Abstract
An intravascular catheter includes an electrode carrying member. The catheter includes features visible in the fluoroscopic image that allow the practitioner to determine the radial position of the electrode carrying member within a blood vessel, and to confirm that the electrodes are positioned at the desired part of the vessel wall (e.g. against the posterior surface) and at the desired position along the length of the vessel, all without re-orienting the fluoroscope during the course of electrode positioning within the vascular. The features are shaped, formed in patterns, or possess other properties selected so that the appearance of the features on the fluoroscopic image differs depending on the rotational orientation of the electrodes. This can thus be used by the practitioner to determine whether, for example, an electrode carrying member having the features is positioned on the anterior or posterior wall of the blood vessel in which the array is positioned.
