"We introduce a new class of tape-spring steerable needles capable of sharp turn s ranging from 15 to 150 degrees with a turn radius as low as 3mm, which minimiz es surrounding tissue damage. "In this work, we derive and experimentally validate a geometric model for our s teerable needle design. "We evaluate both manual and robotic steering of the needle along a Dubins path in 7 kPa and 13 kPa tissue phantoms, simulating our target clinical application in healthy and unhealthy liver tissue. "We conduct experiments to measure needle robustness to stiffness transitions be tween nonhomogeneous tissues.
