US 2012/0116528 A1 · TEMPORARY PROTECTIVE GASTROINTESTINAL DEVICE

Abstract

Disclosed is an intraluminal gastrointestinal (GI) device that is placed at the time of surgery to protect a freshly constructed GI anastomosis, GI staple-line, or the like. For the esophagus and stomach, the device covers the esophagus, stomach, and anastomosis/staple-line. For the pancreas or biliary duct, the device covers the biliary duct, pancreatic duct, and small bowel. For the colon and rectum, the device is a self expanding protective barrier that covers the anal canal, the anus, and the colon or rectum, approximately 18 cm proximal to the anus. These devices provide a waterproof barrier between the gastrointestinal content and the mucosa of the GI tract and the newly constructed anastomosis. Additionally, the design of the device is made to prevent migration within the gastrointestinal tract and facilitate removal of the device.

Dependent claims

An intraluminal protective device configured to be secured in a lumen of a patient, comprising:

a proximal tubular stent having opposed proximal and distal end portions and expandable from a collapsed state to an expanded state to exert a first radial force against an interior of the lumen;
a distal anchor;
and
a tubular lining spanning an axial gap spatially separating the proximal tubular stent from the distal anchor, the tubular lining configured to exert a second radial force on the interior of the lumen along an axial portion of the lumen corresponding to the axial gap, the second radial force being in a range between (a) substantially zero and (b) less than the first radial force, the tubular lining substantially impermeable to an alimentary tract content.
