Abstract:
1. A guidewire for use in a medical procedure, which comprises: an elongate guide member dimensioned for insertion within a body vessel of a subject, the elongate guide member defining a longitudinal axis and having leading and trailing ends, the elongate guide member including an elongate body segment and a leading tip segment, the elongate body segment defining a longitudinal opening and the leading tip segment being adapted and dimensioned to articulate relative to the elongate body segment about a single axis of articulation; a control element extending through the longitudinal opening of the elongate body segment and operatively coupled to the leading tip segment, the control element longitudinally movable to cause corresponding articulating movement of the leading tip segment about the single axis of articulation; a first actuator coupled to the guide member for imparting at least rotational movement to the guide member; and a second actuator coupled to the control element, the second actuator adapted for sliding longitudinal movement in a direction generally parallel to the longitudinal axis and independently movable relative to the first actuator to cause corresponding movement to the control element and articulating movement of the leading tip segment about the single axis of articulation.
