Abstract: 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.

Abstract: One or more tissue anchors may be delivered first without being coupled to an anchored device. An anchored device may be delivered second, and then coupled to the tissue anchors. This may enhance placement accuracy of tissue anchors, as well as facilitate delivery of tissue anchors. The tissue anchors include anchor couplings configured to be coupled to one or more device couplings of the anchored device.

Abstract: Improved assemblies, systems, and methods provide safeguarding against tissue injury during surgical procedures and/or identify nerve damage occurring prior to surgery and/or verify range of motion or attributes of muscle contraction during reconstructive surgery. A stimulation control device may incorporate a range of low and high intensity stimulation to provide a stimulation and evaluation of both nerves and muscles. A stimulation control device is removably coupled to a surgical device or is imbedded within the medical device to provide a stimulation and treatment medical device. A disposable hand held stimulation system includes an operative element extending from the housing, the housing includes an operative element adjustment portion and a visual indication to provide feedback or status to the user.
