A New Approach to Ultra-Thin Needle Steering: Development of an Ultra-Thin Omnidirectional Steerable Needle Without the Use of Axial Rotation

Flexible steerable needles can follow curved paths inside the human body, allowing to steer around objects, to adjust for mispunctures, and to reach multiple targets. However, the designs of existing ultra-thin (diameter < 1 mm) steerable needles require axial rotation of the needle to steer in 3D space causing needle twisting, which results...
