Cartridge portion of transdermal drug delivery apparatus and methods
First Claim
1. A cartridge for supplying fluid in a transdermal drug delivery apparatus, the cartridge comprising:
- a body at least partially definingan interior for containing the fluid,a first cavity including a cylindrical section and a frustoconical section, the cylindrical section tapering to the frustoconical section,a second cavity,a passageway connected between the cylindrical section of the first cavity and the second cavity, andfirst and second openings to the interior of the body,wherein the first and second openings are respectively defined by opposite first and second ends of the body, wherein the first opening is contiguous with the first cavity, and the second opening is contiguous with the second cavity;
a self-sealing member at least partially closing the first opening; and
a movable member at least partially closing the second opening, wherein at least a portion of the movable member is configured for being urged into the interior of the body for increasing pressure within the interior of the body.

Abstract
A cartridge, which may be suitable for use as a portion of a transdermal drug delivery apparatus, may include a body at least partially defining an interior for containing fluid for being delivered by the transdermal drug delivery apparatus. The body may also at least partially define first and second openings to the interior of the body, wherein the first and second openings are respectively proximate opposite first and second ends of the body. The cartridge may also include a self-sealing member at least partially closing the first opening, and a movable member at least partially closing the second opening, wherein at least a portion of the movable member is for being urged into the interior of the body for increasing pressure within the interior of the body.

17. A cartridge for supplying fluid in a transdermal drug delivery apparatus, the cartridge comprising:
-
a body including a substantially concave wall, wherein the substantially concave wall at least partially defines an interior of the body for containing the fluid, the body at least partially defines a first cavity including a cylindrical section and a frustoconical section, the cylindrical section tapering to the frustoconical section, a second cavity, and a passageway connected between the cylindrical section of the first cavity and the second cavity, the body at least partially defines opposite first and second openings to the interior of the body, wherein the first opening is contiguous with the first cavity, and the second opening is contiguous with the second cavity, and the second opening is proximate the substantially concave wall; a self-sealing member at least partially closing the first opening; and a deformable member at least partially closing the second opening, wherein the deformable member is configured for being urged into the interior of the body and at least partially conforming to the concave wall for increasing pressure within the interior of the body. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
