tunneler sets are used for the precise subcutaneous
tunneling that is mandatory for hemodialysis blood
access grafts. Developed specifically for access
grafts, Kelly-Wick tunnelers are designed to minimize
trauma, allow accurate depth control and create
a uniform circular tract slightly smaller than
the outer diameter of the graft.

Each 6 mm diameter shaft has a knurled handle
that facilitates positive directional guidance
and depth control.
design of the interchangeable threaded tips
separates, rather than cuts tissue, thereby
minimizing tissue trauma.
tip features a suture hole to aid in securing
the graft and a machined waist to make a smooth
transition on to the shaft.
The tunneling technique used influences the
performance of vascular grafts, especially in
the early postoperative period.1
grafts should be placed without kinking or twisting.
grafts must be placed superficially enough to
allow easy cannulation, yet deep enough to prevent
skin erosion, especially in the diabetic patient.
use of clamps, forceps, surgeons fingers,
trocars and sheaths may cause excessive tissue
trauma, leading to perigraft swelling, seroma
or even hemorrhage.2 Any one of these
can compromise patency, delay healing and prevent
the safe early use of blood access grafts for
