Delivery Assist And Selective Catheters
Micrus® Ascent® Occlusion Balloon Catheter
Indications for Use
The Micrus Ascent Occlusion Balloon Catheters are intended for use in the blood vessels of the peripheral and neuro vasculature where temporary occlusion is desired and offers a vessel selective technique of temporary vascular occlusion which is useful in selectively stopping or controlling blood flow. The Micrus Ascent Occlusion Balloon Catheters are also intended to assist in the delivery of diagnostic agents such as contrast media, and therapeutic agents such as occlusion coils, into the peripheral and neuro vasculature.

Description
The Micrus Ascent Occlusion Balloon Catheters are coaxial dual lumen balloon catheters comprised of an inner guidewire lumen and a separate outer lumen to inflate and deflate the balloon. The balloon catheter is designed for use over any .014" or smaller guidewire. The balloon can be inflated and deflated independently of guidewire position. The balloon is equipped with a vent hole for easy preparation and removal of air from the balloon, and with two radiopaque markers for balloon positioning. Certain balloon catheter sizes may have a third radiopaque marker band 3 cm proximal to the tip to facilitate fluoroscopic visualization.
