Carotid Stenting

A Filter Wire replaces the normal wire guide during balloon angi-

oplasty and stent delivery in the carotid system and traps emboli

dislodged during the process while allowing blood flow.

arotid angioplasty and stenting (CAS) is an acceptable alternative to

Ccarotid endarterectomy, especially in high risk patients for surgery.
While CAS has no risk of wound and cranial nerve complications, it car-

ries a risk of distal embolization and intraoperative stroke. Several devic-

es such as a filter wire has been designed to reduce intraoperative cere-
bral embolization
