Flexible robotic catheters are an emerging technology which provide an elegant solution to the challenges of conventional endovascular intervention. Originally developed for interventional cardiology and electrophysiology procedures, remotely steerable robotic catheters such as the Magellan system enable greater precision and enhanced stability during target vessel navigation. These technical advantages facilitate improved treatment of disease in the arterial tree, as well as allowing execution of otherwise unfeasible procedures. Occupational radiation exposure is an emerging concern with the use of increasingly complex endovascular interventions. The robotic systems offer an added benefit of radiation reduction, as the operator is seated away from the radiation source during manipulation of the catheter. Pre-clinical studies have demonstrated reduction in force and frequency of vessel wall contact, resulting in reduced tissue trauma, as well as improved procedural times. Both safety and feasibility have been demonstrated in early clinical reports, with the first robot-assisted fenestrated endovascular aortic repair in 2013. Following from this, the Magellan system has been used to successfully undertake a variety of complex aortic procedures, including fenestrated/branched endovascular aortic repair, embolization, and angioplasty.

Objective: To evaluate the safety and effectiveness of robot-assisted percutaneous coronary intervention (R-PCI) compared to traditional manual percutaneous coronary intervention (M-PCI).
Methods: This prospective, multicenter, randomized controlled, non-inferior clinical trial enrolled patients with coronary heart disease who met the inclusion criteria and had indications for elective percutaneous coronary intervention. Participants were randomly assigned to either the R-PCI group or the M-PCI group.

Endovascular surgeries generally rely on push-based catheters and guidewires, which require significant training to master and can still result in high stress being exerted on the anatomy, especially in tortuous paths. Because these procedures are so technically challenging to perform, many patients have limited access to high-quality treatment. Although various robotic systems have been developed to enhance navigation capabilities, they can also apply high stresses due to sliding against the vascular walls, impeding movement and raising the risk of vascular damage.

Bronchoalveolar lavage (BAL) is a minimally invasive procedure for diagnosing lung infections and diseases. However, navigating tortuous lung anatomy to the distal branches of the bronchoalveolar tree for adequate sampling using BAL remains challenging. Continuum robots have been used to improve the navigation of guidewires, catheters, and endoscopes and could be applied to the BAL procedure as well.

Objective: Port sites are a common source of perioperative bleeding in robotic cardiac surgery, which can be exacerbated by patient anatomy and anticoagulation. We present results from the liberal usage of a balloon-tipped coudé catheter for tamponade of robotic port sites during robotic mitral surgery.
Methods: All patients who underwent robotic mitral valve surgery at our institution from August 2016 to July 2022 were studied ( = 320).

Background: The ESCAPE-MeVO (Endovascular Treatment to Improve Outcomes for Medium Vessel Occlusions) and DISTAL (Endovascular Therapy plus Best Medical Treatment vs Best Medical Treatment Alone for Medium Vessel Occlusion Stroke) trials failed to demonstrate the superiority of endovascular thrombectomy over best medical management for medium and small vessel occlusions. Potential limitations of these trials include older patient populations, lower presenting National Institutes of Health Stroke Scale (NIHSS) scores, higher rates of premorbid disability, delayed revascularization times, inclusion of both medium and small vessel occlusions, and widespread use of stent retrievers. Here we present M2 occlusion data from the Imperative Trial, evaluating aspiration thrombectomy with the Zoom System.
