Evaluation of Fully Teleoperated Robotic Endovascular Interventions with Haptic Feedback: The SENTANTE Endovascular Robotic System.
Article in Cardiovascular and interventional radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo evaluate a fully robotic, teleoperated system for performing various endovascular interventions in a preclinical porcine model. MATERIALS AND
methodsThe SENTANTE™ Endovascular Robotic System was assessed in six healthy porcine subjects using standard endovascular devices. Outcomes were assessed via procedural monitoring and gross pathological analysis. Haptic feedback performance was qualitatively assessed by the operators using a four-point scale (1 = very good, 2 = fair, 3 = poor, 4 = inadequate).
resultsA total of 18 endovascular interventional procedures were successfully completed, including renal artery stenting (3), embolization of the superior right renal artery branch (3), percutaneous transluminal angioplasty (PTA) of the superior mesenteric artery (3), left vertebral artery stenting (3), contralateral iliac artery PTA (3), and ipsilateral iliac artery stenting (3). All procedures (100%) were completed without manual conversion, including pre and post-procedural angiography, resulting in near-zero operator radiation exposure. The system was compatible with standard guidewires (0.014″, 0.018″, and 0.035″), catheters (2.7-8 Fr), and pushable coils (0.018″ and 0.035″). Post-procedural angiography demonstrated no signs of vessel injury. Minimal vessel trauma was observed in 3 of 16 target vessels during gross necropsy. Haptic feedback was rated as very good in three test models and as fair in the remaining three.
conclusionsIn a preclinical model, the SENTANTE™ system demonstrated the feasibility of performing endovascular interventions via teleoperation, including angiography, stenting, coil embolization, and PTA. Its compatibility with standard devices, haptic feedback, and elimination of operator radiation exposure support progression to clinical feasibility trials.
