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. Cholangiocarcinoma: Covered Viabil [GORE® VIABIL® Biliary Endoprosthesis] Stent Versus Uncovered Wallstents Krokidis M, Fanelli F, Orgera G, Bezzi M, Passariello R, Hatzidakis A, 2010 3 Talk with your doctor and family members or friends about deciding to join a study. Patency, or the ability for a stent to remain open and unoccluded, is a crucial characteristic of any Self-Expanding Metal Stent (SEMS). The images below demonstrate the effects of low vs. high axial forces on biliary anatomy. Listing a study does not mean it has been evaluated by the U.S. Federal Government. The stent patency period was calculated as the interval between stent insertion and its obstruction, or death, with a patent stent. 2.

The Bumpy-type stent was developed to prevent migration, and actually, migration did not occur in 32 patients in the first report [ 17 ]. Get the latest research information from NIH: You have reached the maximum number of saved studies (100). Non-foreshortening* stent design and short wire delivery system provide optimal deployment positioning. Learn about our Anti-Migration Assurance Program Endoscopic stent therapy is considered as first-line therapy for benign biliary strictures (BBS). At the end of the procedure, all patients were left with internal/external biliary drains for gravity drainage. (C) The stent is placed above the papilla. 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. Technical success was defined as the deployment of the The radiopacity of some metal stents is enhanced by incorpo Biliary Endoprosthesis are designed to enhance patency.

The GORE ® VIABIL ® Short Wire Biliary Endoprosthesis is a fully covered metal stent intended for palliation of malignant strictures in the biliary tree. Patients were given intravenous antibiotics immediately before the procedure. A removable ePTFE constraining sleeve is used to constrain and subsequently deploy the graft-lined region of the GORE VIATORR® TIPS Endoprosthesis. During deployment there is no foreshortening and the stent cannot be reconstrained. The ConMed Gore Viabil Biliary Endoprosthesis with Drainage Holes is a self expandable metal stent which is used to alleviate the symptoms caused by malignant biliary obstructions. Based on a number of clinical publications, GORE® VIABIL® Biliary Endoprosthesis demonstrates substantially lower migration rates than the competition. above hilar region), Treatment of stricture would require placement of a covered biliary endoprosthesis within a previously placed bare metal stent, The subject has malignant biliary disease, Participated in protocol involving investigational drug or device within 90 days prior to entry into this study. 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. Biliary Endoprosthesis features the preferred combination of low Af and moderate Rf to minimize risk of migration, conforming naturally to the bile duct anatomy. ** p<0.00000001, when compared to GORE® VIABIL® Biliary Endoprosthesis migration rates. Based on clinical publications, the GORE. Am J Gastroenterol. Gastrointestinal Endoscopy 2012;76(1):84-92.

Biliary Endoprosthesis offers the optimal 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. 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 … Isayama H, Mukai T, Itoi T, et al.

Malignant biliary stricture migration rate comparison1(Reported data is aggregated from 47 studies reported between 2002 and 2018). The change in serum bilirubin at 2 weeks after stent placement can be used as a short-term evaluation of biliary drainage. GORE® VIABIL® Biliary EndoprosthesisProven to Minimize the Risk of Reintervention1, OPTIMAL CONFORMANCETO  DUCTAL ANATOMY 2,3,4, GORE® VIABIL® Short WireBiliary Endoprosthesis, BOSTON SCIENTIFIC WALLFLEXBiliary RX Fully Covered Stent. Flagstaff, AZ; 2019. *  In addition, the GORE® VIABIL® 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 … 1. The GORE® VIABIL® Short Wire Biliary Endoprosthesis is a flexible endoprosthesis (stent) that is radially compressed and secured onto the distal end of a delivery catheter. U.S. Department of Health and Human Services, The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. This groundbreaking delivery system … Malignant biliary stricture migration rate comparison, (Reported data is aggregated from 47 studies reported between 2002 and 2018), Catalogs, IFUs, and Product Information Leaflets. Secondary study endpoints were the characterization of the type of stent dysfunction. 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 Stent Placement Accuracy The RX biliary delivery system is reconstrainable up to 80% of deployment to aid in repositioning*** and is designed to facilitate physician control. 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. Primary outcome measure is patency at each follow up visit. Gastrointestinal Endoscopy 2009;70(1):37-44. In the present analysis, the success rate of stent deployment did not vary, which is the main reason for the The moderate radial force, low axial force and durable, nonporous ePTFE/FEP liner of GORE. Based on a number of clinical publications. A slight variation is the Viabil stent (Gore Medical, Flagstaff, Ariz), which is constrained by a thin filament tightly wound around the stent. On the Cardiovascular & Interventional Radiology 2010;33(1):97-106. 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.  (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. Unique anti-migration technology aids in reducing the risk of reinterventions.
