Cross chronic venous occlusions

When a standard guidewire fails, channel through using the PowerWire® RF Guidewire

Overcome barriers to venous access

18-24%

CVOs Resistant to Standard techniques

18-24% of CVOs are resistant to standard crossing techniques.1-2 These refractory cases present a formidable challenge to endovascular interventionalists & prevent patients from receiving the treatment they need.1-2

Safely cross occlusions using RF Puncture Technology

RF Puncture Technology

Creates a small opening in tissue with minimal damage to surrounding area
High impedance High voltage Short RF delivery time
Low power Small active tip

How does RF puncture differ from RF ablation?

Learn how to cross complete
venous occlusions with the Sniper Technique

This four-part educational series, equips endovascular interventionalists with advanced techniques for successful venous recanalization. Review all facets of the Sniper Technique, from pre-procedural planning to post-operative care, to facilitate safe and effective recanalization of even the most complex central venous occlusions (CVOs) and iliac vein obstructions.

Tip Strength

Increasing tip strength corresponds to increasing stiffness

RF puncture creates a small opening in tissue with minimal surrounding tissue damage. RF Ablation creates a large lesion to destroy electrically conductive tissue. RF Ablation uses:
   Low impedance    Low voltage    Longer RF delivery time
   High power    Large active tip
