Double balloon-tipped catheter for the selective introduction of liquids into the gall bladder

摘要

The invention describes a special catheter for the selective introduction of liquid into the gall bladder which is advanced through the duodenum and the duodenal papilla into the common hepatic duct and whose front outlet opening is located between two devices of variable expansion. These prevent liquid from flowing into the biliary ducts of the liver and into the intestine, and they ensure selective filling of the gall bladder.
