Abstract
A differential drive for manipulating an elongated device includes a drive mechanism configured to provide rotational and linear movement to the elongated percutaneous device. The drive mechanism including a platform rotatably supported by a support and a linear drive operatively coupled to the platform. A first motor operatively rotates the platform relative to the support and moving a portion of the linear drive relative to the platform. A second motor operatively rotates the platform relative to the support and moving a portion of the linear drive relative to the platform.

A differential drive for manipulating an elongated percutaneous device comprising:
- a drive mechanism configured to provide rotational and linear movement to the elongated percutaneous device, the drive mechanism including a unitary platform rotatably supported by a support and a linear drive operatively coupled to the unitary platform;
- a first motor operatively rotating the unitary platform relative to the support and moving a portion of the linear drive relative to the unitary platform;
- a second motor operatively rotating the unitary platform relative to the support and moving a portion of the linear drive relative to the unitary platform, wherein the unitary platform operatively rotated by the first motor is the same unitary platform operatively rotated by second motor;
- wherein the linear drive includes at least one drive member operatively connected to the first motor and the second motor;
- the linear drive includes at least one pair of a drive member and a driven member biased toward the drive member, where the elongated percutaneous device is positioned between the drive member and the driven member;
- and the drive member is a roller wheel operatively connected to a gear in a gear chain operatively coupled to the first motor and to the second motor.
