Method and device for the iontophoretic delivery of a drug
First Claim
1. A fluid reservoir for use with a drug delivery device, comprising:
- a sealed fluid chamber having a top surface and a bottom surface, and a cavity therebetween, the cavity being at least partially defined by at least one seal, wherein the cavity serves to house a fluid therewithin;
means for fracturing at least a portion of the at least one seal; and
means for controllably releasing a liquid out of the cavity, which liquid is positionable within the cavity, wherein the at least one seal comprises a first seal and a second seal, the second seal circumferentially surrounding the cavity, and the first seal concentric to and contained within the second seal, further defining the cavity between the first seal and the second seal.

Abstract
An iontophoretic drug delivery device storage apparatus and a method of using that device is disclosed. The device comprises a fluid reservoir, an electrode assembly and a tray apparatus. The fluid reservoir is capable of retaining a medicament and has a sealed fluid chamber defined by at least one seal. The seal includes a weaker region and a pinch-like configuration associated with that region such that application of pressure to the fluid reservoir breaks the weaker region of the seal, releasing the retained medicament. The electrode assembly comprises an active electrode, at least two passive electrodes a medicament carrying region, and a moat region around the medicament carrying region so that once fluid is delivered from the fluid reservoir to the electrode assembly the fluid is substantially retained in the medicament carrying means.

9. A method for releasing a fluid from a fluid reservoir, the method comprising the steps of:
-
depressing at least a portion of a sealed fluid chamber, wherein the fluid chamber includes a cavity at least partially defined by at least one seal, having a fluid therewithin;
fracturing at least a portion of the at least one seal; and
controllably releasing the fluid out of the cavity;
wherein the at least one seal comprises a first seal and a second seal, the second seal circumferentially surrounding the cavity, and the first seal concentric to and contained within the second seal, further defining the cavity between the first and the second seal, the step of fracturing at least one seal comprising the step of fracturing the first seal. - View Dependent Claims (10)
