One-year results confirm safety and efficacy across TASC A to D lesions, including complex anatomies
Barcelona, February 2026. iVascular announces the year results from the BARISTA Trial, the first clinical trial with Restorer Bare Metal Stent (BMS) a clinical study evaluating efficacy in the treatment of iliac artery lesions. The study provides strong evidence supporting the performance of Restorer across a broad spectrum of lesion complexity, from TASC A to TASC D.
The BARISTA Trial, led by Dr. Lieven Maene (Belgium), enrolled 200 patients, 34% of the study population presented with TASC C and D lesions, representing more complex anatomical scenarios and underscoring the robustness of the clinical evaluation.
At 1-year follow-up, the trial demonstrated excellent clinical outcomes:
- Freedom from Target Lesion Revascularization (fTLR): 96.4%
These results highlight the durability of the Restorer in maintaining vessel patency and reducing the need for repeat interventions.
Subgroup analysis further showed no statistically significant differences in outcomes between patients with TASC A&–B lesions and those with TASC C&–D lesions. This consistency across lesion complexity reinforces the reliability and versatility of Restorer in real-world clinical practice.
Procedural success was also supported by strong angiographic outcomes, with 98.5% of cases achieving residual stenosis below 30% following the intervention.
“The one-year results of the BARISTA Trial confirm that the use remains a safe and effective treatment option, even in more complex lesions,” commented Dr. Lieven Maene, Principal Investigator of the study. “The consistency of outcomes across TASC subgroups is particularly encouraging and demonstrates the reliability of this treatment approach.”
Overall, the BARISTA Trial reinforces the role a proven and durable strategy in iliac interventions. The results position Restorer as a dependable solution for physicians seeking predictable clinical performance across a wide range of lesion types.
About Restorer
Restorer is a bare metal stent designed for the treatment of iliac artery disease, combining radial and easy navigation and deliverability to support optimal vessel scaffolding. Its engineering focuses on procedural efficiency and reliable deployment, while promoting durable vessel patency across a broad range of lesion complexities.
