A novel guidewire system (ZigiWire Mode 3) enables successful neuroendovascular procedures by navigating complex aortic arches. This system overcomes challenges posed by aged, tortuous vasculature, improving patient suitability for critical interventions.

Area of Science:

  • Interventional Neurology
  • Vascular Surgery
  • Medical Device Technology

Background:

  • Navigating the aortic arch is crucial for neuroendovascular procedures.
  • Aging leads to aortic arch elongation, calcification, and reduced compliance, complicating access.
  • Traditional methods often fail in cases of complex or tortuous aortic anatomy.

Purpose of the Study:

  • To present the initial experience with the ZigiWire Mode 3 system for catheterizing complex aortic arches.
  • To evaluate the system's efficacy in accessing extracranial vessels for neuroendovascular interventions.

Main Methods:

  • The ZigiWire Mode 3 system involves the parallel advancement of three 0.014-inch guidewires.
  • This progressive system builds support-wire access for catheterization.

  • Diagnostic and guide catheters were advanced over the ZigiWire system.

    • Main Results:

    • The ZigiWire system facilitated successful catheterization through complex and tortuous aortic arches.
    • It provided stable distal access by preventing 'kickback' force common with single, larger guidewires.
    • The system enabled neuroendovascular procedures in patients previously deemed unsuitable due to vascular access challenges.

    Conclusions:

    • The ZigiWire Mode 3 system is a valuable tool for neuroendovascular procedures involving challenging aortic arch anatomy.
    • It offers a solution for difficult great-vessel access where conventional techniques have failed.
    • This technology expands treatment options for patients with complex vascular structures.
