Systems and related methods for tissue treatment

A method of treating tissue, the method comprising:

• coupling a grasping element to first tissue of a wall of a gastrointestinal tract, distal to a target tissue;
• coupling a ring to the wall of the gastrointestinal tract, proximal to the first tissue;
• relocating the first tissue to a location proximal to a second tissue, the target tissue being located between the first tissue and the second tissue;
• and
• coupling a second ring to the first ring, with tissue of the wall of the gastrointestinal tract between the first ring and the second ring.

A method of treating tissue, the method comprising:

• coupling a first ring to first tissue of a wall of a gastrointestinal tract, proximal to a target tissue;
• deploying a grasping element to the wall of the gastrointestinal tract, distal to the target tissue;
• relocating the target tissue proximally to a position proximal to the first ring so that second tissue overlies the first ring, wherein relocating the target tissue comprises relocating the grasping element from a position distal to the target tissue to a position proximal to the first ring;
• coupling a second ring to the first ring, with the second tissue between the first ring and the second ring;
• and
• cutting tissue proximal to the second tissue.
