Abstract

A staple cartridge assembly is disclosed. The staple cartridge assembly comprises staples including a base, staple legs extending from the base, and a platform extending laterally from the base. The staple cartridge assembly further comprises an implantable layer. The platforms of the staples are configured to support the implantable layer when the staples are implanted into the tissue of a patient. Staples are also disclosed which included an implantable adjunct positioned over the platform of the staple. The implantable adjuncts can include one or more compressible pockets. One or more medicaments can be positioned in the compressible pockets.

Claims

1. A staple cartridge assembly, comprising:
