Abstract: Embodiments disclosed herein are directed to steerable devices configured to negotiate tortuous vascular pathways. The system can include a stylet having a shapeable portion formed of a shape-memory, super-elastic material such as Nitinol. The stylet can be placed within a catheter and can include a fiber-optic strain sensor (FOSS) system configured to determine a shape of the stylet.

Modifying the shape of the shapeable portion can modify an angle at which a distal tip of the stylet extends relative to the central longitudinal axis. A user can then rotate and advance the distal tip to negotiate tortuous vascular pathways. Similarly, modifying a flexibility of the shapeable portion can facilitate negotiating tortuous vascular pathways.
