Product Details

CROSSBOSS Coronary CTO Crossing Catheter

Designed to quickly and safely deliver a guidewire via true lumen or subintimal pathways, CrossBoss gives you total access to coronary chronic total occlusions.

  • Atraumatic, rounded tip reduces risk of perforation
  • Hydrophilic coated, multi-wire coiled shaft provides precise turn-for-turn response
  • Fast-Spin torque device allows rapid rotation of the catheter to facilitate crossing

STINGRAY LP Coronary CTO Re-Entry System

Designed for reliability, safety, and predictability, STINGRAY LP allows the operator to accurately target and re-enter the true lumen from a subintimal position.

  • Self-orienting, flat balloon hugs the vessel, automatically positioning one exit port toward the true lumen
  • 180˚ opposed and offsetting exit ports enable selective guidewire re-entry
  •  Two radiopaque marker bands facilitate accurate placement and positioning
  • Hydrophilic coating on the balloon shaft ensures smooth device delivery 
  • 3.2F shaft diameter allows trapping in 7F guide and STRAW technique in 8F guide catheter
