Abstract
A robotic catheter system is provided. The robotic catheter system includes a housing and a drive assembly coupled to the housing. The drive assembly is configured to impart movement to a catheter device. The catheter system includes a release structure permitting the drive assembly to be decoupled and removed from the housing without removing the catheter device from a patient.

14. A cassette for use with a robotic catheter system, the cassette comprising:
-
a housing; an axial drive assembly supported by the housing configured to impart axial movement to a guide wire; a rotational drive assembly coupled to the housing configured to impart rotational movement to the 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; and a 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. - View Dependent Claims (15, 16, 17, 18, 19)

20. 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 second axial drive mechanism supported by the housing to releasably engage and drive a working catheter along a longitudinal axis of the working catheter; 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, and a 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.
