1. A surgical system comprising:
one or more tissue effecting elements including a tip;
one or more device tags connected to the one or more tissue effecting elements, each of the one or more device tags having a spatial relationship and magnetic orientation with the tip of the one or more tissue effecting elements; and
an insertion mechanism including a device comprising:
plurality of markers, two or more of which are expandable rounded members that are positionable in a same lumen in an organ, the expandable rounded members being expandable from a stored state to an expanded state and when in the expanded state each of the expandable rounded members are configured to expand to move into contact with the lumen in the organ; and
wherein each of the expandable rounded members comprise a tissue tag, each of the tissue tags being magnetized or comprising a magnet;
wherein the expandable rounded members are configured to be located within and deployed from the insertion mechanism into the lumen in the organ at a predetermined location relative to the target tissue;
wherein the one or more tissue effecting elements are longitudinally movable relative to each of the expandable rounded members; and
wherein the tissue tags are removable from the lumen by contracting the expandable rounded members and withdrawing the expandable rounded members from the lumen;
wherein the one or more device tags present a magnetic field of common polarity respectively with each of the tissue tags of the device so that the one or more device tags provide an increase in tactile resistance to the tip of the one or more tissue effecting elements moving towards the tissue tags, the target tissue and the tissue tags are displaced as the one or more device tags are configured to be moved towards the target tissue and the tissue tags.
