Brief Summary

Patients with coronary artery disease requiring PCI treatment were enrolled in the study. All patients underwent PCI with the robotic R-OneTM System (R-One Vascular Robotics, Cathbot). The system was designed for coronary PCI and consists of 2 major components: the command unit and a bedside robot. The command unit is a radiation-shielded, mobile workstation that was positioned in the corner of the catheterization laboratory. The interventional cardiologist sits at the command unit and remotely performs the PCI using the console joysticks. Commands from the control console are delivered as electrical signals along a communication cable that runs from the control console to the robotic drive, on which a sterile cassette is placed. The cassette, which is loaded with the robot and connected to the guiding catheters, imposes axial and rotational forces on the intracoronary devices. Fluoro-scopic, electrocardiographic, and hemodynamic images are "slaved" to the duplicate monitors inside the cockpit, enabling visualization from a closer distance. After completion of diagnostic angiography, the guiding catheter was positioned at the ostium of the coronary artery and connected to the disposable cassette on the robotic drive. The guidewire was loaded into the cassette before starting the robotic-enhanced PCI. The treatment plan is decided by the doctor according to the patients' situation. All intracoronary devices were to be manipulated exclusively by the robotic system, with bailout to manual conversion when needed. The primary endpoints were clinical procedural success and device technical success. The necessary sample size for testing the endpoint of clinical and technical procedural success was calculated on the basis of the target value. The statistical analysis results show that the lower limit of the 95% confidence interval of the clinical success rate and the technical success rate of the operation is greater than 90% of the target value, and the invalid hypothesis is rejected. Both primary endpoints had to be met for the study to be declared successful. Data were analyzed on an intention-to-treat basis. Standard summary statistics were calculated for all patient and study outcome variables. Continuous variables were summarized using estimated means, standard deviations, minimums, maximums, medians, and interquartile ranges. Categorical data were summarized using frequencies, percentages, and 95% confidence interval.

Outcome Measures

Primary Outcomes (2)

  • Clinical success rate of the surgery

    Calculation formula: Clinical success rate = number of subjects that were clinical successes ÷ number of subjects that received surgical treatment × 100%. Evaluation method: The target lesion was treated with test device, and the residual stenosis in the target vessel (visual description by angiography) reduced to less than 30% after PCI and a TIMI grade of 3. No major adverse cardiovascular events (MACE) occurred in the hospital.

    Operation day

  • Success rate of surgical techniques

    Calculation formula: Technical success rate = number of subjects that were technical successes ÷ number of subjects received surgical treatment × 100% Evaluation method: The Robot-assisted PCI procedure was successfully completed without any unplanned manual assistance or shift to manual operation. Definition of planned manual assistance: During robotic surgery: Reposition of guidewires or stents/balloons, manual translation/rotation of guidewires or stents/balloons to guiding catheters, reposition of guiding catheters and usage of any device that is not compatible with the robotic platform Definition of unplanned manual assistance: Manual translation/rotation of the guidewire and/or manual translation of the stent/balloon once the guidewire has left the guiding catheter Definition of the shift to manual operation: Any situation during the PCI procedure that results in the shift to manual operation. System restart failure during robotic surgery

Study Arms (2)

R-One assisted tele-PCI

EXPERIMENTAL

The investigational device was R-One Vascular Interventional Navigation Control System developed and produced by Robocath, and was composed of a platform (instruction unit, robot, support joint arm), a consumable set (cartridge, instruction unit protective sleeve), and a remote workstation. To achieve remote surgery, remote communication workstations need to be configured at all locations where remote surgery is performed. The remote communication workstation of local operating room will establish the virtual surgery, and the remote communication workstation of the remote control side needs to join the virtual surgery through the invitation code to establish remote control between the two places. After the virtual surgery is established, the two communication workstations need to incorporate the robots nearby into the operation. In this way, the two control consoles can achieve remote control and data exchange.

Device: R-One assisted tele-PCI

R-One assisted on-site PCI

ACTIVE COMPARATOR

The product is designed with a master-slave control, which inserts and retracts guidewires, balloons and stent catheters via a remote-controlled robotic arm. The surgeon inputs the movements through the handle at the master end, and the robot replicates the surgeon's hand movements from the slave end to complete the surgical operation.

Device: R-One assisted on-site PCI

Interventions

Surgeons perform operations using R-One vascular interventional navigation control system from remote control center via 5G. robotic slave executes at procedure site.

R-One assisted tele-PCI

Surgeons perform operations by controlling robot from local console .
