Abstract: A tissue traction device having a target-tissue-engaging segment and more than one traction-tissue-engaging segment spaced apart from the target-tissue-engaging segment. The tissue traction device may have a peripheral section with at least one traction-tissue-engagement section therein, with at least one of the traction-tissue-engaging segments defined on such traction-tissue-engagement section. An additional traction-tissue-engagement segment may be defined within the peripheral section, optionally on an additional traction-tissue-engagement section, and/or within the at least one traction-tissue-engagement section. One or more traction-tissue-engagement segments within the peripheral section may be simultaneously and/or sequentially engaged with traction tissue to achieve varying force vectors of traction on the target tissue. A hanger may be provided on a tissue-engagement member or on the peripheral section of the tissue traction device to hold one or more of the traction-tissue-engaging segments extended from within the peripheral section of the tissue traction device to the traction tissue.
