The MicroNet is a mesh woven from a single strand of 20µ Polyethylene Terephthalate (PET), a non-biodegradable, bio-stable synthetic fiber widely used in a variety of industries from beverages to medical devices.
No, the MicroNet allows the endothelialization process to occur naturally.
No, the MicroNet only covers the outer surface of the stent system that is in contact with the arterial wall.
No, the sleeve is so thin (20µ) and flexible it does not inhibit trackability or deployment.
The main difference is in the percentage of surface area covered by the MicroNet, which is only about 20%. Whereas with covered stents, 100% of the surface area of the stent is covered. Covered stents function quite differently, for example, they block flow into side branches and obstruct the artery’s natural healing process.
The MicroNet’s balanced pore size allows excellent flow into branch vessels.
No.
No.
No, it is not necessary because CGuard’s SmartFit Taper Technology ensures it can conform to any anatomy.
No.
Yes, there is no reason CGuard could not be used in a DCP procedure.
Operators should use standard practice. However, pre-dilation is recommended when there is potential difficulty engaging the lesion. Use extreme caution when pre-dilating because it can cause embolization during a sometimes unprotected stage of the procedure. Many physicians safely utilize direct stenting with both CGuard and other carotid devices when conditions allow.
Operators should use standard practice. However, post-dilation should be carefully used only in cases where it is warranted, such as improving apposition or plaque compression.
The MicroNet traps potential emboli against the arterial wall before dislodgement.
Late embolization refers to embolization that occurs after the procedure, usually caused by plaque prolapsing through stent struts. The MicroNet prevents plaque from prolapsing.
CGuard’s method of protection is prevention. CGuard protects proactively rather than reactively, as most embolic protection systems currently function.
Operators should use standard practice. However, CGuard is an embolic prevention system. No build-up of emboli was observed on filters when it was measured during CARENET.
Operators should use standard practice. However, CGuard is an embolic prevention system. In some cases, proximal occlusion can be complementary with CGuard.
