Stent/graft catheter handle
First Claim
1. A delivery catheter handle comprising a housing, a trigger pivotally attached to said housing, and a shifting means connected to said housing, a plunger of a delivery catheter is attached to the housing, forces applied to the trigger and the housing in generally opposing directions triggers the shifting means which shifts a sheath of the delivery catheter relative to the fixed plunger.

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.

- 2. A delivery catheter handle comprising a housing, a trigger having a top end and a bottom, and a shifting means connected to said housing, a plunger of a delivery catheter is attached to the housing, the top end of the trigger is pivotally connected to the housing, the shifting means is actuated by moving the bottom end of the trigger towards the housing, upon actuation the shifting means shifts a sheath of the delivery catheter, the shifting means is actuated when the trigger is squeezed towards the handle.
- 8. A delivery catheter handle comprising a housing, a trigger having a top end and a bottom end, and a shifting means connected to the housing, the top end of the trigger is pivotally attached to the housing, the shifting means is actuated by moving the bottom end of the trigger towards the housing, upon actuation the shifting means shifts a sheath of a delivery catheter towards the handle, the shifting means is actuated when the trigger is squeezed towards the handle, the shifting means comprises a slider having a top end and a bottom end, a pawl pivotally connected to the slider, and a slider rod having a proximal end and a distal end, the bottom end of the slider is pivotally attached to the trigger at a first point between the top end and the bottom end of the trigger, the pawl is pivotally connected to the slider between the first point and the top end of the slider, the slider has a slider lumen, a distal portion of the slider rod is slidingly disposed within said slider lumen, the proximal end of the slider rod is connected to the housing, the pawl engages grooves on an outer surface of a ratchet tube and is biased by a pawl spring connected to the slider against said outer surface, a slider spring is disposed about a proximal portion of the slider and biases the trigger away from the housing, the ratchet tube has a proximal end, a distal end, and a longitudinal ratchet tube slot, the distal end of the ratchet tube is attached to the sheath, a proximal portion of a plunger of the delivery catheter is disposed within the ratchet tube, a proximal end of the plunger is attached to a breakout, the breakout is removably attached to the housing and slides within the ratchet tube slot.
