Intravascular method and system for treating arrhythmia
First Claim
1. A method for locating and treating tissue of a patient'"'"'s heart exhibiting arrhythmia, comprising:
- a) locating tissue within the patient'"'"'s heart which is causing or is involved with the arrhythmia by detecting electrical activity by means of at least one intravascular device disposed within a coronary artery or cardiac vein of the patient;
b) determining which coronary artery feeds oxygenated blood to the located tissue causing or involved with the arrhythmia; and
c) delivering an occluding element to the coronary artery to occlude the artery blocking blood flow to the located tissue causing or involved with the arrhythmia and to thereby terminate the arrhythmia.

Abstract
A method and system for treating a patient'"'"'s heart exhibiting arrhythmia by first detecting electrical activity within the patient'"'"'s heart to determine the location of the arrhythmogenic site or conductive pathway causing the arrhythmia and then creating an infarct within the region of the patient'"'"'s heart where the arrhythmogenic site or the conductive pathway causing the arrhythmia is located by delivering an occluding element to a coronary artery which delivers oxygenated blood to said region of the patient'"'"'s heart. In one presently preferred embodiment the occluding element is a flaccid or limp coil which when disposed in a coronary arterial passageway forms a randomly shaped, intertwined mass which quickly forms thrombus within the coronary artery to block the passage of oxygenated blood therethrough. The flaccid coil may be delivered through an inner lumen of a catheter which has a distal portion extending within the coronary artery.

10. A method for locating and treating tissue of a patient'"'"'s heart exhibiting arrhythmia, comprising:
-
a) locating tissue of the patient'"'"'s heart which causes or is involved with the arrhythmia by means of at least one intravascular device disposed within a coronary artery or cardiac vein of the patient; b) determining which coronary artery or branch thereof feeds the tissue causing or involved with the arrhythmia; c) providing an intravascular catheter having proximal and distal ends and an inner lumen extending therein to a discharge port in the distal end; d) advancing the intravascular catheter into the patient'"'"'s coronary artery or branch thereof which feeds oxygenated blood to the tissue of the patient'"'"'s heart which causes or is involved with the arrhythmia; and e) directing an occluding element through the inner lumen of the intravascular catheter and depositing it in the coronary artery or branch thereof to block blood flow to the tissue causing or involved with the arrhythmia and to thereby terminate the arrhythmia. - View Dependent Claims (11, 12, 13, 14, 15)
