Abstract

Tissue visualization devices having multi-segmented frame are described herein where such devices may utilize multiple expanding frame members coupled to a flexible deployment catheter shaft or rigid shaft. The multiple frame members may extend distally to collapse into a low-profile configuration and may further expand or open radially to create a working field between the frame members. Moreover, the distal ends of each frame member may be tapered such that the frame members may close tightly relative to one another forming an atraumatic end. Additionally, any number of therapeutic tools can also be passed through the catheter or shaft for performing any number of procedures on the tissue for identifying, locating, and/or treating tissue.
