METHODS AND SYSTEMS FOR USE WITH A CARDIAC PROCEDURE TO REDUCE POST OPERATIVE ATRIAL FIBRILLATION

Abstract: one example provided a method for use with a cardiac procedure, including inserting a steerable delivery system into the body of a patient, the delivery system defining a lumen having an injection device disposed therein, and steering a distal end of the delivery system successively to each injection site of a plurality of cardiac injection sites, each injection site having a corresponding ganglionated plexi (gp) location. at each injection site, the method includes inserting a needle of the injection device into the injection site by extending the needle from a retracted position within the lumen to an extended position beyond the distal end, injecting a dosage volume of liquid treatment agent from the injection device into the injection site via the needle to treat the corresponding gp location to reduce potential occurrence of atrial fibrillation in response to the cardiac procedure, and retracting the needle into the lumen.
