Abstract
Embodiments of the invention relate to methods for assessing and/or improving contact between an electrophysiology catheter and tissue, and catheters for performing the methods. One embodiment relates to a catheter comprising a braided conductive member coupled to the distal end of a shaft, wherein the braided conductive member comprises a plurality of pressure sensitive wires. Another embodiment relates to a catheter comprising a braided conductive member having a plurality of sectors and coupled to the distal end of a shaft, and a balloon assembly constructed and arranged to selectively apply distal pressure to one or more sectors of the braided conductive member.
