Abstract: Coronary Artery Bypass Grafting is a procedure to counter coronary artery disease. This involves a vein graft that is taken from a different part of the body and it is used to bypass the blockage that exists within the coronary artery. Manual suturing has been the procedure to conduct this surgery and this often depends on the skill of the surgeon. Furthermore, the complexity of this procedure leads to the whole operation being tedious. Hence, devices have been invented to facilitate the anastomosis between the vein graft as well as the coronary artery. Many issues then surfaced with some being the biocompatibility of the device as well as reproducibility of them. This means that the patency rate (likelihood of a blood vessel remaining opened or unblocked) of the bypass grafting may not hold. That is also why manual suturing is considered to be the best, safest and most efficient procedure. Through thorough research, a few concept designs were created using the knowledge gained from evaluating the existing anastomotic devices that are readily available in the market. These devices have varying patency rates and some are yet to be approved for use. Nonetheless, the design concepts generated took into consideration some of the advantageous features of these devices to ensure the functionality of the concepts. A morphological chart was used to create the design concepts and through an evaluation matrix, the best one was selected. Material selection for the device was also done to eliminate any ambiguity and to ensure that biocompatibility is accounted for. Various production options were also identified. Recommendations for future work was also highlighted in this project so that research can be conducted to ensure progress in the future.
