Kidhibiti cha Mtiririko wa Tabaka Nyingi cha Stena Ndani ya Fuvu

A safu nyingi mtiririko-kuelekeza kujenga kwa aneurysms ya ndani ya fuvu, kuelekeza mtiririko wa damu mbali na kifuko cha aneurysm huku kikidumisha utiririshaji muhimu wa tawi.

Habari

The Stent Neurovascular Multilayer Flow Modulator ni a multi-layer, self-expandable implant designed to redirect blood flow across intracranial aneurysms or pseudoaneurysms (saccular, fusiform, or dissection). Constructed from nitinol braided wires, this flow-guided device harnesses hemodynamic modulation to promote stable aneurysm occlusion while preserving key vessel branches.

Multi-Layer Braided Nitinol Wires
  • Self-Expanding Implant: Adapts seamlessly to the host vessel, delivering gentle but consistent radial support.
  • Optimized Flow Modulation: Braided mesh design disperses hemodynamic forces, encouraging gradual aneurysm thrombosis without aggressively blocking perforator flow.
  • Excellent Visibility: Enhanced radiopacity simplifies device deployment and positioning under fluoroscopic guidance.
  • Continuous Vessel Coverage: The robust structure ensures stable wall apposition, helping minimize device migration or incomplete vessel coverage.
  • Size-Specific Microcatheters: Designed for use with 3.6F or 3.9F microcatheter (outer) and 2.3F internal microcatheter, ensuring sahihi navigation and stent delivery.
  • Pre-Loaded Configuration: The stent is supplied pre-loaded on its dedicated delivery system, streamlining procedural workflow and minimizing device manipulation.
  • Percutaneous Arterial Approach: Minimizes invasive exposure by allowing stent introduction through small-caliber femoral or radial arteries.
  • Adaptive Vessel Conformance: The device maintains uniform radial force along irregular or tortuous intracranial segments, preserving branch patency.
