Solution

Crown rotational
speeds are variable
and will not stabilize

1. Immediately discontinue treatment, but leave the

OAS pump running.

2. Verify that saline is flowing. Verify VIPERSLIDE

Lubricant is present in the saline bag. See the
VIPERSLIDE Lubricant Instructions for Use for
information.

3. Verify that the saline tubing is properly connected to

the saline bag, that the saline tubing is routed
correctly through the OAS pump saline tubing guides,
and that the saline tubing is properly connected to
the OAD.

4. Verify that the crown advancer knob moves

smoothly.

5. Retract the crown proximal to the lesion. Using a

travel rate between 1 mm per second and 10 mm per
second, continue treatment on low speed.

6. If rotational speeds will not stabilize, replace the OAD

or guide wire.

The crown is not
moving one-to-one
with the crown
advancer knob

During start up in the vessel:
1.  Verify the Tuohy valve is not over-tightened.
2.  Verify the crown advancer knob moves smoothly.
3.  Retract the crown advancer knob until the crown

moves with the knob.

While spinning:
1. Immediately discontinue treatment, but leave the

OAS pump running.

2. Verify the Tuohy valve is not over-tightened.
3. Verify that the crown advancer knob moves

smoothly.

4. Retract the crown advancer knob until the crown

moves with the knob.

5. Verify that contrast media injections were not above

400 psi or occurred during crown spinning.

6. Engage and disengage the lesion using a travel rate

between 1 mm per second and 10 mm per second
while maintaining one-to-one crown to advancer knob
movement.

The crown stops
spinning during the
procedure

1. Immediately discontinue treatment, but leave the

OAS pump running.

2. Check to ensure that the OAS pump power cord is

connected to the back of the OAS pump and that the
OAD power cord is connected to the OAS pump.
