Abstract: The invention provides for a steerable guidewire for insertion into a body cavity, characterized in that is comprises an elongated body defining a longitudinally-arranged lumen comprising i) a proximal end portion and ii) a distal end portion comprising a spatially reconfigurable portion and a tip; a pull wire located along said lumen and affixed to said distal end portion and to said proximal end; an actuation region located on said proximal end portion adapted to impart a tension force on the pull wire resulting in a compression force to the spatially reconfigurable region; and an intermediate region tubular element on said body located between said spatially reconfigurable portion and said proximal end.
