Multi-Band Rubber Band Ligation Device And Method Of Operation Thereof

Abstract

A rectal injection device and a method of operating the same. In one embodiment, the device includes: (1) a body having a handle, (2) a suction system associated with the body, (3) a trigger associated with the handle, (4) a pod coupled to the body via a neck and (5) multiple suction ports associated with the pod, each of the multiple suction ports configured to receive a ligation band thereabout, the suction system configured to provide a suction to the multiple suction ports to draw tissue thereinto, the pod configured to deploy the ligation bands upon activation of the trigger.

What is claimed is: 
     
         1 . A method of operating a rectal injection device, comprising:
 loading ligation bands about suction ports in a pod of said device;   inserting said pod into a rectum of a subject;   actuating a suction through said suction ports, said suction drawing tissue of said rectum into said suction ports; and   actuating a trigger of said device to cause said ligation bands to be deployed about the tissue.   
     
     
         2 . The method as recited in  claim 1  further comprising:
 releasing said trigger; and 
 withdrawing said pod from said rectum. 
 
     
     
         3 . The method as recited in  claim 1  further comprising placing syringes in cavities of said device. 
     
     
         4 . The method as recited in  claim 1  wherein said actuating comprises actuating a coupler of said device, said coupler coupled to syringes in air communication with said suction ports. 
     
     
         5 . The method as recited in  claim 1  wherein said loading comprises loading said ligation bands into having recesses in petals about said suction ports. 
     
     
         6 . The method as recited in  claim 5  wherein said actuating said trigger causes said petals to move to deploy said ligation bands. 
     
     
         7 . The method as recited in  claim 5  wherein said actuating said trigger causes said suction ports to move to deploy said ligation bands. 
     
     
         8 . The method as recited in  claim 5  wherein said device comprises three petals. 
     
     
         9 . The method as recited in  claim 1  wherein said device comprises three suction ports. 
     
     
         10 . The method as recited in  claim 1  further comprising employing a flange proximate said pod to discourage over-insertion of said pod into said rectum.
