Trial Summary

What is the purpose of this trial?The objective of this prospective, multicenter, randomized, controlled clinical trial is to demonstrate the superiority of the VBX Device for primary patency when compared to bare metal stenting in complex iliac occlusive disease.
Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you have a known intolerance to antithrombotic medications, you may not be able to participate.

Is the VBX Balloon Expandable Endoprosthesis generally safe for use in humans?

The VBX Balloon Expandable Endoprosthesis has been evaluated for safety in various studies, including its use in peripheral vessels and for aortic repairs. It has shown safety in these contexts, with studies assessing its use in complex procedures like branched endovascular aortic repair and iliac artery stenosis, indicating it is generally safe for human use.

What makes the VBX Balloon Expandable Endoprosthesis unique for treating Peripheral Arterial Disease?

The VBX Balloon Expandable Endoprosthesis is unique because it offers precise sizing and lower profile delivery compared to self-expanding stents, making it advantageous for treating peripheral arterial disease. Its balloon-expandable nature allows for better control and placement in the arteries, which can be crucial for effective treatment.

One-year results of a balloon expandable endoprosthesis as a bridging stent for branched endovascular aortic repair. [2023]This post-market multicenter registry aimed to evaluate the safety and performance of the GORE VIABAHN VBX balloon expandable endoprosthesis (VBX stent) implanted in peripheral vessels. In this subgroup analysis, we assessed the outcomes of the VBX stent as a bridging stent graft for visceral vessels during branched endovascular aortic repair at 1 year.
Use of the Gore Viabahn VBX balloon-expandable endoprosthesis in the congenital heart disease population. [2020]The Gore Viabahn VBX balloon-expandable endoprosthesis (W. L. Gore & Associates, Flagstaff, AZ) is a flexible covered stent that is FDA-approved for the treatment of iliac artery stenosis, including lesions at the aortic bifurcation. In this case series, we report the first use of the VBX covered stent in congenital heart disease, highlighting several of its unique advantages.
First/Preliminary Experience of Gore Viabahn Balloon-Expandable Endoprosthesis as Bridging Stent in Fenestrated and Branched Endovascular Aortic Repair. [2020]The aim of this study is to evaluate the preliminary outcomes of the Gore® Viabahn® balloon-expandable endoprosthesis (VBX) as bridging stent for fenestrated/branched aortic endograft.
Initial Experience With Viabahn VBX as the Bridging Stent Graft for Branched and Fenestrated Endovascular Aneurysm Repair. [2022]To evaluate the feasibility and safety of a novel balloon-expandable, heparin-bonded endoprosthesis (Viabahn VBX, W. L. Gore and Associates) when used as a bridging stent graft (BSG) with fenestrated and branched endovascular aneurysm repair (FB-EVAR). FB-EVAR and BSGs increase repair complexity with the potential for endoleak formation, stenosis, thrombosis, and graft migration. The mechanical construction of the Viabahn VBX and its antithrombogenic properties may provide an advantage for FB-EVAR over existing BSGs. The efficacy, safety, and clinical outcomes were assessed.
Long-Term Follow-up of Subjects With Iliac Occlusive Disease Treated With the Viabahn VBX Balloon-Expandable Endoprosthesis. [2023]This physician-initiated study provides 5-year (i.e., long-term) treatment durability data from 3 top recruitment sites that participated in the prospective, multicenter, nonrandomized, single-arm VBX FLEX clinical study (ClinicalTrials.gov identifier: NCT02080871). It evaluates the long-term treatment durability of the GORE VIABAHN VBX Balloon Expandable Endoprosthesis (VBX Stent-Graft) in the treatment of subjects with de novo or restenotic aortoiliac lesions.
Evaluation of the maintenance of the apical limit during instrumentation with hybrid equipment in rotary and reciprocating modes. [2017]The objective of the present study was to evaluate ex vivo the maintenance of the apical limit during instrumentation with the Root ZX (J Morita, Tokyo, Japan) and VDW Gold (VDW GbmH, Munich, Germany) hybrid devices in rotary and reciprocating modes and determine the possible function variations of different preparation levels (0.0 mm and -1.0 mm).
Assessment of Apical Extrusion during Root Canal Irrigation with the Novel GentleWave System in a Simulated Apical Environment. [2017]This study assessed apical extrusion during treatment with GentleWave (GW; Sonendo Inc, Laguna Hills, CA), a conventional open-ended 30-G needle (CN), or Endovac (EV; SybronEndo, Orange, CA) in root canals enlarged to different dimensions with and without apical constriction.
Outcomes of the Gore® Excluder® Iliac Branch Endoprosthesis Using Self Expanding or Balloon-Expandable Stent Grafts for the Internal Iliac Artery Component. [2023]Label="OBJECTIVE" NlmCategory="UNASSIGNED">The GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE; W.L. Gore & Associates, Flagstaff, Arizona) was developed to be used in combination with a self-expanding stent graft (SESG) for the internal iliac artery (IIA) bridging stent. Balloon-expandable stent grafts (BESGs) are an alternative for the IIA, offering advantages in sizing, device tracking, precision, and lower profile delivery. We compared the performance of SESG and BESG when used as the IIA bridging stent in patients undergoing EVAR with IBE.
Iliocaval reconstruction of chronically thrombosed cylindrical inferior vena cava filters with balloon expandable covered stent-grafts. [2021]The use of a Viabahn VBX endoprosthesis (W. L. Gore & Associates, Flagstaff, Ariz) to exclude chronically thrombosed inferior vena cava (IVC) filters refractory to exclusion with self-expanding stents was evaluated. The mean duration of TrapEase IVC (Cordis, Milpitas, Calif) implantation was 7.6 years (range, 2-11 years). Symptoms included leg pain, edema, color changes, and back pain. The mean Villalta score and venous clinical severity score were 17 (range, 13-23) and 13 (range, 11-15), respectively. Indirect ultrasound evidence of stent patency was demonstrated at a mean of 8 months after intervention. The mean Villalta score and venous clinical severity score had decreased by 13 and 10, respectively, at a mean of 9.5 months after intervention. Iliocaval reconstruction with Viabahn VBX balloon expandable stent-graft exclusion of chronically thrombosed TrapEase IVC filters is safe, with favorable short-term results.

