• CWS与其他颈动脉支架相比，具 有最小的支架网孔面积**
*Free Cell Area: 测量支架连接小杆周长间的平均面积 数值越小=支架网孔面积越小
**Testing performed on Carotid WALLSTENT Endoprosthesis 8mm x 21mm, Precise Pro RX 8mm x 40mm, RX ACCULINK 7-10mm x 40mm, Xact 7-9mm x 40mm. Bench test results may not necessarily be indicative of clinical performance. Test results shown are for models deemed most typically selected for placement in common carotid artery with a reference diameter of <8mm. Other models were also tested and yielded similar results.
