SINGLE USE APPLICATOR CARTRIDGE FOR AN ELECTROKINETIC DELIVERY SYSTEM AND METHOD FOR SELF ADMINISTRATION OF MEDICAMENTS
First Claim
1. An applicator cartridge for use with a device for electrokinetically delivering a medicament to a treatment site, the cartridge comprising:
- an applicator head including an active electrode, and a conductive path extending between a pair of electrical contacts, wherein the electrical contacts electrically engage respective contacts on the device when the cartridge is inserted into the device;
a matrix support surface of said applicator head adjacent the active electrode;
a matrix attached to the matrix support surface and in contact with the active electrode, the matrix having an exposed surface adapted to be applied to the treatment site;
a medicament or a medicament and an electrically conductive carrier carried by said matrix;
a removable lid covering the exposed surface of the matrix and sealed to the applicator head, the lid is coupled to the applicator head, wherein removal of the lid breaks the conductive path.

13. A method of preventing reuse of an applicator cartridge for use with a device for electrokinetically delivering medicament to a treatment site on skin, the method comprising:
-
mounting a medicament pad in the applicator cartridge wherein the medicament pad is in electrical contact with an active electrode and has an exposed front surface to be applied to the treatment site; sealing a lid to the applicator cartridge to cover the front surface of the medicament pad; establishing a conductive path on the applicator cartridge that extends between contacts on the cartridge; inserting the applicator cartridge in the device and making electrical connections between the device and the cartridge; applying an electrical current from the device through the conductive path on the cartridge; if the electrical current passes through the conductive path, authorizing the applicator cartridge to deliver the medicament to the treatment site; removing the lid from the applicator cartridge; applying the exposed front surface to the treatment site and electrokinetically delivering the medicament through the treatment site, and by the removal of the lid, breaking the conductive path and disabling the device from delivering the medicament to the treatment site if the cartridge is reinserted into the device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method of preventing reuse of an applicator cartridge for use with a device for electrokinetically delivering medicament to a treatment site on skin, the method comprising:
-
mounting a medicament pad in the applicator cartridge wherein the medicament pad is in electrical contact with an active electrode and has an exposed front surface to be applied to the treatment site; including an electronically readable indicia on the applicator cartridge, wherein the indicia identifies the cartridge; inserting the applicator cartridge in the device and making electrical connections between the device and the active electrode and with the indicia; electronically reading the indicia with a processor or logic circuit in the device to determine if the cartridge has been previously used to deliver a medicament; applying the exposed front surface to the treatment site; if the determination is that the cartridge has not been previously used, applying electrical current from the device to the active electrode on the cartridge, and by the application of the electrical current to the active electrode, electrokinetically delivering the medicament to the treatment site. - View Dependent Claims (23)
