**4.5 Robotic-assisted remote interventions**

The upgrade on the CorPath system allowed the GRX model to be controlled remotely. Hence tele-stenting become a possible treatment option and a new aspect of robotic-assisted therapies become available. This approach does not require the operator to be in the operating room or next to the patient, the whole system is capable of being controlled from another hospital or office through telecommunication. The setup is provided by local area network and the two sites are using telepresence systems. This includes patient's vital parameters, live or stored fluoroscopy data displayed on monitors and an additional monitor with an overall view of the suite. Communication between the medical staff can be enhanced through wireless headsets [32]. There are multiple studies discussing the safety and feasibility of remote PCI [33–35]. Key factors of the procedure are the network stability and the communication of the medical team. Studies on simulators and on in-vivo models focusing on network latency reported that signal transmission should be below 250 ms not to influence the procedure outcome. The tele-stenting involved five in-human PCIs with a 53 ms mean command delay from a 20 miles distance [36].
