1. A robotic catheter and sheath device cartridge assembly comprising:

  • a first catheter element of a catheter cartridge configured to be linearly driven by a second catheter element of a catheter manipulation base, wherein the first catheter element and the second catheter element are not rigidly connected and are configured for engagement with and disengagement from each other, at least one of the first and second catheter elements slidably engageable with at least one of the catheter manipulation base and the catheter cartridge, respectively, the catheter manipulation base configured for releasable connection to the catheter cartridge and configured to be linearly movable along a longitudinal axis of the catheter manipulation base, at least one of the first and second catheter elements being a first driven element and being linearly driveable in a first predetermined direction for operating the catheter cartridge, the first catheter element of the catheter cartridge being operably engaged with a first tensionable deflection member for laterally deflecting a distal end of a catheter component of the catheter cartridge having the first tensionable deflection member engaged thereto when the first driven element is linearly driven in the first predetermined direction; and

    a first sheath element of a sheath cartridge configured to be linearly driven by a second sheath element of a sheath manipulation base, wherein the first sheath element and the second sheath element are not rigidly connected and are configured for engagement with and disengagement from each other, at least one of the first and second sheath elements slidably engageable with at least one of the sheath manipulation base and the sheath cartridge, respectively, the sheath manipulation base configured for releasable connection to the sheath cartridge and configured to be linearly movable along a longitudinal axis of the sheath manipulation base, at least one of the first and second sheath elements being a second driven element and being linearly driveable in a second predetermined direction for operating the sheath cartridge, the first sheath element of the sheath cartridge being operably engaged with a second tensionable deflection member for laterally deflecting a distal end of a sheath component of the sheath cartridge having the second tensionable deflection member engaged thereto when the second driven element is linearly driven in the second predetermined direction.
