(54) TISSUE RETRACTION DEVICE AND DELIVERY SYSTEM


(57) The present invention relates to a tissue retraction delivery system (1910), including a tissue retraction device (1922) positioned within a delivery catheter (1926), a support catheter (1970) with a distal end (1974), and a pull-back member (1972) extending within a lumen (1977) of the support catheter (1970), wherein the tissue retraction device (1922) includes a tissue engagement member (1952), wherein the tissue engagement member (1952) comprises jaws and an actuation portion (1953), wherein the support catheter (1970) and/or the pull-back member (1972) are configured to be manipulated such that pulling the actuation portion (1953) against the distal end (1974) of the support catheter (1970) shifts the jaws of the tissue engagement member (1922) from a closed position to an open position.
