Aristotle wires for cannulating target vessels in paediatric neuro-interventional procedures: A case-control study.

Background: Paediatric neuro-interventional (PNI) procedures are markedly different to adult procedures and are more likely to be complicated by vasospasm. Traversing the complex tortuous anatomy in these fragile vessels requires both torque control and distal tip softness of the microwire. The Aristotle wires (Scientia Vascular Inc) are a new family of wires with design features offering both torque control and distal tip softness.
