Reduce the risk
of nontarget embolization2,3.

The only reflux control microcatheter enabling flow directed embolization

Design Overview

Based on DRAKON® microcatheter technology,
SEQURE® optimizes flexibility 4, pushability and torqueability 5 for improved trackability 4,5,6.

Side slits

Specifically configured for each size of microcatheter eliminating vessel size limitation

Beads prevented to reflux

Reduces microspheres reflux and associated nontarget embolization

Contrast media fluid barrier

Radially filtered contrast media creates a fluid barrier around the microcatheter
