  • Steerable needle
    Patent number: 7662128
    Abstract: The invention relates to a needle guidance system provided by a needle with a steerable tip. The needle has a cannula and a stylet. The stylet adjacent to its tip has a naturally curved portion. The stylet is movable in two degrees of freedom with respect to the cannula—axial translation and axial rotation with respect to the cannula axis. When extended, the stylet curves off-axis and provides cannula tip steering. Driving and/or steering systems may be provided to the orientation and relatively move the stylet.
