Abstract

Described herein are devices and methods for treating tissue, comprising a catheter with a plurality of access sites and a plurality of sensors associated with the access sites. The catheter may be positioned along a tissue surface and the sensors may be used to identify a target site along the tissue surface using the plurality of sensors. Analysis of the tissue surface by the sensors is performed without requiring repositioning of the catheter. In some examples, the access sites of the catheter are side openings along a length of the catheter and the plurality of sensors are electrodes configured to measure electrophysiology parameters. In these examples, the catheter may comprise an internal lumen which permits a treatment device, such as an ablation catheter, to be slidably positioned at the desired target site without requiring displacement of the catheter. In other examples, the catheter may comprise a plurality of fixed ablation elements associated with the plurality of access sites.
