Abstract
A multiple-electrode catheter assembly includes a hollow catheter having an internal elongated channel and a flexible distal portion. A number of electrodes are spaced along the flexible distal portion. An inner element, slidingly engaged within the elongated channel, has a steering mechanism configured for selectively deflecting a steerable distal portion of the inner element. According to additional, or alternative, features, the inner element includes sliding contacts for forming electrical connections with the electrodes, and displaceable locating elements for determining the position of an electrode during operation. Also provided is a method for operating such a catheter.
