Compressible adjunct with fluid control feature

A compressible adjunct for use with a surgical cartridge is provided. In one exemplary embodiment, a compressible adjunct includes a biocompatible adjunct material configured to be releasably retained on a staple cartridge and configured to be delivered to tissue by deployment of staples in the staple cartridge. The adjunct material includes a lattice primary structure having at least one absorbable sub-structure formed in the lattice primary structure, the at least one absorbable sub-structure configured to control fluid movement through the adjunct material such that when the adjunct material is in a tissue deployed state, the at least one absorbable sub-structure is configured to absorb fluid flow through the adjunct material. The fluid motion affects healing of tissue adjacent to the adjunct material. A stapling assembly for use with a surgical stapler is also provided. 提供了与外科仓一起使用的可压缩附属物。在一个示例性实施方案中，可压缩附属物包括生物相容性附属材料，该生物相容性附属材料被构造成能够可释放地保持在钉仓上，并且被构造成能够通过该钉仓中的钉的部署而被递送到组织。该附属材料包括晶格主结构，该晶格主结构具有形成在该晶格主结构中的至少
