Aspiration and Directional Thrombectomy: Technology, Uses and Considerations

How aspiration catheter stroke works: an educational, technical overview covering the mechanism, applications, considerations, and INVAMED's related…

This article explains, in educational terms, aspiration catheter stroke — how the technology works and where it fits. Aneurysm techniques include packing the sac with detachable coils and redirecting flow across the neck with a densely braided flow diverter so the sac thromboses over time. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.

Background: Acute Ischemic Stroke and Intracranial Aneurysm Intervention

Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk. Aneurysm techniques include packing the sac with detachable coils and redirecting flow across the neck with a densely braided flow diverter so the sac thromboses over time. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients.

Aspiration and Directional Thrombectomy

Aspiration thrombectomy applies suction through a large-bore catheter advanced to the face of the clot to draw it out, sometimes as a first-line technique. Directional systems are designed to help engage clot in specific orientations within the vessel. INVAMED's Mantis Directional Thrombectomy System and AngioHAND Thrombus Removal System are positioned for aspiration-based clot removal in this setting. The choice of aspiration, a stent retriever, or a combined approach is made by the operator based on clot and vessel characteristics.

Design and Technical Notes

INVAMED's neurovascular portfolio spans clot retrieval, aspiration, aneurysm packing, embolization, and the access tools that reach the intracranial circulation. All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU. Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion.

Key Considerations

  • Speed to reperfusion is a central factor in stroke thrombectomy, which shapes device readiness and workflow in eligible patients.
  • Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen.
  • All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU.

Frequently Asked Questions

What is the regulatory status of these neurovascular devices?

Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.

What is the INVAMED stent retriever called?

INVAMED's stent retriever is the KinG Intracranial Revascularization Device, a self-expanding nitinol device with platinum markers for fluoroscopic visualization.

Who determines eligibility for thrombectomy?

The treating stroke team determines eligibility using imaging and current criteria; this article is educational and not medical advice.

About INVAMED

INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development. INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005.

Clinical and Technical Context

INVAMED's KinG stent retriever and its directional and aspiration thrombectomy systems support clot removal within the neurovascular line. Mechanical thrombectomy removes the clot with a catheter-based device, and it is used in selected patients alongside or after intravenous thrombolysis where indicated. INVAMED's Mantis Directional Thrombectomy System and AngioHAND Thrombus Removal System are positioned for aspiration-based clot removal in this setting. Aneurysm techniques include packing the sac with detachable coils and redirecting flow across the neck with a densely braided flow diverter so the sac thromboses over time. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. INVAMED's KinG Intracranial Revascularization Device is a self-expanding nitinol stent retriever with platinum markers at the proximal and distal ends of the basket for fluoroscopic visualization, intended for vessels including the internal carotid, middle and anterior cerebral, and basilar and vertebral arteries. Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen. INVAMED's neurovascular portfolio includes flow diverter stents for this parent-vessel reconstruction approach to selected aneurysms.
