Abstract
A gastro-intestinal tube which provides rigid support during stomal formation, while allowing tube removal by pulling from outside the abdominal wall. The tube has proximal and distal ends, a deformable internal bolster attached to the distal end, and a dissolvable support bolster placed around the tube proximal to the internal bolster. The support bolster is made of a dissolvable material, such that the bolster provides a high degree of securement to the gastro-intestinal tube during formation of the stoma, and dissolves to allow tube removal after the stoma has formed. In an alternate embodiment, the bolster has a coating of a medicating agent.
