Declotting dialysis access grafts
without surgery or thrombolytics For chronic
hemodialysis patients.
The exclusive design of the Arrow-Trerotola PTD consists
of a 5Fr outer sheath with an inner cable connected to a
self-expanding fragmentation basket. Relatively simple
to use, the device is attached to a hand-held,
disposable rotator drive unit that spins at 3000 RPM.
Using the crossed-catheter technique
with two introducer sheaths, the catheter is placed into
the thrombosed graft. Once placed inside the clotted
graft, the basket Is deployed to fully expand and
conform to the graft wall. The rotator is then activated
and the spinning basket is withdrawn through the graft
to pulverize the thrombus.
