Abstract

A method is described for shearing a tissue wall between a first cavity and an adjacent second cavity in a human or animal body. The tissue wall has a periphery forming an edge of an opening between the first cavity and the second cavity. A first member is placed into the first cavity, such that the first member is adjacent the wall. A second member is placed in the second cavity, proximate the first member. The first and second members have materials which magnetically attract one another. The first member and the second member are placed such that there is magnetic attraction between the first member and the second member through the wall and thereby compress an overlapping portion of the wall to create pressure necrosis. The first member and the second member are connected by a thread, wherein the thread extends over the edge of the opening.
