Patent number: 6917825Abstract: A system for detecting and analyzing electrical activity in the anatomy of an organism underlying an electrode array provides signals corresponding to electrical activity adjacent each electrode. Such signals are correlated to the underlying anatomy of the organism and representative outputs presented through various types of output devices. Such outputs may include variations in coloration or other qualities in correspondence with representations of underlying anatomical structures. The system includes novel electrode structures (200, 224, and 284) and methods for producing and attaching electrode arrays (240 and 280) to the organism. The exemplary form of the invention is used in connection with the diagnosis of muscle activity in the lower lumbar regions of humans. Levels of muscle activity detected are analyzed by correlation with the muscular structures underlying the electrode array. Forms of the invention may be used in other applications.Type: GrantFiled: August 15, 2003Date of Patent: July 12, 2005Assignee: Advanced Imaging Systems, Inc.Inventors: Mark T. Finneran, Kathryn E.

Patent number: 6743223Abstract: The invention relates to a method for producing medical electrodes, in particular, neutral electrodes. According to the inventive method, a web-shaped laminate, consisting of a non-conductive intermediate support (C) and a conductive layer (A) is coated on the side of said conductive layer with an electrically conductive, adhesive gel (E). The laminate-gel combination is formed to a specific contour, preferably punched out, before being fixed to a carrier (H) by the side opposite to the gel (E). The conductive layer is applied to the web-shaped intermediate support (C) during the production of the laminate, preferably having been previously punched out, as panels which do not cover the entire web-shaped intermediate support (C).Type: GrantFiled: June 24, 2002Date of Patent: June 1, 2004Assignee: Leonhard Lang KGInventor: Burrhus Lang

Patent number: 6711427Abstract: A unitary electrode mounting and packaging system for roughening the skin of a patient and applying an electrocardiogram (ECG) monitoring electrode to the skin in a single step. A sheet of a thin plastic material is folded over itself to form a U-shaped carrier having an upper panel connected to a lower panel by the fold. The upper panel supports an electrode and an amount of an electrically conductive gel in a pocket that is covered by the electrode. The lower panel includes an abrasive or roughened material on the bottom surface of the lower panel opposite the electrode. To place the electrode on the skin, the carrier is positioned against the skin of a patient such that the roughened material contacts the skin and pressure is applied downwardly on the electrode. A tab connected to the lower panel then is grasped and pulled by an individual such that the roughened material abrades the skin beneath the carrier to clear the portion of the skin located beneath the electrode.Type: GrantFiled: February 13, 2002Date of Patent: March 23, 2004Assignee: Milwaukee Electronics CorporationInventor: Charles H.
