Abstract
Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.
