SEALANT Study:

LVIS™ Evo™ and HydroCoil® Embolic System for Intracranial Aneurysm Treatment
LVIS™ Evo™ and HydroCoil® Embolic System

"SEALANT provides robust prospective evidence supporting the safety and effectiveness of SAC using LVIS™ Evo™ and HES coils, in a population of predominantly wide-necked aneurysms."

Design

Single arm prospective

Scope

Patients ≥ 18 y.o. with an unruptured or ruptured (> 30 days since occurrence) IC aneurysm requiring treatent with Stent assisted coiling with LVIS EVO and HES coils (90% in lenght).

Purpose

Safety and efficacy evaluation of stent-assisted coiling procedures using LVIS™ Evo™ device with HES coils based on the morbidity and mortality rates and complete occlusion/ occlusion stability within 12 +/-6months after treatment

Endpoints

Aneurysm complete occlusion based on Raymond–Roy occlusion classification (RROC) at the 12 ± 6-month follow-up evaluated by an independent Core laboratory using digital subtraction angiograms (DSA).

Efficacy results

  • Successful implantation of LVIS EVO: 99.5%

  • Complete occlusion rate at 12±6 months using DSA: 82.1% (PP)

  • Retreatment at 12±6 months: 0.0%

Safety results

  • Primary safety endpoint: 2.4%

  • Major ipsilateral stroke or neurological death related to study devices or procedure: 1.0%

  • Intra procedural subarachnoid haemorrhage: 1.5%

  • In-stent thromboembolic complication:1.5%

  • Thromboembolic complication distal or proximal to the stent: 0.5%
