“…Its clinical practicality was demonstrated in this study, as well as in an earlier report by Sakaguchi and colleagues. 7 It is useful for not only MICS-CABG, but also other cardiac operations performed through a small thoracotomy such as surgical pacemaker lead implantation, pericardial LV ablation, and left atrial appendage closure. The device was approved by the U.S. Food and Drug Administration in 2020.…”

Purpose. We developed a heart positioner, the Tentacles NEO, specifically designed for minimally invasive coronary artery bypass grafting (MICS-CABG).Description. The device has 3 flexible suction tubes, with a suction cup at the tip of each tube. The suction tubes can be detached from the device body, allowing them to be manipulated in any direction through a small incision around the small thoracotomy. When the device displaces the heart, the suction cup moves behind the chest wall and does not crowd the operative field.Evaluation. Although the sideways suction force of the new device was as strong as that of the original device, Tentacles, the longitudinal and perpendicular force exerted was approximately 80% of the original device. Nevertheless, the new device could safely and favorably displace the heart in a pig model and even during off-pump CABG via sternotomy. During MICS-CABG, the device was able to displace the heart without crowding the operative field.Conclusions. The new heart positioner, Tentacles NEO, is a useful and practical heart positioner suitable for MICS-CABG.
