NV Brain Training Access Test 2026 – 120+ Exam Questions & Expert Verified Answers – AXS Infinity, Catalyst & Synchro Guidewires

This document contains 120+ structured exam questions and expert-verified answers for the NV Brain Training Access Test 2026. It provides comprehensive coverage of neurovascular access systems, guidewire specifications, catheter compatibility, sheath sizing, and procedural applications in stroke, hemorrhage (HEM), and aspiration cases. The content is organized in a concise question-and-answer format designed to reinforce technical product knowledge and procedural decision-making. The material thoroughly reviews AXS Infinity LS and Infinity LS PLUS specifications, including ID/OD measurements, available lengths (70, 80, 90 cm), distal flex zone lengths (9.5 cm and 14.5 cm), hydrophilic coating lengths (10 cm), transition zones, and anatomical tracking capabilities (skull base vs. horizontal petrous). It also details AXS Catalyst 5, 6, and 7 distal access catheter specifications (inner/outer diameters, proximal/distal differences, transition zones, hydrophilic coating lengths), and procedure-specific use cases such as stroke intervention and aspiration thrombectomy. The guide provides in-depth explanation of AXS Lift specifications, radial compatibility requirements (6/7 Fr slender short sheath), transition zone length (15 cm), hydrophilic coating length (17.5 cm), and compatible short sheath accessories. Core vascular concepts such as torque (force × radius), nitinol shape memory properties, sheath sizing conventions (inner vs. outer diameter), and catheter working length calculations (working length + strain relief + hub) are also clearly outlined. Extensive coverage is given to Synchro 2 and Synchro Select guidewire series, including .014-inch diameter specifications, 200 cm and 215 cm lengths for access, 300 cm lengths for exchange, distal support profiles (Soft, Standard, Support), platinum-tungsten coil lengths, microcatheter compatibility (.016”), reduced tip shape percentage (28%), and enhanced tip retention through specific nitinol cut patterns. Clinical access statistics (femoral vs. radial by HEM and AIS case types), flush requirements (heparin saline), access wire size (.035 with 18-gauge needle), and diagnostic catheter shapes (Berenstein, Vert, VTK, Simmons) are also included.
