Abstract

A modular end effector delivers a therapeutic agent onto tissue that has been severed and/or stapled. The end effector is removably attached to a device. The device applies force to a piston of the end effector. The force causes a distal movement of a piston along a wall disposed within the end effector. The piston engages with agents stored on opposite sides of the wall, moving the agents distally to a mixture space. The agents are mixed in the mixture space and expelled through a tip. Staples may be embedded in or disposed below a foam block, which is disposed within a staple cartridge. Via an endoscopic stapling device, coated staples are driven through tissue while interacting with another agent on the device or the cartridge. The interaction forms a tissue restoring material that is applied onto the tissue.
