1. A tissue traction device comprising:
a self-supporting scaffold having a proximal terminal free end and a distal terminal free end, and shiftable between a delivery configuration within a delivery device configured to deliver said tissue traction device to target tissue within a patient, and a deployed configuration released from the delivery device with the proximal terminal free end and the distal terminal free end outside of and separated apart from and independent of the delivery device and completely within the patient when deployed from the delivery device, and expandable to be anchored with respect to tissue surrounding a region of the target tissue within the patient; and
a tissue traction element having a first free end directly coupled to said scaffold, and a second end free configured to be coupled to the region of target tissue via a separately formed tissue engagement member;
wherein said self-supporting scaffold is sized, shaped, structured, and configured to be anchored with respect to the region of target tissue as said tissue traction element exerts a traction force on tissue.
