A tissue retraction device comprising:
- a cap having a proximal end, a distal end, and a lumen therethrough;
- and
- an extension member extending distally from the distal end of the cap;
- wherein the extension member is configured to engage a first engagement member such that the first engagement member is positioned at an angle with respect to a longitudinal axis of the cap lumen.

A tissue retraction system comprising:
- a first engagement member having a first end configured to engage tissue and a pair of gripping members proximal to the first end;
- and
- a grasping member with a pair of arms configured to grasp the first engagement member;
- wherein each one of the pair of arms is configured to interface with a respective one of the pair of gripping members.
1 more element
A method of retracting tissue comprising:
- back-loading a first working channel of an endoscope with a first grasping member extending out a distal end of the endoscope;
- back-loading a second working channel of the endoscope with a second grasping member extending out the distal end of the endoscope;
- loading a first engagement member having a first end configured to engage tissue and a second end, such that the first grasping member is disposed about the first end of the first engagement member;
- and
- loading a second engagement member having a first end configured to engage tissue and a second end, such that the second grasping member is disposed about the first end of the second engagement member.
