Systems and methods for percutaneous body lumen drainage

Abstract

The present disclosure relates generally to the field of devices and procedures for placement of a medical device between adjacent tissue structures. In particular, the present disclosure relates to systems and methods for percutaneous placement of a drainage stent between the gallbladder and gastric lumen (e.g., cholecystogastrostomy), or gallbladder and duodenum (cholecystoduodenostomy).

What is claimed is: 
     
         1 . A method of creating a passage between a first body lumen and a second body lumen for fluids to drain from the second body lumen to the first body lumen, said method comprising:
 extending a stent having a first end and a second end into a second body lumen;   extending the first end of the stent from the second body lumen to the first body lumen;   deploying the first end of the stent in the first body lumen; and   after deploying the first end of the stent, deploying the second end of the stent in the second body lumen.   
     
     
         2 . The method of  claim 1 , further comprising using a delivery system to deploy the first end of the stent in the first body lumen before deploying the second end of the stent in the second body lumen. 
     
     
         3 . The method of  claim 2 , further comprising:
 inserting the delivery system in a direction from the second body lumen to the first body lumen; and   withdrawing the delivery system in a direction from the first body lumen to the second body lumen.   
     
     
         4 . The method of  claim 1 , further comprising percutaneously accessing the second body lumen and inserting the stent percutaneously into the second body lumen. 
     
     
         5 . The method of  claim 4 , further comprising advancing the stent within the body from the second body lumen to the first body lumen. 
     
     
         6 . The method of  claim 1 , further comprising establishing a drainage passage from the second body lumen to the first body lumen. 
     
     
         7 . The method of  claim 1 , further comprising creating an open flow passage from the second body lumen to the first body lumen. 
     
     
         8 . The method of  claim 1 , further comprising:
 expanding the first end of the stent within the first body lumen to deploy the first end of the stent within the first body lumen; and   expanding the second end of the stent within the second body lumen to deploy the second end of the stent within the second body lumen.   
     
     
         9 . The method of  claim 8 , comprising expanding the first end of the stent within the first body lumen before expanding the second end of the stent within the second body lumen. 
     
     
         10 . The method of  claim 1 , wherein:
 deploying the first end of the stent comprises deploying the first end of the stent in a stomach; and   deploying the second end of the stent comprises deploying the second end of the stent in a gall bladder.   
     
     
         11 . A method of creating a passage between a first body lumen and a second body lumen, wherein fluid flows in the body in a direction from the second body lumen to the first body lumen, said method comprising:
 percutaneously inserting a stent having a first end and a second end into the second body lumen;   advancing the first end of the stent from the second body lumen into the first body lumen;   deploying the first end of the stent in the first body lumen; and   deploying the second end of the stent in the second body lumen to establish directional fluid flow from the second body lumen into the first body lumen.   
     
     
         12 . The method of  claim 11 , further comprising:
 expanding the first end of the stent within the first body lumen to deploy the first end of the stent within the first body lumen; and   expanding the second end of the stent within the second body lumen to deploy the second end of the stent within the second body lumen.   
     
     
         13 . The method of  claim 12 , further comprising using a delivery system to deploy the first end of the stent in the first body lumen before deploying the second end of the stent in the second body lumen. 
     
     
         14 . The method of  claim 13 , further comprising:
 inserting the delivery system in a direction from the second body lumen to the first body lumen; and   withdrawing the delivery system in a direction from the first body lumen to the second body lumen.   
     
     
         15 . The method of  claim 11 , wherein advancing the first end of the stent from the second body lumen into the first body lumen comprises advancing the first end of the stent within the body. 
     
     
         16 . A method of establishing a temporary flow passage between a first body lumen and a second body lumen, said method comprising:
 deploying a stent in a direction from the second body lumen to the first body lumen to deploy a first end of the stent in the first body lumen before deploying the second end of the stent in the second body lumen; and   withdrawing the stent in a direction from the second body lumen to the first body lumen.   
     
     
         17 . The method of  claim 16 , further comprising establishing a drainage passage from the second body lumen to the first body lumen. 
     
     
         18 . The method of  claim 16 , further comprising percutaneously inserting the stent into the second body passage and then advancing the stent within the body to the first body passage. 
     
     
         19 . The method of  claim 18 , further comprising removing the stent through a scope inserted in a natural body orifice. 
     
     
         20 . The method of  claim 16 , wherein:
 deploying the first end of the stent comprises deploying the first end of the stent in a stomach; and   deploying the second end of the stent comprises deploying the second end of the stent in a gall bladder.
