Abstract

The disclosure provides a flexible, narrow medical device (such as a micro-catheter or a guidewire) that is controllably moved and steered through lumens of a body. The medical device may include an electrically-actuatable bendable portion at a distal end, which may be provided by a polymer electrolyte layer, electrodes distributed about the polymer electrolyte layer, and electrical conduits coupled to the electrodes, such that the polymer electrolyte layer deforms asymmetrically in response to an electrical signal through one or more conduits. The disclosure further includes a controller for moving the device into and out of bodily lumens and for applying the electrical signal for steering the device. The device further includes methods of preparing the polymer electrolyte layer in tubular shape.
