Tubular surgical constructs including adjunct material

1. A method of using a surgical device comprising

a tubular construct having an inner lumen extending therethrough, the tubular construct being configured to be delivered to a tissue lumen and be positioned therein so as to provide structural support to the tissue lumen, the tubular construct being radially collapsible, and the tubular construct including a scaffold that includes a plurality of circumferential rings and a support member that attaches the circumferential rings together and that holds each of the rings in a substantially constant axial position along a longitudinal axis of the tubular construct,

a biocompatible adjunct material disposed on the tubular construct, the adjunct material being configured to be delivered to the tissue lumen with the tubular construct, and

an effective amount of at least one medicant disposed within and releasable from the adjunct material, each of the at least one medicants being effective to provide a desired effect on tissue in a predetermined manner,

the method comprising:

positioning a circular surgical stapler at a target location within a patient within a lumen of a tissue of the patient, the stapler having releasably coupled to a distal end thereof the tubular construct having the adjunct material disposed thereon;

with the stapler positioned at the target location, actuating the stapler to deploy staples from the stapler and into the tissue, the deployed staples securing the tubular construct within the lumen of the tissue; and

removing the stapler from the patient, the tubular construct remaining within the lumen.

2. The method of claim 1 , wherein the adjunct material is in the form of at least one of a fiber lattice and a film.

3. The method of claim 1 , wherein the scaffold has a plurality of pores configured to facilitate tissue ingrowth.

4. The method of claim 1 , wherein the tubular construct includes a funnel shape with a smaller diameter at a first end of the shape than at a second, opposite end of the shape.

5. The method of claim 1 , wherein the tubular construct includes first and second independent tubular members;

prior to the actuation of the stapler, the first tubular member is releasably retained on an anvil of the stapler and the second tubular member is releasably retained on an cartridge assembly of the stapler; and

the actuation releases the first tubular member from the anvil and releases the second tubular member from the cartridge assembly.

6. The method of claim 1 , wherein the adjunct material is in the form of a fiber lattice having at least two distinct heterogeneous fiber lattice sections, the at least two distinct heterogeneous fiber lattice sections including a first fiber lattice section having fibers extending along a longitudinal axis of the tubular construct and a second fiber lattice section having fibers extending annularly around the longitudinal axis of the tubular construct, the longitudinal axis of the tubular construct being substantially parallel to a longitudinal axis of the lumen having the tubular construct secured therein.

7. The method of claim 1 , wherein the tissue includes one of an intestine and an esophagus.

8. The method of claim 1 , wherein the adjunct material covers an exterior surface of the scaffold and does not cover at least a portion of an interior surface of the scaffold such that the support member is not exposed on the exterior surface and is exposed on the at least the portion of an interior surface to facilitate tissue growth when the tubular construct is within the lumen.

9. The method of claim 1 , wherein deploying the staples causes the staples to pierce through the tubular construct and the adjunct material.

10. A method of using an end effector comprising

a cartridge assembly having a cartridge body removably attached thereto, the cartridge body having on a tissue-facing surface thereof a plurality of annularly-arranged staple cavities configured to seat staples therein,

an anvil having a plurality of annularly-arranged staple forming cavities formed on a tissue-facing surface thereof, at least one of the cartridge assembly and the anvil being movable relative to the other,

a tubular construct releasably retained on each of the cartridge assembly and the anvil, the tubular construct having an inner lumen extending therethrough, the tubular construct being configured to be delivered to a tissue lumen by deployment of the staples in the cartridge body, the tubular construct being radially collapsible, and the tubular member including a scaffold that includes a plurality of circumferential rings and a support member that attaches the circumferential rings together and that holds each of the rings in a substantially constant axial position along a longitudinal axis of the tubular construct,

a biocompatible adjunct material disposed on the tubular construct, the adjunct material being configured to be delivered to the tissue lumen with the tubular construct, and

an effective amount of at least one medicant disposed within and releasable from the adjunct material, each of the at least one medicants being effective to provide a desired effect on tissue in a predetermined manner,

the method comprising:

positioning a circular surgical stapler at a target location within a patient within a lumen of a tissue of the patient, the stapler having the end effector at a distal end thereof;

with the stapler positioned at the target location, actuating the stapler to deploy the staples from the cartridge body and into the tissue, the deployed staples securing the tubular construct within the lumen of the tissue; and

removing the stapler from the patient, the tubular construct remaining within the lumen.

11. The method of claim 10 , wherein the adjunct material is in the form of at least one of a fiber lattice and a film.

12. The method of claim 10 , wherein the scaffold has a plurality of pores configured to facilitate tissue ingrowth.

13. The method of claim 10 , wherein the tubular construct includes a funnel shape with a smaller diameter at a first end of the shape than at a second, opposite end of the shape.

14. The method of claim 10 , wherein the tubular construct includes first and second independent tubular members.

15. The method of claim 14 , wherein the first tubular member is releasably retained on the anvil, and the second tubular member is releasably retained on the cartridge assembly.

16. The method of claim 10 , wherein the adjunct material is in the form of a fiber lattice having at least two distinct heterogeneous fiber lattice sections, the at least two distinct heterogeneous fiber lattice sections including a first fiber lattice section having fibers extending along a longitudinal axis of the tubular construct and a second fiber lattice section having fibers extending annularly around the longitudinal axis of the tubular construct, the longitudinal axis of the tubular construct being substantially parallel to a longitudinal axis of the lumen having the tubular construct secured therein.

17. The method of claim 10 , wherein the tissue includes one of an intestine and an esophagus.

18. A method of using a surgical device comprising

a tubular construct having an inner lumen extending therethrough, the tubular construct being configured to be delivered to a tissue lumen and be positioned therein so as to provide structural support to the tissue lumen, the tubular construct being radially collapsible,

a biocompatible adjunct material disposed on the tubular construct, the adjunct material being configured to be delivered to the tissue lumen with the tubular construct, and

an effective amount of at least one medicant disposed within and releasable from the adjunct material, each of the at least one medicants being effective to provide a desired effect on tissue in a predetermined manner,

the method comprising:

positioning a circular surgical stapler at a target location within a patient within a lumen of a tissue of the patient, the stapler having releasably coupled to a distal end thereof the tubular construct having the adjunct material disposed thereon;

with the stapler positioned at the target location, actuating the stapler to deploy staples from the stapler and into the tissue, the deployed staples securing the tubular construct within the lumen of the tissue, wherein deploying the staples causes the staples to pierce through the tubular construct and the adjunct material; and

removing the stapler from the patient, the tubular construct remaining within the lumen.
