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.
Claims27
An apparatus 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;
- and
- 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 the second motor.
An apparatus for manipulating an elongated percutaneous device comprising:
- a drive mechanism configured to rotate and translate 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 configured to rotate the unitary platform relative to the support and move a first portion of the linear drive relative to the unitary platform;
- and
- a second motor configured to rotate the unitary platform relative to the support and move a second portion of the linear drive relative to the unitary platform,
- wherein rotation of the first motor and the second motor in a first manner causes translation without rotation of the elongated percutaneous device and rotation of the first motor and the second motor in a second manner causes rotation without translation of the elongated percutaneous device.
