1. An extended duration implantation apparatus for restricting the passage of food through a stomach comprising:

  • first and second cooperating jaws having opposed stomach wall engaging surface for clamping a stomach therebetween, the jaws being connected for co-planar pivotal movement with respect to each other;

    said opposed stomach wall engaging surfaces of the jaws defining at least one relatively open area for permitting the passage of food through the portion of the stomach received therein and at least one relatively closed area for preventing the passage of food through the portion of the stomach received therein, the relatively closed area of the opposed stomach wall engaging surfaces of the jaws further characterized by a plurality of matingly engagable contours for gripping a portion of the stomach therebetween whereby said jaws are prevented from movement relative to the stomach;

    means for preventing movement of the jaws relative to a stomach clamped therebetween;

    the first jaw being of a one-piece construction and having and an integral latching member extending from the unhinged end thereof towards the second jaw, a portion of the latching member including a locking mechanism;

    the second jaw having a receptacle for receiving the latching member of the first jaw and for engaging the locking mechanism of the latching member when the latching member is fully inserted therein; and

    wherein the latching member, when fully inserted in the receptacle of the second jaw, maintains a predetermined distance of separation between the stomach engaging surfaces of the jaws throughout the relatively closed area defined thereby sufficient to substantially prevent traumatizing stomach tissue secured between the jaws.
