         15 . The device of  claim 14 , wherein said container of said treatment arms comprises a seal and a piston movable in said container to break said seal, movement of said piston causing said piston to break said seal and release said medicament to flow from said container and said applicator.  
     
     
         16 . The device of  claim 12 , wherein said applicator comprises a syringe, whereby said medicament will be injected into said canal wall.  
     
     
         17 . The device of  claim 12 , wherein said container is movable in said treatment arms between a retracted position and an extended position, and further comprising biasing structure for biasing said container toward said retracted position, said actuator being operable to move said container to said extended position.  
     
     
         18 . The device of  claim 1 , wherein said actuator comprises a plunger, said plunger having a reservoir for said medicament, and means for forcing said medicament from said reservoir and through said applicator.
