Steerable medical device

A steerable medical device, comprising:

• an elongated member extending along a longitudinal axis and including a proximal end and a distal end and defining a lumen extending from the proximal end of the elongated member to the distal end of the elongated member, the elongated member adapted to be moved to a deflected position in which a deflectable portion of the elongated member is moved off of the longitudinal axis;
• a housing including a proximal end and a distal end, the housing fixedly coupled to the elongated member such that when the housing is moved in one rotational direction about the longitudinal axis the elongated member correspondingly rotates in the one rotational direction about the longitudinal axis;
• an actuator movably coupled to the housing;
• the actuator adapted to control movement of the deflectable portion of the elongated member;
• and
• an attachment member removably couplable to another medical device, the attachment member defining a proximal end and a distal end and being disposable over at least a portion of the elongated member, at least a portion of the attachment member slidably receivable by the housing, the housing and the elongated member being independently movable of the attachment member in a longitudinal direction when a position fastener disposed on the housing is unlocked.
