1. A tissue manipulation system for manipulating tissue in or adjacent to an intervertebral disc space, the system comprising: a deployment cannula having a proximal end portion, a distal end portion and at least one internal lumen; a guide member movable within said at least one internal lumen of the cannula and out of the distal end portion of the cannula to define a substantially continuous loop wherein the guide member extends from and returns into the at least one lumen; and at least one tissue manipulator having a leading end and a trailing end and comprising one or more of a blade including a cutting edge for cutting tissue, a tissue scraper including a scraping edge for scraping tissue and/or a tissue extractor including a tissue capturing structure for capturing and removing tissue from the intervertebral disc space, the at least one tissue manipulator being movable within said at least one internal lumen of the cannula, the at least one tissue manipulator having a passageway for receiving the guide member such that both the leading and trailing ends of the at least one tissue manipulator are advanceable over the guide member, first out of the distal end portion of the cannula and then around the substantially continuous loop defined by the guide member and returning again into the at least one lumen.
