    摘要： An apparatus for performing medical procedures on an anatomical body includes an extension with an element near its distal end to be extended into the body, and a driver that moves the extension axially into the body, and that causes flexure of the distal end of the extension. The movement and flexure of the extension is driven by the driver from the proximal end of the extension, and an electronic controller directs the operation of the driver.

    摘要： An exemplary drive apparatus may include a roller assembly and a roller support. The roller assembly may have a first continuous surface, a second continuous surface, an open configuration for receiving an elongate member, and a closed configuration for securing the elongate member in the roller assembly. The roller assembly imparts axial motion to the elongate member along the first continuous surface, which maintains contact with the elongate member during the axial motion. The roller support rotates the roller assembly about the second continuous surface, which maintains contact with the roller support during rotational motion. The roller assembly and roller support to impart axial and rotational motion, respectively, independently of one another.

    摘要： Various exemplary drive apparatuses and associated methods are disclosed for driving an elongated member, e.g., a catheter, sheath, or guidewire. An exemplary drive apparatus may include a first component and a moveable component, each configured to selectively grip the elongated member. In some examples, the first and moveable components may each include a gripping device. The moveable component may be configured to selectively move axially and rotationally with respect to a support surface to effect axial movement and rotation movement, respectively, of the elongated member with respect to the support surface within a range of motion of the moveable component. The moveable component may be configured to move the elongated member across a predetermined movement having a magnitude greater than the range of motion.
