Abstract: A steerable elongate medical device includes a composite shaft and a handle that is removably securable to the composite shaft. The composite shaft includes a first shaft component and a second shaft component. The composite shaft bends in a first direction when the first shaft component is heated above a transition temperature and bends in the first direction. The composite shaft bends in an opposing second direction when the second shaft component is heated above the transition temperature and bends in the second direction. The handle enables a user to selectively pass an electrical current through either of the first shaft component or the shaft component in order to electrically heat the selected shaft component.
