Coronary Connector Facilitated Total Endoscopic Coronary Artery Bypass: An Ex Vivo Feasibility Study.
Objective: Totally endoscopic coronary artery bypass (TECAB) procedures pose significant challenges, motivating the development of Octocon, an automated endoscopic connector designed for coronary anastomoses in off-pump and endoscopic settings. This feasibility study aimed to assess Octocon's functionality and maneuverability in closed-chest conditions during robot-assisted TECAB simulations.
Methods: The Octocon deployment comprises a 3-step procedure. Initially, delicate self-aligning microstapling technology is used to attach connector halves to individual blood vessels. Subsequently, the connector halves are joined to accomplish the anastomosis process. TECAB conditions were simulated using a dedicated box housing ex vivo porcine hearts. The study, conducted by 3 experienced surgeons, investigated the feasibility and standardization potential of a robot-assisted procedure employing Octocon. It evaluated maneuverability in closed-chest conditions and assessed the effectiveness of grafting internal mammary artery segments to different heart regions using single graft, jump graft, and Y-graft constructions.
Results: The robot-assisted procedure, using 4 standard instruments, successfully completed all 3 steps in 18 anastomotic procedures. In 96% of cases, the procedural steps were accomplished on the first attempt. The feasibility of constructing jump graft and Y-graft geometries on both anterior and posterior heart walls was demonstrated. Furthermore, experiences affirmed the device's endoscopic user-friendliness, ease of teachability, reproducibility, and potential to achieve expedient, leak-free anastomoses.
Conclusions: This ex vivo study confirmed Octocon's potential suitability and functionality for TECAB. The device can create diverse grafting strategies and achieve wide-open vascular connections on various heart regions, highlighting its potential in advancing minimally invasive, robot-assisted coronary procedures. These promising results justify further exploration for integration into clinical practice.
