Abstract
An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. One or more spines have preformed configurations including at least a first portion with a first curvature and a second portion with a second curvature, and may include a linear portion. The linear portion may be between the first and second portions. The linear portion may be distal of the first and second portions. One or more spines have a narrower portion so that different portions of the spine can have different flexibility with a degree of independence in flexibility from adjacent portions.
