1. A method to protect tissue in a patient's gastrointestinal tract during radiation therapy, the method comprising:
implanting an impermeable biodegradable device within a lumen of a first gastrointestinal tract portion, the impermeable biodegradable device formed as a single piece and comprising a continuous outer surface, a continuous tubular inner surface, a proximal end opening, and a second distal end opening, the proximal end opening extending into the lumen of the first gastrointestinal tract portion;
attaching a lumen of a second gastrointestinal tract portion to the lumen of the first gastrointestinal tract portion to form an anastomotic site, the distal end opening extending into the lumen of the second intestine gastrointestinal tract portion; and
securing the impermeable biodegradable device to the lumen of the first gastrointestinal tract portion utilizing an adhesive applied to an external portion of the impermeable biodegradable device such that the outer surface of the impermeable biodegradable device extends across the anastomotic site, the impermeable biodegradable device protecting tissue adjacent to the anastomotic site during radiation therapy.
