Continent Stomal Occlusion Device

Technology #2011-188

Ileostomy or colostomy are common permanent bowel procedures performed for inflammatory disease, trauma, or cancer. The development of an internal reservoir, obviating the need for an external appliance, has been hampered by the need for an interface between living tissue and the device. The invention disclosed herein is an adaptation of a floating ball valve. Within the bowel lumen lies a foreign body (ball or diaphragm) meant to occlude the outflow tract of the limb of bowel upon filling with stool. To discharge the luminal contents, a catheter is inserted into the outflow tract, disrupting the seal formed by the foreign body and the outflow tract, allowing luminal contents to be lavaged or otherwise aspirated.
