COMBINATION CARTRIDGE AND DEVICE FOR ELECTROKINETIC DELIVERY OF MEDICAMENT TO A TREATMENT SITE
First Claim
1. An electrokinetic delivery system for self-administration of a medicament to a treatment site on a human individual, the delivery system comprising:
- a cartridge applicator device shaped in part to conform to at least a portion of a finger of the individual and including a retainer for releasably securing the applicator device to the finger, a power source or coupling thereto, and a tactile electrode;
a cartridge including a first side for supporting a medicament, a second side, opposite to the first side, facing the applicator device when the cartridge is secured to the applicator device, and an active electrode accessible through the second side from the first side, wherein the active electrode is in electrical contact with said medicament and said power source when said cartridge is secured to the applicator device, whereby, upon application of the active electrode to the treatment site with a medicament interposed between said active electrode and the treatment site and completion of an electrical circuit through the active electrode, the medicament or a conductive carrier therefor, the treatment site, the individual'"'"'s body, the tactile electrode and the power source, said device causes an electrical current to flow for electrokinetically driving the medicament from the cartridge into the treatment site, and a locking element carried by one of the cartridge applicator device and the second side of the cartridge and engaged with a locking surface on another one of said device and the second side of the cartridge, said locking element is movable to release the securement between the cartridge applicator device and the cartridge enabling release of the cartridge from the device.

Abstract
A device for electrokinetic delivery of medicament to a treatment site includes a cartridge having an active electrode and a membrane overlying the active electrode and a medicament or a medicament and an electrically conductive carrier therefor, carried by the membrane in electrical contact with the electrode. The electrode opens through a surface of the cartridge remote from the membrane for connection with an electrical connector carried by the device. An locking element releasably couples the cartridge to the housing.

17. An electrokinetic delivery system for self-administration of a medicament to a treatment site on a human individual, said system comprising:
-
an applicator including a power source or coupling thereto, and a tactile electrode;
a cartridge having a first surface to receive a medicament matrix and a second surface facing the applicator when the cartridge is releasably secured to the applicator;
a locking element carried by one of the device and said second surface of the cartridge and engaged with a locking surface on another of said device and said second surface of the cartridge, said element being movable thereof to release the securement between the device and the cartridge enabling release of the cartridge from the device, said another of said device and said second surface of the cartridge includes an actuating surface co-operable with said element enabling a bias of said element to forcibly eject the cartridge from the device;
wherein said cartridge includes an active electrode extending through the second surface and to the matrix, said active electrode in electrical contact with said power source or coupling thereto when said cartridge is secured to the device whereby, upon application of the active electrode to the treatment site with a medicament interposed between said active electrode and the treatment site and completion of an electrical circuit through the active electrode, the medicament or a conductive carrier therefor, the treatment site, the individual'"'"'s body, the tactile electrode and the power source, said delivery system causes an electrical circuit to flow for electrokinetically driving the medicament from the cartridge into the treatment site. - View Dependent Claims (18, 19, 20)
