By a News Reporter-Staff News Editor at Obesity, Fitness & Wellness Week -- A patent application by the inventors KOBLISH, JOSEF V. (SUNNYVALE, CA), filed on July 24, 2012, was cleared for further review on November 22, 2012, according to news reporting originating from Washington, D.C., by NewsRx correspondents (see also Biotechnology Companies).

Patent serial number 557038 is assigned to Boston Scientific Scimed, Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Electrophysiology is the study of electrical impulses through the heart and is focused primarily on diagnosing and treating arrhythmias, conditions in which electrical impulses within the heart vary from the normal rate or rhythm of a heartbeat. The most common arrhythmia is atrial fibrillation (AF), which is characterized by rapid, disorganized contractions of the heart's upper chambers, the atria. AF results from abnormal electrical impulses propagating through aberrant myocardial tissue pathways, which leads to ineffective pumping of the blood through the heart, as well as other complications. Atria flutter (AFL), another type of arrhythmia, is characterized by a rapid beating of the atria. Unlike AF, AFL arises from a single electrical wave that circulates rapidly throughout the right side of the heart. Since this arrhythmia can arise from multiple electrical sites, effective treatment requires electrical isolation of the aberrant signal sites, thereby forcing the heart's normal conduction pathway to take over.

"The practice of interventional electrophysiology for treating arrhythmias, such as AF and AFL, generally involves inserting specialized catheters into a patient's vasculature and navigating the distal (or 'working') end of the catheters into the patient's heart chambers to identify' (or 'map') the locations of heart tissue that are a source of the arrhythmias. The mapping of the heart's electrical activity is typically accomplished using one or more pairs of electrodes, each pair spaced apart axially along the working end of the catheter. Following or in conjunction with the mapping procedure, the attending physician may use an ablation catheter to disable (or 'ablate') the tissue containing the aberrant signal(s) or signal pathway(s), thereby restoring the heart to its normal...
