Compressible adjunct with crossing spacer fibers

An adjunct, comprising:

• a first layer to interface with a staple cartridge;
• a second layer to interface with tissue;
• and
• a support layer intermediate the first layer and the second layer, wherein the support layer defines cavities, and wherein the adjunct is configurable between:
• an uncompressed state in which the cavities are a first height;
• and
• a compressed state in which the cavities are a second height less than the first height;
• wherein the adjunct comprises a polymeric composition that comprises a pharmaceutical agent, wherein the pharmaceutical agent is to be released from the polymeric composition to effect tissue healing at a faster rate than without the pharmaceutical agent.

A compressible adjunct, comprising:

• a first layer to interface with a staple cartridge;
• a second layer to interface with tissue;
• and
• a hollow support layer intermediate the first layer and the second layer, wherein the hollow support layer defines interconnected cavities;
• wherein the compressible adjunct comprises a polymeric composition that comprises a pharmaceutical agent, wherein the pharmaceutical agent is to be released from the polymeric composition to effect tissue healing at a faster rate than without the pharmaceutical agent.
