Cook Medical just unveiled a new .035 inch embolization coil for blocking or moderating blood flow through peripheral veins and arteries. The Retracta Detachable Embolization Coil is designed for more precise placement thanks to a radiopaque marker at the detachment point and a release system that allows to reconnect back to the coil to reposition it if necessary. From Cook’s announcement:
Based on the construction of Cook Medical’s Nester® coils, the Retracta coils use platinum technology to allow soft packing of the coil. Physicians can confirm placement accuracy under fluoroscopy by seeing the change in radiopacity at the detachment zone.
If the physician wishes, he/she can inject a contrast medium to confirm that the coil is correctly placed. Like the Nester coil, the Retracta can be used right out of the package.
