Abstract

A delivery system includes a rigid shaft, an imaging core, and an interventional core. The rigid delivery shaft has a proximal end, an angled distal tip, and an axial passage therethrough. The imaging core comprises an ultrasound imaging insert disposed within the axial passage. The imaging insert has an ultrasound array within a distal portion thereof, wherein the ultrasound array is tilted relative to a shaft axis. The interventional core comprises a curved ablation needle coupled to the rigid shaft. An angle of needle curvature may be inversely proportional to the ultrasound array tilt and tip angle.
