FAQs

MicroNet™ FAQs

 

What is the MicroNetTM?

The MicroNetTM is a bio-stable mesh woven from a single strand of 20 μm Polyethylene Terephthalate (PET).

Is there a drug on the stent or MicroNet?

No.

Can the MicroNet increase the chances of stent thrombosis?

No, the MicroNet only covers the outer surface of the stent system that is in contact with the arterial wall.

Does the MicroNet affect the deliverability of the system?

No, the sleeve is thin (20 μm) and flexible so it does not inhibit trackability or deployment.

 

MGuard™ & MGuard Prime™ FAQs

 

What are the MGuardTM and MGuard PrimeTM Embolic Protection Systems?

MGuardTM and MGuard PrimeTM Embolic Protection Systems are coronary balloon expandable stents wrapped in a Polyethylene Terephthalate MicroNetTM sleeve, creating a flexible mesh with low coverage area.

Can MGuard or MGuard Prime be used in cases of Acute Myocardial Infarction (AMI)?

MGuard and MGuard Prime are indicated for providing embolic protection in patients undergoing primary or rescue PCI for acute ST-segment elevation myocardial infarction (STEMI) or in patients with non ST-elevation acute coronary syndromes (unstable angina and non ST-segment elevation myocardial infarction).

Can MGuard or MGuard Prime be used in a cases of in-stent restenosis?

MGuard and MGuard Prime are indicated for providing embolic protection in cases of symptomatic coronary artery disease (CAD) due to a discrete de novo or restenotic lesion in a native coronary artery or a culprit lesion in a saphenous vein graft.

Can MGuard or MGuard Prime be used in cases where side branches are present?

Like any other coronary stent, operators should use caution when placing the MGuard or MGuard Prime when significant side branches are present.

What is the difference between MGuard and a covered stent?

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 is covered. Covered stents function quite differently than MGuard: they block flow into side branches and obstruct the artery’s natural healing process.

Is pre-dilatation necessary?

Operators should use standard practice. However, pre-dilation is recommend whenever there is potential difficulty in engaging the lesion.

Is post-dilatation necessary?

Operators should use standard practice. However, post-dilation is recommended whenever there is a situation of incomplete apposition after stent deployment.
