PERCUSURGE
GUARDWIRE
This system provides temporary occlusion of the ICA and aspiration of particles
after CAS.
The device has three components: an exchange guide-wire, a micro-seal
adapter and a monorail aspiration catheter.
The distal segment of the 0.014" hollow nitinol wire is shape-adaptable,
radiopaque and steerable. Proximal to the floppy tip an aelastomeric
polyurethane occlusion balloon, with a crossing profile of 0.036", is attached
and it can be dilated from 3 to 6 mm according to the ICA diameter. Once the
wire is advanced beyond the target lesion, the balloon is dilated using the
handheld microseal adaptor and EZ Flator in order to occlude the ICA blood
flow. A contrast media injection is then performed to confirm the complete
occlusion of the blood flow within the ICA.
While the occlusion balloon remains inflated, the handheld system is removed
from the proximal end of the wire.
At the end of the procedure the Export aspiration catheter is inserted up to the
level of the distal occlusion balloon to aspirate the column of blood possibly
containing plaque debris. Two-three aspirations (15-45 ml of blood) are
suggested.
The aspiration catheter can then be removed and the occlusion balloon
deflated restoring the normal antegrade flow.
