Abstract: A transvascularly placed steerable microcatheter, further including internal steerability and the ability to articulate in a direction at right angles to its longitudinal axis at or near its distal end. The steerable microcatheter is generally fabricated from stainless steel, nitinol, or other metal and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable microcatheter can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature. The microcatheter is especially suited to robotic or powered control applications with user intervention or using artificial intelligence (AI).
