  • Patent number: 7127279
    Abstract: 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.

  • Patent number: 6622035
    Abstract: An electrode for acquiring bioelectrical signals employs an array of spikes that penetrate the viable epidermis layer of the skin of a patient. The spikes may be conductive to provide the bioelectrical signal. Or, the spikes may extend through a conductive layer that provides the bioelectrical signal. The signal obtained from the patient may be amplified using an amplifier and battery circuit present on the electrode body. The electrode may be used with or without conductive paste or gel.

  • Patent number: 6560473
    Abstract: A disposal ECG Chest Electrode Template with built-in defibrillation electrodes has a location tab so that the template can be easily, quickly and correctly placed on the patient's chest during emergency situations. The template and its electrodes is transparent to x-ray allowing it to remain on the patient's chest throughout x-ray diagnosis and evaluation for so long as monitoring of the heart's electrical activity is required. The template carries ten electrodes, the standard six precardial electrodes and four limb electrodes. A pair of defibrillation electrodes are incorporated into the template are also correctly located on the patient when the template is placed on the chest by its location tab.

  • Publication number: 20030054024
    Abstract: A process for coating a perforated substrate with a gel (e.g. a polymerised acrylate hydrogel or a xerogel) without substantial occlusion of the perforations comprises (i) forming a layer of a liquid pregel mixture, comprising one or more monomers, on a web coated with a silicone, polyethylene, Teflon (R) or other coating having a surface energy less than the surface energy of the liquid pregel mixture. Preferably at least part of the curing takes place while the liquid pregel mixture is in contact with both the perforated substrate and the web. The process is especially applicable to the manufacture of attachment tabs for wigs and toupees, wound dressings, patches for transdermal drug delivery, therapeutic patches or biomedical electrodes.
