The Medtronic InStent EsophaCoil Esophageal Stent System with Slow Release is self-expandable metal stent which is mounted on a delivery catheter. The stent is manufactured from a nickel titanium (Nitinol) material and is comprised of a center stenting section of adjacent coils and two flared ends which enhance fixation. The delivery catheter is manufactured from a thermoplastic material with a tapered end and flexible tip. The stent is wound in a reduced diameter configuration and held in place by a restraining means. The restraining means in connected to the "slow release" handle on the proximal end of the catheter.
