      The latest generation robotic platform is the CorPath GRX System (Corindus Inc, Waltham, MA), which is composed of an interventional cockpit and a single-use cassette incorporated within a robotic arm. The cassette has a dedicated “wire track” to control 0.014-inch or 0.018-inch wires and a dedicated “device track” to advance and retrieve balloons and stents (Fig. 1A). One limitation of the current cassette is the absence of a specific “track” designed for the commonly used 0.035-inch wire.

      The possibility of controlling this wire is important, particularly for peripheral endovascular procedures, in which the 0.035-inch wire is commonly used to advance catheters, balloons, and stents.
