The robotic catheter system of claim 11, wherein the cassette is a disposable cassette having a use restriction element for functionally disabling the cassette from being used for a second procedure. 13. A cassette for use with a robotic catheter system, the cassette comprising: a housing;an rotational drive assembly coupled to the housing configured to impart rotational movement to a guide wire;a journal removably coupled to the housing and coupled to the rotational drive mechanism such that the rotational drive assembly is permitted to rotate relative to the journal; anda mechanical release structure releasably engaging the journal allowing the journal to be decoupled from the housing and permitting the rotational drive assembly to be removed from the housing without removing the guide wire from a patient;wherein the housing is removably coupled to a base a having a motor located therein, the motor operatively coupled to the rotational drive assembly. 14. The cassette of claim 13, wherein the mechanical release structure is moveable between a first position and a second position, and further wherein the mechanical release structure is moved to the second position to allow the rotational drive assembly to be decoupled from the housing. 15. The cassette of claim 13, wherein the rotational drive assembly includes a rotational drive mechanism to releasably engage and rotate the guide wire about the longitudinal axis of the guide wire. 16. The cassette of claim 15, wherein the mechanical release structure includes a projection that releasably engages a slot in the journal to couple the journal to the housing. 17. The cassette of claim 16, wherein the housing includes a base plate, and further wherein the journal includes a first portion and a second portion, the first portion positioned generally perpendicular to the second portion, the first portion is in contact with the base plate of the housing when the drive assembly is coupled to the housing, the slot positioned in the first portion. 18. The cassette of claim 13, wherein the rotational drive assembly is removable over the proximal end of the guide wire following decoupling from the housing by moving the rotational drive assembly away from the axial drive assembly. 19. A cassette for use with a robotic catheter system configured to couple to a base, the cassette comprising: a housing having a base plate;a first axial drive mechanism supported by the housing to releasably engage and drive a guide wire along a longitudinal axis of the guide wire;a rotational drive mechanism supported by the housing to rotate the guide wire about its longitudinal axis;a journal coupled to the rotational drive mechanism and removably coupled to the housing, the journal including a first portion, a second portion, and a slot positioned in the first portion, the first portion positioned generally perpendicular to the second portion, the first portion in contact with and generally parallel to the base plate of the housing when the rotational drive mechanism is coupled to the housing;a projection extending from the base plate that releasably engages the slot in the journal to couple the journal to the housing, anda button that causes the projection to disengage from the slot when the button is pressed allowing the journal to be decoupled from the housing allowing the rotational drive mechanism to be moved over the proximal end of the guide wire after the journal is decoupled from the housing;wherein the base includes motor operatively engaged with the rotational drive mechanism to rotate the guide wire.
