A system including an implantable polymer for increasing the dimensions of layers of tissue. In one embodiment, the implantable polymer is delivered transorally using a scope and injection needle. The system allows for visualization and injection of polymer into the lower esophageal sphincter. Methods of treating gastroesophageal reflux disease includes insertion of the distal portion of the injection needle into the esophageal tissue and injection of a polymer liquid to enlarge tissue dimensions. The polymer can be injected at several sites to distribute localized pressures and attain better distribution of the tissue bulking effect.
