Embodiment Construction

[0024] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the various principles of the invention. It will be apparent to those skilled in the art, however, that not all of these details are always necessary to practice the invention. In this case, details of well-known circuits, control logic, and computer program instructions for conventional algorithms and processes have not been shown in detail in order not to unnecessarily obscure general concepts.

[0025] Turning now to the attached drawings, see first figure 1 , which is an illustration of a system 10 for detecting regions of abnormal electrical activity and performing an ablation procedure on a heart 12 of a living subject, in accordance with a disclosed embodiment of the present invention. The system includes a looped mapping catheter 14 which is inserted percutaneously through the patient's vasculature into the ventricles or vascular structures of t...

Abstract

The invention relates to a dual-purpose lasso catheter with irrigation. Cardiac catheters, including a lasso catheter, are provided for use in a system for electrical mapping of the heart has an array of raised, perforated electrodes, which are in fluid communication with an irrigating lumen. There are position sensors on a distal loop section and on a proximal base section of the catheter. The electrodes are sensing electrodes that may be adapted for pacing or ablation. The raised electrodes securely contact cardiac tissue, forming electrical connections having little resistance.

Description

technical field [0001] The present invention relates to cardiac mapping and ablation systems. More specifically, the present invention relates to loop mapping catheters for use in cardiac mapping and ablation systems. Background technique [0002] Arrhythmia such as atrial fibrillation occurs when areas of heart muscle tissue abnormally conduct electrical signals to adjacent tissue, disrupting the normal heart cycle and causing the heart rhythms to become asynchronous. Significant sources of unwanted signal are located in tissue regions along the left atrial pulmonary vein and the superior pulmonary vein. In this case, after unwanted signals are generated in the pulmonary veins or conducted through the pulmonary veins from other sources, these unwanted signals are conducted into the left atrium where they initiate or sustain the arrhythmia. [0003] Surgery to treat arrhythmias involves surgically disrupting the source of the signals that cause the arrhythmia and disruptin...
