Endoluminal device with retractor system

An endoluminal device, comprising:

• a first tubular member;
• a second tubular member extending through a lumen of the first tubular member;
• wherein a distal end of the second tubular member is attached to a distal end of the first tubular member, and a proximal end of the first tubular member is attached to a proximal end of the second tubular member, and wherein a central portion of the second tubular member disposed between the proximal and distal end of the first tubular member is substantially floating within the lumen of the first tubular member;
• a chamber extending beyond a distal end of the first 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, and the first and second lower retractor elements are not coupled to the retractor actuator, the retractor actuator operable to move the first and second expanding retractor elements from a collapsed insertion position to an expanded position.
