Tortuous anatomy presents a persistent challenge in catheter design, demanding advanced solutions for steerability, torque response, and deflection control. This tech brief brings together the knowledge from engineering experts in laser-cut hypotube technology, reinforced braided shafts, and integrated pull-wire mechanisms to share insights into the mechanical design and system integration of steerable catheters. Readers will gain a deeper understanding of the material, structural, and manufacturing decisions that impact catheter performance in complex anatomies.
