1. An endoluminal device, comprising:
a tubular member; and
a chamber extending beyond a distal end of the tubular member;
wherein the chamber is formed by a plurality of flexible elements comprising first and second expanding retractor elements and first and second lower retractor elements,
wherein the first and second expanding retractor elements are coupled to a retractor actuator disposed on a handle portion of the endoluminal device, the retractor actuator operable to move the first and second expanding retractor elements from a collapsed insertion position to an expanded position to contact target tissue in a body lumen to create a working space around the target tissue, and
wherein the first and second lower retractor elements are not coupled to the retractor actuator.
