Abstract
Systems and methods for separating pericardial tissue from the epicardium of the heart are disclosed. The apparatus includes a catheter comprising an elongated body, including a proximal end and a distal end and a lumen extending therebetween. The apparatus further comprises a needle carried at the distal end of the catheter. The needle includes a proximal end, a distal end, and a lumen extending between the proximal and distal ends, and is in fluid communication with the catheter lumen. The needle is of a length sufficient to penetrate myocardial tissue of the heart, from the endocardium to and through the epicardium. A coupling on the catheter is provided for communication with a fluid source, to facilitate flow of fluid through the catheter lumen and needle lumen. Fluid can thereby flow through the catheter and needle lumens to a location between the epicardium and pericardial tissue. Fluid flow to this location serves, among other things, to separate the pericardial tissue from the epicardium of the heart.
