摘要：
Disclosed is a prosthetic bulking device for implantation below the mucosa to treat gastroesophageal reflux disease. The bulking device comprises a flexible body which may have one or more attachment surfaces to allow tissue ingrowth from the adjacent tissue. The bulking device cooperates with residual lower esophageal sphincter (LES) function to increase LES closing pressure.
