Indications for Use
This device is used to maintain patency of malignant esophageal strictures and / or to seal tracheoesophageal fistulas.
Device Story
The Evolution® Esophageal Stent System is a self-expanding nitinol wire stent provided pre-loaded in an introduction system. The system features a handle for desheathing (deployment) and resheathing (recapturing) the stent. The stent includes flanges at both ends to resist migration and a silicone membrane covering the body and partial flanges to prevent tissue ingrowth and seal fistulas. Radiopaque bands are present for fluoroscopic visualization, and a lasso loop allows for repositioning during initial placement. The device is used by trained healthcare professionals in a clinical setting to treat esophageal conditions. By maintaining patency or sealing fistulas, the stent improves patient quality of life and symptom management. The device is supplied sterile for single-use only.
Clinical Evidence
No clinical data. Evidence consists of non-clinical bench testing, including biocompatibility (cytotoxicity, irritation, sensitization, acute systemic toxicity, implantation), simulated use (deployment, repositioning, dimensional), corrosion, tensile strength, torque testing, shelf-life testing, and MR compatibility testing.
Technological Characteristics
Self-expanding nitinol wire stent with silicone membrane covering. Features flanges for migration resistance, radiopaque bands for fluoroscopy, and a lasso loop for repositioning. Supplied sterile via Ethylene oxide (EO). Single-use, prescription-only device.
Indications for Use
Indicated for patients with malignant esophageal strictures requiring patency maintenance or those with tracheoesophageal fistulas requiring sealing.

#### III. PREDICATE DEVICE
Primary Predicate: Evolution™ Esophageal Stent System, K080359 cleared May 09, 2008. Second Predicate: Evolution™ Esophageal Stent System - Fully Covered, K093619 cleared on June 17th, 2010.
The predicate devices detailed above have never been subject to a design related recall.
#### DEVICE DESCRIPTION IV.
The Evolution® Esophageal Stent System - Partially Covered consists of a self-expanding metal stent and a stent introduction system. The stent is provided pre-loaded in the introduction system. The handle allows for desheathing to deploy the stent and resheathing recapturing the stent during stent deployment.
The stent is woven from nitinol wire. The stent is formed with a flange at either end. The increased diameter of the stent at the stent ends helps provide resistance to migration. A silicone membrane applied to the stent covers the complete body of the stent along with part of both flanges. The covering is intended to reduce the risk of tissue ingrowth and provides a seal for tracheoesophageal fistulas. To aid in visibility under fluoroscopy there are four bands at either end of the stent. The stent has a lasso loop which can be used to reposition the stent during the initial placement procedure if desired. The device is supplied sterile, intended for single use only and is available for prescription use only. Use of this device is restricted to a trained healthcare professional.
#### V. INDICATIONS FOR USE
This device is used to maintain patency of malignant esophageal strictures and / or to seal tracheoesophageal fistulas.
