13.
With the device activated, slowly withdraw the rotating sinuous wire along the treatment site while infusing therapeutic agent
through the infusion port to break up the clot. Warning: A withdrawal rate of 1-2 cm/second is recommended when sharp
radii are encountered. When the sinuous wire reaches the tip of the venous sheath, release the switch to turn off the rotating
dispersion wire.
14.
Cover the device and remove it from the peripheral vasculature. Flush the catheter lumen with heparinized saline and manually
remove any accumulated fibrin from the sinuous wire.
15.
Aspirate the macerated clot via the sheath and discard the aspirate. Precaution: Continued unsuccessful aspiration may
collapse the sheath and vessel.
16.
Inject a small amount of contrast via the venous sheath to assess the degree of thrombus removal accomplished. Warning:
Avoid over-injection of contrast to minimize the risk of embolization. Treat the residual thrombus by repeating steps 11-
15 until acceptable thrombus removal is achieved.
17.
When the thrombus removal is complete, treat any underlying disease or stenosis per hospital protocol.
18.
Perform the final angiogram.
19.
Remove the sheaths from the peripheral vasculature.
20.
Achieve hemostasis at the puncture site(s) per hospital protocol.
