Full eversion anastomosis juncture formation and suturing

A method comprising:

• at a first opening in a side of a receiving passage, everting a first edge of the first opening around a periphery of the first opening to form a receiving flange that presents a first interior face;
• providing a donor passage that has an end that terminates in a second opening;
• everting a second edge of the second opening to form a donor flange that presents a second interior face;
• positioning the second interior face of the donor passage adjacent the first interior face of the receiving passage to form a passage juncture;
• and
• motivating a filament along a helical path around the passage juncture to suture the second interior face of the donor passage to the first interior face of the receiving passage.

An apparatus comprising:

• a first mechanism configured to engage a first external surface of a first tissue and to hold the first external surface in place in order to present a first flange presenting a first interior face opposite the first external surface;
• a second mechanism configured to engage a second external surface of a second tissue and to hold the second external surface in place in order to present a second flange presenting a second interior face opposite the second exterior surface and to position the second interior surface of the second flange against the first interior face of the first flange at a juncture;
• and
• at least one guide section configured to be disposed adjacent to the juncture of the first flange and the second flange and having an interior surface configured to guide a needle and a filament drawn by the needle through at least one of the first flange and the second flange.

A system comprising:

• a first mechanism configured to engage a first external surface of a first tissue and to hold the first external surface in place in order to present a first flange presenting a first interior face opposite the first external surface;
• a second mechanism configured to engage a second external surface of a second tissue and to hold the second external surface in place in order to present a second flange presenting a second interior face opposite the second exterior surface and to position the second interior surface of the second flange against the first interior face of the first flange at a juncture;
• a first guide section operably coupled with the first mechanism and having a first inner face disposable adjacent to the first flange at the juncture and configured to receive a needle and guide the needle through the first flange;
• a second guide section operably coupled with the second mechanism and having a second inner face disposable adjacent to the second flange at the juncture and configured to receive the needle and guide the needle through the second flange;
• and
• a suturing mechanism configured to motivate the needle through the first guide section and the second guide section, wherein a filament drawn by the needle to form a suture joining the first flange and the second flange.
