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.

First claim

What is claimed is:

1. An apparatus comprising:
an eversion mechanism 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 configured to partially evert a distal portion of 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 being further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage; and
a suturing mechanism configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

2. The apparatus of claim 1 , wherein the first proximal portion of the end of the donor passage is configured to meet the proximal portion of the receiving passage at an acute angle.

3. The apparatus of claim 1 , wherein the eversion mechanism includes a first suction device configured to apply suction to an external surface of at least the distal portion of the opening of the receiving passage.

4. The apparatus of claim 1 , wherein the suturing mechanism further comprises a plurality of guide sections, wherein an interior surface of each guide section defines a partial helical channel.

5. The apparatus of claim 4 , further comprising a helical needle configured to receive an end of a suture and further configured to conform to the partial helical channel defined by the interior surface of each guide section as the helical needle is motivated through the plurality of guide sections to suture the passage juncture.

6. The apparatus of claim 1 , further comprising a stabilizer configured to support the suturing mechanism against a body passage adjacent the opening of the receiving passage.

7. A system comprising:
a support body configured to be inserted into a body;
a camera system operably coupled with the support body, wherein the camera system is configured to convey imaging data from the support body to an operator;
an eversion mechanism 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 configured to partially evert a distal portion of 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 being further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage; and
a suturing mechanism configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

8. The system of claim 7 , wherein the first proximal portion of the end of the donor passage is configured to meet the proximal portion of the receiving passage at an acute angle.

9. The system of claim 7 , wherein the eversion mechanism includes a first suction device configured to apply suction to an external surface of at least the distal portion of the opening of the receiving passage.

10. The system of claim 7 , wherein the suturing mechanism further comprises a plurality of guide sections, wherein an interior surface of each guide section defines a partial helical channel.

11. The system of claim 7 , further comprising a helical needle configured to receive an end of a suture and further configured to conform to the partial helical channel defined by the interior surface of each guide section as the helical needle is motivated through the plurality of guide sections to suture the passage juncture.

12. The system of claim 7 , further comprising a stabilizer configured to support the suturing mechanism against a body passage adjacent the opening of the receiving passage.
