Endovascular intervention is rapidly evolving, allowing more complex pathologies to be managed in a minimally invasive fashion. Although clearly preferable than open surgery for patients with age- or disease-related comorbidities, patient-specific anatomical factors often present a technical challenge even for experienced interventionalists. The use of endovascular robotic technology is a comparatively new field of work considering existing applications in cardiac intervention including atrial fibrillation, mapping, and coronary stent implantation. Several commercially available devices have been designed specifically for use within the vascular tree and utilize a variety of engineering principles to facilitate control of the catheter tip. The Niobe Navigation System (Stereotaxis, USA) was designed for cardiac intervention and consists of two permanent magnets mounted on either side of the fluoroscopy table creating a spherical uniform magnetic field. The computer workstation allows the operator to select the desired field vectors by changing the orientation of the outer magnets relative to each other. The catheter tip has small magnetic implants, which are navigated by the magnetic field.

Rafii-Tari H, Payne CJ, Riga C, et al., 2012, Assessment of navigation cues with proximal force sensing during endovascular catheterization, Pages: 560-567, ISSN: 0302-9743
Despite increased use of robotic catheter navigation systems for endovascular intervention procedures, current master-slave platforms have not yet taken into account dexterous manipulation skill used in traditional catheterization procedures. Information on tool forces applied by operators is often limited. A novel force/torque sensor is developed in this paper to obtain behavioural data across different experience levels and identify underlying factors that affect overall operator performance. The miniature device can be attached to any part of the proximal end of the catheter, together with a position sensor attached to the catheter tip, for relating tool forces to catheter dynamics and overall performance. The results show clear differences in manipulation skills between experience groups, thus providing insights into different patterns and range of forces applied during routine endovascular procedures. They also provide important design specifications for ergonomically optimized catheter manipulation platforms with added haptic feedback while maintaining natural skills of the operators.
