Innovative Catheter Technology Hybrid Braid / Coil Design Unique braid/coil construction for the lowest profile of any 0.014” guidewire compatible catheter

Hybrid Braid/Coil Design • Tight pitch coil provides lumen integrity and bending flexibility • Proximal braid provides firmness and a torqueable catheter body for true 1:1 push/pull control Lubricious Hydrophilic Coating • Reduced friction for improved navigation in tortuous vessels • Exceptional durability for prolonged use Tight pitch inner coil Small OD, Large ID • 0.0165 inch ID microcatheter with a 1.6Fr distal shaft • Smallest OD catheter available that is compatible with coils and 0.014” guidewires Liquid Embolic Compatibility Proximal braid • Compatible with Onyx® Liquid Embolic System and nBCA

Balloon/Stent Assisted Coiling • Soft tip for exceptional tip painting and high sensitivity to coil deployment force • Lowest profile of any coil-compatible catheter (2.1Fr proximal/1.6Fr distal) • 0.0165” inner lumen supports all commonly used guidewire and coiling systems

Low profile offers maximum compatibility with dual catheter technique AVM Therapy • 156cm and 167cm length catheters compatible with 0.014” wires • Braided, torqueable shaft allows enhanced access to distal lesions • Soft, atraumatic distal tip • 700psi burst strength for added safety

Compatible with 0.014” guidewires and liquid embolic agents

AVF Therapy • Longest length of any coil-compatible catheter • Low, 1.6Fr profile distal shaft and soft tip for excellent navigation into small vessels • Allows the placement of coils and liquid embolic agents using one catheter, at lengths necessary to reach distal lesions

Soft tip aids in delivering both coils and liquid embolic agents Specifications
