A system for placing an implant in the body includes an elongated member having at least one inner lumen extending from a proximal end portion of the member to an opening in a distal end portion of the member. At least one compressible implant is in the inner lumen of the member. The implant optionally includes anchor members projecting from its outer surface to limit migration of the implant in the body. Structure is provided to push the implant through the opening in the distal end portion of the member. The implant is placed between layers of body tissue to bulk the tissue. In one of the disclosed methods, the system is used to treat gastroesophageal reflux disease (GERD) by placing the implant between layers of body tissue at or near the gastroesophageal junction.