Gutter Characteristics and Stent Compression of Self-Expanding vs Balloon-Expandable Chimney Grafts in Juxtarenal Aneurysm Models. [2020]Purpose: To assess in silicone juxtarenal aneurysm models the gutter characteristics and compression of different types of chimney graft (CG) configurations. Materials and Methods: Fifty-seven combinations of Excluder C3 or Conformable Excluder stent-grafts (23, 26, and 28.5 mm) were deployed in 2 silicone juxtarenal aneurysm models with 3 types of CGs: Viabahn self-expanding (VSE; 6 and 13 mm) or Viabahn balloon-expandable (VBX; 6, 10, and 12 mm) stent-grafts and Advanta V12 balloon-expandable stent-grafts (ABX; 6 and 12 mm). Setups were divided into 4 groups on the basis of increasing CG and main graft (MG) diameters. Two independent observers assessed gutter size and type as well as CG compression on computed tomography scans using postprocessing software. Results: In the smaller diameter combinations (6-mm CG and 23-, 26-, and 28.5-mm MGs), both VSE (p=0.006 to 0.050) and ABX (p=0.045 to 0.050) showed lower gutter areas and volumes compared with VBX. In turn, the VBX showed a nonsignificant tendency to decreased compression, especially compared to ABX. Use of the Excluder C3 showed a 6-fold increase in type A1 gutters (related to type Ia endoleak) as compared to the Conformable Excluder (p=0.018). Balloon-expandable stent-grafts (both ABX and VBX) showed a 3-fold increase in type A1 gutters in comparison with self-expanding stent-grafts (p=0.008). Conclusion: The current study suggests that use of the Conformable Excluder in combination with VSE chimney grafts is superior to the other tested CG/MG combinations in terms of gutter size, gutter type, and CG compression.
