Abstract
Methods and apparatus are provided for remotely controlling the bending of an elongated member by implementing energy responsive control over a member that is configured from two plastic materials of differing coefficients of thermal expansion. The disclosed methods and apparatus are particularly applicable for use in applications such as surgical catheterization where control of the member from a position relatively remote from the member is desired.
