1. A method of shearing a tissue wall between a first cavity and an adjacent second cavity in a human or animal body, the method comprising:
placing a first member into the first cavity, such that the first member is adjacent the tissue wall;
placing a second member in the second cavity and proximate the first member; and
positioning a thread connecting the first member and the second member such that the thread forms a loop from the first member to the second member around a peripheral edge of the tissue wall without passing through the tissue wall;
wherein the first member and the second member comprise materials which magnetically attract one another; and
wherein the first member and the second member are placed such that magnetic attraction between the first member and the second member through the tissue wall compresses an overlapping portion of the tissue wall to create pressure necrosis.
