Article Synopsis
- The study explores the use of the CorPath GRX Robotic System for treating intracranial aneurysms, focusing on its advantages such as increased accuracy, minimized procedural time, and the ability to perform procedures remotely.
- Between November 2019 and February 2020, six patients underwent successful robot-assisted embolization, achieving a 100% technical success rate without any complications or need for manual intervention.
- Post-procedure imaging after one year showed that four out of six aneurysms were completely obliterated, suggesting that the robotic system is both safe and effective for this type of medical intervention.
Background: Robotic-assisted endovascular surgery enables us to perform interventions from long distances. This study evaluates the workflow and telecommunication requirements of telerobotic peripheral vascular interventions.
Methods: Ten superficial femoral artery cases were performed by the operator being 44 miles away from the interventional suite, with an endovascular robotic system, on a high-fidelity endovascular simulator.
Article Synopsis
- The study investigates the impact of network latency on remote robotic-assisted endovascular interventions, specifically measuring how delays in command response affect navigation success and procedural experience.
- Three different vascular targets (femoral, carotid, and coronary) were tested using a robotic system with latency changes from 0 to 1000 ms in a porcine model, with all 65 cases successfully completed.
- Results showed that latency beyond 400 ms was noticeable and slightly affected operators' experience, indicating that for effective remote procedures, latency should ideally remain under 400 ms.
Background: With the recent advent of advanced technologies in the field, treatment of neurovascular diseases using endovascular techniques is rapidly evolving. Here we describe our experience with pre-surgical simulation using the Biomodex EVIAS patient-specific 3D-printed models to plan aneurysm treatment using endovascular robotics and novel flow diverter devices.
Methods: Pre-procedural rehearsals with 3D-printed patient-specific models of eight cases harboring brain aneurysms were performed before the first in-human experiences.
Robotic telestenting performance in transcontinental and regional pre-clinical models.
Catheter Cardiovasc Interv
February 2021
Objectives: This study was conducted to evaluate the association of geographic distance with robotic telestenting performance by comparing performance measures in transcontinental and regional pre-clinical models of telestenting.
Background: Robotic telestenting, in which percutaneous coronary intervention (PCI) is performed on a remotely located patient, might improve PCI access, but has not been attempted over vast distances likely required to reach many underserved regions.
Methods: Telestenting performance was compared in regional (Boston to New York [206 miles]) and transcontinental (Boston to San Francisco [3,085 miles]) ex vivo models of telestenting, wherein a physician in Boston attempted robotic PCI on endovascular simulators in New York and San Francisco, respectively.
Robotic-assisted technology has been used as a tool to enhance open and minimally invasive surgeries as well as percutaneous coronary and peripheral vascular interventions. It offers many potential benefits, including increased procedural and technical accuracy as well as reduced radiation dose during fluoroscopic procedures. It also offers the potential for truly "remote" procedures.
