A spine that may be used in the electrode assembly of an electrophysiologic catheter having controlled flexibility. The spine may have a flexible core that extends through a length of the spine, a polymeric cover and a plurality of electrodes, each having at least one lead, distributed longitudinally along the spine. An amount of material forming the spine may be adjusted longitudinally along the spine to compensate for changes in flexibility to the spine caused by varying numbers of electrode leads present at different relative longitudinal positions along the spine.

Electrode assembly having spines with controlled flexibility

An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. The spines have nonconductive covers that are reinforced with tensile members, e.g., wires or fibers, that extend (or have portions that extend) longitudinally so as to minimize any elongation of the covers and the microelectrodes carried thereon. The tensile members may also have a length greater than the length of the spines so the proximal portions extend proximally from the spines, through the catheter and at least into the control handle for actuation by an operator for deflecting and moving the spines, like 'fingers.'
