US Patent:

6385488, May 7, 2002

Filed:

May 20, 1999

Appl. No.:

09/315768

Inventors:

Ronald J. Flower - Atlanta GA
Kenneth E. Garde - New Windsor NY
Steven D. Walter - Vernon NJ

Assignee:

Vyteris, Inc. - Fair Lawn NJ

International Classification:

A61N 130

US Classification:

604 20

Abstract:

Circuits are provided for increasing the reliability of an iontophoretic drug delivery system. Such circuits detect the failure of a crystal oscillator of the system, the failure of a voltage reference of the system, or the impending failure of a battery power source of the system.

Inventors:

STEVEN D. WALTER - VERNON NJ, US
KENNETH E. GARDE - NEW WINDSOR NY, US
RONALD J. FLOWER - LAWRENCEVILLE GA, US

Assignee:

DRUG DELIVERY TECHNOLOGIES, INC.

International Classification:

A61N001/30

US Classification:

604/020000, 604/021000

Abstract:

An iontophoretic system is provided, including a patch and a controller. The patch includes a plurality of electrodes electrically connectable to the controller and through which current is applied by the controller to the skin. The controller includes at least one current delivery profile, an input device, a control circuitry, and circuitry for generating the patch current. The current delivery profile is an element that can be changed independently of the other components of the controller. The control circuitry selects a current delivery profile using an input from the input device, and causes the current generating circuitry to generate and apply current to the patch electrodes in accordance with the read current delivery profile.
