Abstract: Disclosed is a double balloon multiple lumen nasobiliary occlusion catheter that includes two inflatable balloons positioned about the distal end of the catheter. The catheter comprises several lumens which are used for inflating and deflating the balloons, venting bile, aspirating bile from the treatment site, and infusing and aspirating the dissolution solution. When inflated, the balloons occlude the lumen of the bile duct at two points thereby creating a sealed space between the balloons into which a treatment solution may be infused. Since this space is sealed from the remaining biliary tree, the treatment solution will find access to the gallbladder and stones via the cystic duct with the exclusion of bile from the gallbladder fundus, or it will be confined in high concentration around bile duct gallstones located between the inflated balloons. While the treatment solution is applied to the gallstones or to fragments of gallstones, bile is excluded from the treatment site.
