The invention provides for a steerable guidewire for insertion into a body cavity, characterized in that it comprises an elongated body (101) defining a longitudinally-arranged lumen (200) comprising i) a proximal end portion (100) and ii) a distal end portion (102) comprising a spatially reconfigurable portion (104) and a tip (105); a pull wire (106) located along said lumen (200) and affixed to said distal end portion (102) and to said proximal end (100); an actuation region (140) located on said proximal end portion (100) adapted to impart a tension force on the pull wire (106) resulting in a compression force to the spatially reconfigurable region (104); and an intermediate region tubular (108) element on said body (101) located between said spatially reconfigurable portion (104) and said proximal end (100).
