Devices and methods for gastrointestinal bypass
Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.
1. A method of treating a patient, the method comprising:
anchoring a gastrointestinal bypass device in an esophagus of the patient by delivering one or more tissue anchors through the gastrointestinal bypass device and through a wall of the esophagus at an attachment point, wherein the attachment point is approximately 0 mm to approximately 50 mm above a diaphragm of the patient.
2. A method of treating a patient, the method comprising:
anchoring a gastrointestinal bypass device in an esophagus of the patient by delivering one or more tissue anchors through the gastrointestinal bypass device and through a wall of the esophagus at an attachment point, wherein the attachment point is approximately 5 mm above to approximately 50 mm above a diaphragm of the patient.
3. A method of treating a patient, the method comprising:
anchoring a gastrointestinal bypass device in an esophagus of the patient by delivering one or more tissue anchors through the gastrointestinal bypass device and through a wall of the esophagus at an attachment point, wherein the attachment point is approximately 20 mm above to approximately 50 mm above a diaphragm of the patient.
