Publication number: 20040210158Abstract: The present invention relates to an improved method and apparatus for detecting and diagnosing disease states in a living organism by using a plurality of electrical impedance measurements. In particular, the invention provides for an improved electrode array for diagnosing the presence of a disease state in the human breast, and discloses a method of application of the array to the breast that ensures that the multiplicity of impedance measurements obtained from a first body part correspond as precisely and reproducibly as possible to the multiplicity of impedance measurements that are obtained from another, homologous, second body part. A number of diagnostic methods based on homologous electrical difference analysis are disclosed, including the calculation of a number of metrics used to indicate disease states by comparison with pre-established threshold values, and the construction of a number of graphical displays for indicating the location of disease to a body part sector.Type: ApplicationFiled: May 10, 2004Publication date: October 21, 2004Applicant: Z-TECH (CANADA) INC.Inventors: Leslie W.

Patent number: 5643255Abstract: A catheter, used e.g. for cardiac ablation, has a handle, a shaft, and a J-bendable distal end containing tip and ring electrodes. The tip electrode is axially rotatable and has insulated and uninsulated portions. As the tip electrode is rotated, the impedance between it and a reference level is observed. When the impedance reaches a maximum, this indicates that the uninsulated portion lies against the tissue and the insulated portion faces the bloodstream. An electrogram can be taken from the electrode, or an ablation current can then be applied to it. Short circuiting of the signal or current through the blood is thus reduced.Type: GrantFiled: December 12, 1994Date of Patent: July 1, 1997Assignee: Hicor, Inc.Inventor: Leslie W. Organ
