Figure 4: Connected Catheter Assembly with MDU
Rotatable Dispersion Wire Activation:
1.
Select the rotation speed using the speed selector on the MDU. (Figure 2, Item 8)
The four speed positions are labeled as L, M1, M2, and H, and represent approximately
the following:
a.
L – low, 2,000 RPM
b.
M1 – medium, 2,500 RPM
c.
M2 – medium high, 3,000 RPM
d.
H – high, 3,500 RPM
2.
Activate rotation of the Dispersion Wire by depressing the Trigger. (Figure 2, Item 10)
Catheter Sheath Marking Guide
Black
: A single ‘hash’ mark denotes 1 cm increment; and a double ‘hash’ mark denotes 10
cm increment.
White
: A single ‘hash’ mark denotes approximately 8 cm from the Dispersion Wire Tip
when the Dispersion Wire is unsheathed.
Procedural Steps
1.
Slowly withdraw the device through the treatment area while simultaneously infusing the
physician-specified agent.
•
Recommended technique:
o
Depress the syringe plunger with the thumb of the same hand that is holding the
MDU. (Figure 4).
o
A pull back rate of 1-2 mm/second is recommended.
Recommendation: While the Dispersion Wire is rotating, hold the MDU
with one hand, while using the other hand to securely grasp the catheter
proximal to the access site between two fingers and pullback ensuring
the catheter does not kink or become damaged.
o
Orient the Catheter/Wire to maintain a straight position and to avoid kinking or
creating an acute bend between the vascular access site and MDU.
