Steerable medical device
First Claim
1. 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 to the distal end, the elongated member comprising a deflectable portion that includes the distal end and that is movable off of the longitudinal axis;
a steering mechanism adapted to control movement of the deflectable portion of the elongated member, at least a portion of the steering mechanism fixedly coupled to at least a portion of the elongated member such that rotation of the steering mechanism in one direction about the longitudinal axis correspondingly rotates the elongated member in that one direction about the longitudinal axis; and
an attachment member removably couplable to another medical device, the elongated member and steering mechanism movably coupled to the attachment member;
wherein the steering mechanism and the elongated member are configured to be independently movable of the attachment member.

Abstract
A steerable medical device is used to controllably introduce a guidewire or other medical instrument into a body of a patient and direct placement of the guidewire or other medical instrument in the body of the patient. The steerable medical device can include an elongated member, a steering mechanism, and an attachment member. The elongated member extends along a longitudinal axis and comprises a deflectable distal portion that is deflectable off of the longitudinal axis. The steering mechanism is adapted to control longitudinal and rotational movement of the elongated member and to control off-axis deflection of its deflectable portion. The attachment member is removably couplable to another medical device. The attachment member is moveably coupled to the steering mechanism and the elongated member.

18. 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; andan 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.
