Tubular surgical constructs including adjunct material

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.

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.
