Learn about Cook Medical’s Retracta® Embolization Coil at GEST 2017.

Detach with precision.

The Retracta coil is a detachable .035 inch diameter coil that’s fully retractable¹ and based on platinum Nester® coil technology.


Using a screw mechanism, the Retracta coil remains firmly attached to the delivery wire until you detach it, even if you push the detachment zone out of the catheter. Under fluoroscopy, the change in radiopacity at the detachment zone tells you where the coil is, allowing you to inject contrast to confirm that the coil is correctly placed. If you need to reposition the coil, pull the coil back into the catheter and adjust its position. When you’re satisfied with the placement, simply detach the coil.
