Patent number: 7031769Abstract: An electrode assembly for use in an iontophoresis device for the transcutaneous administration of an active therapeutic species includes a base layer of conductive material which is consumed (oxidizes or reduces) preferentially to water, a first upper layer of sacrificial material coated on a first portion of the base layer wherein the sacrificial material is consumed preferentially to the conductive material of the base layer. A second upper layer of non-conducting material is coated on a second portion of the base layer, the second upper layer being spaced from the first upper layer, a narrow exposed linking area of the base layer material remaining therebetween. The exposed linking area of the base layer extends across the base layer. During operation of an associated iontophoresis device, the sacrificial material will be sequentially consumed; the first upper layer will be followed by the exposed linking area of the base layer which severs the base layer thereby breaking circuit continuity in the device.Type: GrantFiled: February 21, 2003Date of Patent: April 18, 2006Assignee: Birch Point Medical, Inc.Inventors: Carter R.

Patent number: 6745071Abstract: A reliable, self-contained iontophoretic drug delivery system is disclosed which enjoys a long stable shelf life and which is easy for the user to activate and employ. This system includes a wearable iontophoretic device that is prepackaged as a complete self-contained unit which includes the active species or drug to be administered and counter ions. The system includes a provision for isolating moisture sources from the electrodes and from the power source during storage and provides a simple, user-friendly mechanism to connect the drug to be administered and counter ion reservoirs to the electrodes and the device to the skin of a user in order to activate the device circuit. All elements of the device are contained in a single outer package.Type: GrantFiled: February 21, 2003Date of Patent: June 1, 2004Assignee: Birch Point Medical, Inc.Inventors: Carter R. Anderson, Russell L. Morris, Clayton J. Anderson, Lori A. Grace

Patent number: 6060319Abstract: A method and system for controlling the concentration of one or more gaseous species of interest in a fluid reference medium throughout a range of temperatures in which a temperature related, dominant independent source of the gaseous species of interest is used to control the partial pressure of one or more gaseous species of interest contained in the reference medium in a manner such that the concentration of the gaseous species of interest in the reference medium is controlled as a predetermined, normally generally linear, function of temperature, f(T), over the temperature range. The source of the one or more gaseous species of interest is a separate reservoir containing an amount of a formulated temperature sensitive source of the one or more gaseous species of interest. The reference medium and the reservoir are contained in separate liquid-tight, gas-permeable enclosures contained in a common substantially gas-tight enclosure.Type: GrantFiled: June 25, 1993Date of Patent: May 9, 2000Assignee: Diametrics Medical.

Patent number: 5231030Abstract: A multi-phase control and/or calibration system consists of a liquid phase containing an amount of dissolved oxygen (O.sub.2) in which the O.sub.2 partial pressure is made relatively temperature insensitive over an ambient temperature range of interest, and an amount of dissolved carbon dioxide (CO.sub.2) and one or more solute species that provide temperature stability with respect to the partial pressure of CO.sub.2 over the ambient temperature range of interest. The liquid phase is in equilibrium with a vapor phase and the system sealed with a storage atmosphere.Type: GrantFiled: February 18, 1992Date of Patent: July 27, 1993Assignee: Diametrics Medical, Inc.Inventors: David W.

Patent number: 5223433Abstract: A method and system for controlling the concentration of one or more gaseous species of interest in a sample medium throughout a range of temperatures in which a temperature related, time variable dominant independent source of the gaseous species of interest is used to control the partial pressure of one or more gaseous species of interest contained in the sample medium in a manner such that the concentration of the gaseous species of interest in the sample medium remains essentially the same over the temperature range. The source of the gaseous species of interest comprises a reservoir containing an amount of a temperature sensitive source of the gaseous species of interest. The sample and the reservoir are contained in separate fluid-tight, gas-permeable enclosures further confined by a common substantially gas-tight enclosure.Type: GrantFiled: December 13, 1991Date of Patent: June 29, 1993Assignee: Diametrics Medical Inc.Inventors: David W.
