Get the latest research information from NIH: You have reached the maximum number of saved studies (100). 1. The deployment catheter consists of two coaxial sheaths attached to a deployment handle. An FCSEMS with relatively high radial force (VIABIL stent and WallFlex stent) showed no migration, while the Niti-S series showed a high migration rate. During deployment there is no foreshortening and the stent cannot be reconstrained. The images to the right demonstrate the effects of low vs. high axial forces on biliary anatomy. Talk with your doctor and family members or friends about deciding to join a study. A single stent was enough to relieve malignant biliary obstruction in all patients. GORE, VIABIL, and designs are trademarks of W. L. Gore & Associates. Proprietary built-in anti-migration fins gently stabilize the device within the common bile duct, resisting the anatomical forces that could push the device out of place. Isayama H, Nakai Y, Toyokawa Y, et al. 2. removable up to months post-deployment in benign biliary-strictures The Wallflex TM Biliary TH fully covered stent When tension is applied to the retrieval loop using forceps, it causes the entire length and diameter of the stent to The aim of this study is to evaluate their safety and patency.

Biliary Endoprosthesis features the preferred combination of low Af and moderate Rf to minimize risk of migration, conforming naturally to the bile duct anatomy. Biliary Endoprosthesis maintains higher primary patency than the leading competitor at 3, 6 and 12 months post-deployment, when implanted to manage malignant biliary strictures. The covered stent was deployed first and then the bare stent was deployed telescopically, inside the lumen of the covered stent. The handle permits one-handed positioning and deployment via a trigger mechanism. Materials and methods Pre-procedural imaging with computed tomography (CT) or magnetic resonance imaging (MRI) was performed in order to exclude any metastatic deposits in the hepatic parenchyma, to assess the level of biliary tree dilatation to exclude … Biliary Endoprosthesis remains in the same location throughout deployment, eliminating the need to use a push-pull technique. On finding that the length of undeployed Viabil covered stents is shorter than the nominal length, we sought to determine the actual length of Viabil … A slight variation is the Viabil stent (Gore Medical, Flagstaff, Ariz), which is constrained by a thin filament tightly wound around the stent. deployment through the covered stent, stent patency and overall patient survival. (C) The stent is placed above the papilla. For general information, Learn About Clinical Studies. Successful deployment of the FCSEMS with antimigration system (VIABIL ® stent) All the patients underwent computerized tomography (CT) imaging prior to stent placement and at follow-up to assess pseudocyst resolution.

Stent deployment was technically successful in all 58 patients in the uncovered stent group and in all 58 patients in the covered stent group. (Clinical Trial), Multicenter Study of Removable GORE VIABIL® Biliary Endoprosthesis for Treatment of Benign Biliary Strictures, 18 Years and older (Adult, Older Adult), Successful treatment of benign stricture upon implant [ Time Frame: Upon implant ], Subject is diagnosed with treatable benign biliary stricture which necessitates the need for implantation of a biliary endoprosthesis, Subject is able to comply with study protocol and follow-up requirements, Written informed consent is obtained using the Investigational Review Board (IRB)/Ethics Committee (EC) approved consent form, Subject anatomy ruling out covered self expanding metal stent use (e.g. Significantly Lower Migration Rates than the Market Leaders1. The WallFlex Biliary RX Fully Covered Stent System RMV is the first and currently the only metal stent cleared in the U.S. for the treatment of benign biliary strictures secondary to chronic pancreatitis with indwell up to 12 months. The change in serum bilirubin at 2 weeks after stent placement can be used as a short-term evaluation of biliary drainage. Based on clinical publications, the GORE. Background and Aims: Limited data exist regarding fully‐covered, self‐expandable metal stents (CSEMS) with anchoring fins for the management of malignant distal biliary strictures. The stent patency period was calculated as the interval between stent insertion and its obstruction, or death, with a patent stent. WP111272. Covered self-expandable metal stents with an anti-migration system improve patency duration without increased complications compared with uncovered stents for distal biliary obstruction caused by pancreatic carcinoma: a randomized multicenter trial. Primary outcome measure is patency at each follow up visit. This most recent FDA clearance introduces exclusive Pull-Line deployment technology for the VIABIL stent. Viabil stent-grafts proved to be significantly superior to Wallstents for the palliation of malignant jaundice due to extrahepatic cholangiocarcinoma, with comparable cost … References * If deployed as instructed, the endoprosthesis will not appreciably foreshorten. Contrast injection is possible during stent deployment; however, the guidewire may have to be tem-porarily removed, depending on the delivery system. * In addition, the GORE® VIABIL® Biliary Endoprosthesis remains in the same location throughout deployment, eliminating the need to use a push-pull technique. Unique anti-migration technology aids in reducing the risk of reinterventions. 2013 Nov;108(11):1713-22. Patients were given intravenous antibiotics immediately before the procedure. Non-foreshortening* stent design and short wire delivery system provide optimal deployment positioning.

The GORE® VIABIL® Biliary Endoprosthesis offers the perfect balance of low Axial force (Af) and moderate Radial force (Rf), allowing natural conformance of the stent to the bile duct anatomy while maintaining industry-leading primary patency rates. Conmed Gore Viabil Metal Biliary Endoprosthesis Stents is a flexible fully covered, self expanding metal stent constructed from nitinol and an integrated ultra-thin, non-porous ePTFE (Expanded Polyetraflourethylene) or FEP Patency, or the ability for a stent to remain open and unoccluded, is a crucial characteristic of any Self-Expanding Metal Stent (SEMS). 1 Repeated endoscopic balloon dilation followed by insertion of multiple plastic stents (PS) has been shown to be highly effective for treatment of those strictures. 23 No significant difference in patency was observed as a result of the relatively high incidence of TI (9%) and migration (9%) in the CSEMS group.
