    摘要： Disclosed herein are systems and methods for attaching or maintaining the position of a therapeutic or diagnostic device in a body lumen, such as the GI tract without necessarily requiring any penetrating attachments through any body walls. The system can include at least two elements: a proximal orientation element and a distal support element. The proximal orientation element can be configured to reside at least partially within the esophageal lumen and the distal support element can be configured to reside in the stomach, such as along the greater curve of the stomach. An intragastric support system can have a first configuration in which the long axis of the proximal orientation element is substantially parallel and/or substantially coaxial with the long axis of the distal support element, and a second configuration in which the long axis of the proximal orientation element is not substantially coaxial with the long axis of the distal support element. The second configuration can thus advantageously retain the intragastric support system in place and prevent unwanted proximal migration of the distal support element into the esophagus or distal migration into the intestine.

    摘要： Disclosed herein are elongate flexible medical devices which are capable of axial elongation through a mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular body having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tubular body upon itself, causing an axial shortening of an overall length of the tubular device. An original length of the tubular device can be restored by coupling a pressurized media to the proximal end of the tubular device. If the distal end of the tubular device is temporarily restricted or closed, the pressurized media causes the distal end of the tubular device to travel distally until a full length of the tubular device has been restored.
