Abstract
Gastrointestinal bypass devices are described. In one embodiment, a gastrointestinal bypass device may include an anchoring membrane configured to be attached to a wall of an esophagus with a tissue anchor placed through the anchoring membrane. The anchoring membrane may be configured to be pierced to allow the tissue anchor to be placed through the anchoring membrane.Methods for attaching a device to a tissue wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the device and the tissue wall, piercing the bulge from a first side of the anchoring membrane and a first side of the tissue wall, placing a second retention element of a tissue anchor on a second side of the tissue wall, and, placing a tension element of the tissue anchor through the anchoring membrane and the tissue wall. The tension element may be coupled to the second retention element. The method may further include placing a first retention element on the first side of the anchoring membrane. The first retention element may be coupled to the tension element.
