Adjunct material for delivery to stomach tissue
View Patent ↗Adjunct materials for delivery to stomach tissue are provided. In general, the adjunct materials can be configured to be delivered to tissue by deployment of staples from a cartridge body of a surgical stapler. The adjunct material can have a structure effective to cause a desired reaction in the stomach tissue. The adjunct material can include an effective amount of one or more medicants disposed within and releasable from the adjunct material for delivery to the stomach tissue to encourage the desired reaction. The adjunct material can be in the form of at least one of a film and a foam that is releasably retained on the cartridge body. Methods of using a staple cartridge assembly or an end effector to apply such adjunct materials to stomach tissue are also provided.
1. A staple cartridge assembly for use with a surgical stapler, comprising:
a cartridge body having a plurality of staple cavities, each staple cavity having a surgical staple disposed therein;
a biocompatible adjunct material in the form of at least one of a film and a foam that is releasably retained on the cartridge body and configured to be delivered to an external surface of stomach tissue of a patient by deployment of the staples in the cartridge body, wherein after the deployment of the staples the adjunct material and the staples are configured to move from the external surface of the stomach tissue, through the stomach tissue, and into the patient's stomach cavity; and
at least one medicant disposed within the adjunct material, the at least one medicant being effective to encourage the movement of the adjunct material.
2. The assembly of claim 1 , wherein the at least one medicant is effective to encourage healing of the stapled stomach tissue.
3. The assembly of claim 1 , wherein the adjunct material is a film having an abrasive surface.
4. The assembly of claim 1 , wherein the adjunct material is non-bioabsorbable.
5. The assembly of claim 1 , wherein the adjunct material is configured to swell.
6. An end effector for a surgical instrument, comprising:
a first jaw having a cartridge body removably attached thereto, the cartridge body having on a tissue-facing surface thereof a plurality of staple cavities configured to seat staples therein;
a second jaw having an anvil with a plurality of staple forming cavities formed on a tissue-facing surface thereof, wherein at least one of the first and second jaws is movable relative to the other;
a biocompatible adjunct material in the form of at least one of a film and a foam that is releasably retained on at least one of the tissue-facing surfaces of the first and second jaws and configured to be delivered to an external surface of stomach tissue of a patient by deployment of the staples in the cartridge body, wherein after the deployment of the staples the adjunct material and the staples are configured to move from the external surface of the stomach tissue, though the stomach tissue, and into the patient's stomach cavity; and
at least one medicant disposed within the adjunct material, the at least one medicant being effective to encourage the movement of the adjunct material.
7. The end effector of claim 6 , wherein the at least one medicant is effective to encourage healing of the stapled stomach tissue.
8. The end effector of claim 6 , wherein the adjunct material is a film having an abrasive surface.
9. The end effector of claim 6 , wherein the adjunct material is non-bioabsorbable.
10. The end effector of claim 6 , wherein the adjunct material is configured to swell.
