and a deformable membrane positioned between at least a portion of the pushing mechanism and the reservoir, wherein the pushing mechanism engages the deformable membrane to at least partially collapse the reservoir while the reservoir is in fluid communication with the microneedle assembly. - View Dependent Claims (13, 14, 15, 16)

17. A transdermal drug delivery apparatus configured to be engaged to skin of a user and supply fluid, the transdermal drug delivery apparatus comprising:
-
a housing configured to be fastened to the user; a microneedle assembly mounted to the housing and configured to allow relative movement between the microneedle assembly and the housing, comprising a first force provider positioned between the housing and the microneedle assembly configured to urge the microneedle assembly outwardly relative to the housing and against the skin; a reservoir mounted to the housing and configured to be moved relative to the housing from a first position in which the reservoir is out of fluid communication with the microneedle assembly to a second position in which the reservoir is in fluid communication with the microneedle assembly; and a second force provider configured to at least partially collapse the reservoir while the reservoir is in fluid communication with the microneedle assembly. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
