1. A tissue containment and removal system, comprising:
a tissue container including an opening, an interior volume, and a composite multiple layer structure that includes a watertight layer and a reinforcement member which is resistant to cutting or puncturing;
a tissue cutter including a distal end, a central lumen which extends from the distal end to a proximal portion of the tissue cutter and which is configured for pulling morcellated tissue therethrough and out of the proximal portion of the tissue cutter, and a cutter blade disposed on the distal end;
a cannula which is at least partially disposable through the opening and within the interior volume of the tissue container, the cannula including a central lumen in which the tissue cutter is configured to be disposed and positioned with an edge of the cutter blade extending distally of a distal end of the cannula and with the tissue container remaining open to the outside during morcellation of tissue by the cutter blade within the interior volume of the tissue container; and
at least one mechanical stop which is disposed on the tissue cutter and which is used to position the edge of the cutter blade distal of the distal tip of the cannula during morcellation by up to about 50.0 mm.
