EMERGE™

INTENDED USE/INDICATIONS FOR USE

The Emerge Over-The-Wire and Emerge Monorail PTCA Dilatation Catheters (1.20 mm balloon models) are indicated as pre-dilatation catheters in the stenotic portion of a coronary artery or bypass graft stenosis (≥70% stenosis).

The Emerge Over-The-Wire (balloon models 1.50-4.00 mm) and Emerge Monorail PTCA Dilatation Catheters (balloon models 1.50-5.00 mm) are indicated for the balloon catheter dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion. 

The Emerge Over-The-Wire (balloon models 2.00-4.00 mm) and Emerge Monorail PTCA Dilatation Catheters (balloon models 2.00-5.00 mm) are also indicated for the post-delivery expansion of balloon expandable stents (bare metal and drug-eluting).

CONTRAINDICATIONS

• Unprotected left main coronary artery.
• Coronary artery spasm in the absence of a significant stenosis.

WARNINGS

General Warnings

PTCA in patients who are not acceptable candidates for coronary artery bypass graft surgery requires careful consideration, including possible hemodynamic support during PTCA as treatment of this patient population carries special risk.

Use extreme caution and careful judgment in patients for whom anticoagulation is not indicated.

Use extreme caution and careful judgment in patients who have severe reaction to contrast agents that cannot be adequately pre-medicated.

PTCA should only be performed at hospitals where emergency coronary artery bypass graft surgery can be quickly performed in the event of a potentially injurious or life-threatening complication.

To reduce the potential for vessel damage, the inflated diameter of the balloon should approximate, or be less than, the diameter of the vessel just proximal and distal to the stenosis.

Catheter Handling

Use only the recommended balloon inflation medium. Never use air or any gaseous medium to inflate the balloon.

Catheter Placement and Removal

Do not exceed the balloon rated burst pressure.

PRECAUTIONS

The compatibility of the device has not been evaluated for the delivery of materials (e.g., drugs, alcohol, or stem cells) through the guidewire lumen, other than those required for normal use.

The balloon catheter should be used only by physicians experienced in the performance of percutaneous transluminal coronary angioplasty.

The safety and effectiveness of this PTCA balloon catheter for the treatment of in-stent restenosis (ISR) has not been established.
