Abstract
A stent/graft catheter delivery handle comprising a housing and a trigger pivotally connected to the housing on one end of the trigger. Squeezing the free end of the trigger towards the handle housing shifts a pawl, which is engaged with grooves on the outer surface of a stent/graft delivery catheter, longitudinally along the length of the catheter. Shifting of the pawl has the effect of retracting the sheath of the catheter relative to the plunger (inner lumen assembly) of the catheter and thus deploying a stent/graft stored in a proximal end of the catheter.
