发明名称 Method and apparatus for augmentation of a sphincter
摘要 A system and method for delivering one or more implantable members, such as metal coils, via an introducer member, such as an endoscopic needle, into a space created within the submucosal layers of the LES to augment and bulk the sphincter to improve compliance in patients with gastroesophageal reflux disease. The implantable member comprises a first substantially straightened configuration when carried by the introducer member, whereby it assumes a more curvilinear or coiled configuration following deployment such that it expands against adjacent submucosal tissue, creating a bulge at the implantation site. In another embodiment, the implantable member can serve as an anchoring port for sutures or other elements introduced for gastroplication of the LES to create tissue folds that increase sphincter compliance. The implantable members may be configured to include an external portion that interconnects with an adjacent implantable member, thereby creating tension that also increases compliance of the LES.
