“…1). 38 Perhaps the most exciting potential benefit of robotic angiography and intervention is the potential for remote operation by a stroke interventionist across a network of hospitals equipped with the necessary angiography infrastructure. This may dramatically broaden the geographic reach of each stroke interventionist, allowing patients with large vessel occlusions to reach a suitable treatment location even when the interventionist is farther away.…”

During the past 20 years, the traditional supportive treatment for stroke has been radically transformed by advances in catheter technologies and a cohort of prominent randomized controlled trials that unequivocally demonstrated significant improvement in stroke outcomes with timely endovascular intervention. However, substantial limitations to treatment remain, among the most important being timely access to care. Nonetheless, stroke care has continued its evolution by incorporating technological advances from various fields that can further reduce patients' morbidity and mortality. In this paper the authors discuss the importance of emerging technologies—mobile stroke treatment units, telemedicine, and robotically assisted angiography—as future tools for expanding access to the diagnosis and treatment of acute ischemic stroke.

“…In recent years, there has been a growing interest in robotassisted catheter navigation systems. Compared to manual catheterization, these platforms could provide advantages such as added stability and precision of motion, increased comfort for the operator, and reduced radiation from the ionizing sources [1]. However, most existing platforms have been designed without consideration of natural bedside manipulation skills and many master controllers fail to utilize the operator's experience obtained from conventional catheterization.…”

“…Recent advances in both imaging and robotic technologies could provide the possibility for an enhanced robot-assisted catheterization. Learning the essential interactive behavior patterns between the catheter and blood vessels as well as between the operator and the catheter from demonstrations, incorporating anatomical information from pre-operative images, and applying them to a semiautonomous and collaborative robotic catheterization within different anatomical geometries, can reduce the cognitive 1 Wenqiang Chi, Jindong Liu, Hedyeh Rafii-Tari and Guang-Zhong Yang are with the Hamlyn Centre for Robotic Surgery, Imperial College London, SW7 2AZ, London, UK (email:wenqiang.chi10@imperial.ac.uk) 2 workload of the operator while improving the quality of the catheter insertion.…”

Abstract-This paper improves a semi-automatic robotic catheterization platform based on previous works [9] by proposing a method to address subject variability. It incorporates anatomical information in the process of catheter trajectories optimization, hence can adapt to the scale and orientation differences among subjects. Statistical modeling is implemented to encode the catheter motions of both proximal and distal sites from demonstrations of one vascular model. Non-rigid registration is applied to find a warping function to map catheter tip trajectories onto other anatomically-similar but shape/scale/orientation different models. Such function can finally generate a robot trajectory to conduct a collaborative catheratization task. Experiments investigate the proposed method in different vascular phantoms. The success rate for semi-automatic cannulation is high, which suggest the method can be potentially applied to different endovascular tasks and vasculature. The proposed robotic approach also show significant improvements in the quality of catheterization over manual approach by achieving smoother and safer catheter paths and reducing contact forces. This work provides insights into catheter task planning and an improved design of handson, ergonomic catheter navigation robots.

“…The manipulation of catheters through complex anatomy has undergone improved consistency and safety through the introduction of robotic catheter navigation systems such as the Hansen Magellan (Hansen Medical, Mountain View, CA, USA) for arterial intervention [1] and the Stereotaxis Niobe (Stereotaxis, St. Louis, MO, USA) for electrophysiology (EP) procedures [2]. The use of these systems has led to greater stability of the catheter, as well as better control, allowing for catheter manoeuvrability though more tortuous vessels.…”

Motion-adapted catheter navigation with real-time instantiation and improved visualisation

The improvements to catheter manipulation by the use of robot-assisted catheter navigation for endovascular procedures include increased precision, stability of motion and operator comfort. However, navigation through the vasculature under fluoroscopic guidance is still challenging, mostly due to physiological motion and when tortuous vessels are involved. In this paper, we propose a motion-adaptive catheter navigation scheme based on shape modelling to compensate for these dynamic effects, permitting predictive and dynamic navigations. This allows for timed manipulations synchronised with the vascular motion. The technical contribution of the paper includes the following two aspects. Firstly, a dynamic shape modelling and real-time instantiation scheme based on sparse data obtained intra-operatively is proposed for improved visualisation of the 3D vasculature during endovascular intervention. Secondly, a reconstructed frontal view from the catheter tip using the derived dynamic model is used as an interventional aid to user guidance. To demonstrate the practical value of the proposed framework, a simulated aortic branch cannulation procedure is used with detailed user validation to demonstrate the improvement in navigation quality and efficiency.
