Abstract
A catheter for diagnosing and ablating tissue is disclosed that has a stabilized spine electrode assembly. The stabilized spine electrode assembly has at least two spines secured to the catheter body at their proximal ends and at least one tether, secured between locations distal of the proximal ends of adjacent spines. The spines have a collapsed arrangement in which the spines are arranged generally along a longitudinal axis of the catheter body and an expanded arrangement in which at least a portion of each spine bows radially outwards from the longitudinal axis and the at least one tether exerts tension on the adjacent spines.
