Publication number: 20190336268Abstract: Luminal devices are described. In one embodiment, a luminal device includes an esophageal stent and an anchoring membrane coupled to the esophageal stent. The anchoring membrane may be configured to be coupled to an esophageal wall 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 luminal device to the esophageal wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the luminal device and the esophageal wall, piercing the bulge from a first side of the anchoring membrane and a first side of the esophageal wall, placing a second retention element of a tissue anchor on a second side of the esophageal wall; and placing a tension element of the tissue anchor through the anchoring membrane and the esophageal wall. The tension element may be coupled to the second retention element.Type: ApplicationFiled: November 5, 2018Publication date: November 7, 2019Inventors: Jon ST.
