Larger microcatheters are being used with increasing frequency in routine neurovascular procedures. Navigating catheters safely and effectively to the target intracranial vessels can be a challenge when using conventional 0.014″ microwires. A new family of 0.024″ Aristotle 24 microwires (Scientia Vascular, West Valley City, UT) specifically designed for intracranial navigation were recently introduced. These microwires offer significant technical advantages over the standard 0.014″ microwires, including a reduced ledge gap, improved torquability and support, and overall safety. This video case series contains several illustrative cases to demonstrate the features of the novel Aristotle 24 microwire for use in endovascular neurointervention.
