Elongated steerable device with determined curvature

An elongated steerable device (10) for guiding a catheter or an endoscope comprising:

• an elongated flexible member (12) extending along a longitudinal axis (X), the flexible member (12) having a proximal extremity (12P) and a distal extremity (12D),
• at least one shape memory alloy wire (16) presenting at least one activable zone (17) and secured to the distal extremity (12D) of the elongated flexible member (12),
• an actuator (14) configured to activate the at least one shape memory alloy wire (16) from the proximal extremity (12P) of the elongated flexible member (12),
• wherein the activable zone (17) of the at least one shape memory alloy wire (16) is configured to present a resting configuration and an activated configuration, the activated configuration displaying at least one predetermined curvature (C1, C2),
• wherein the activable zone (17) of the at least one shape memory alloy wire (16) is configured to adopt the activated configuration when activated by the actuator (14), thus inducing the predetermined curvature (C1, C2) to the distal extremity (12D) of the elongated flexible member (12).
