Tissue retraction device and delivery system

A tissue retraction system, comprising:

• a tissue retraction device, wherein the tissue retraction device includes:
• a first engagement member having a first end and a second end;
• a second engagement member having a first end and a second end;
• a first tether disposed between the first and second engagement members;
• and
• a first alignment member having a first end, a second end, and a lumen extending therethrough;
• wherein the first tether extends within the lumen of the first alignment member;
• and
• a delivery catheter including a distal end, a proximal end, and a lumen extending therein;
• wherein the tissue retraction device is positioned within the lumen of the delivery catheter prior to being deployed in a body lumen;
• and
• wherein the first alignment member maintains the first tether in a substantially straight orientation within the delivery catheter during longitudinal advancement through the delivery catheter to prevent the first tether from folding upon itself.
