]. The latest generation robotic platform is the CorPath®GRXSystem(CorindusInc.,Massachusetts,USA),
which is composed of an interventional cockpit and a single use cassette incorporate
within a robotic arm. The cassette has a dedicated “wire track” to control 0.014”
or 0.018” wires and a dedicated “device track” to advance/retrieve balloons and stents
(Fig.1A). One limitation of the current cassette is the absence of a specific “track” designed
for the commonly utilized 0.035” wire[
]. The possibility of controlling this wire is important particularly for peripheral
endovascular procedures, where the 0.035’’wire is commonly used to advance catheters,
balloons and stents.

One limitation of current generation robotic systems is the lack of a specific “track” designed for the commonly utilized 0.035” wire . We used ex vivo simulations to develop a new technique that allows the latest-generation Robotic System to maneuver 0.035”wires, which allows full robotic control for interventional procedures.
