Abstract
A medicine delivery mechanism or fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a dispensing chamber with an elongated cylindrical cross section (although other shapes can be used) which is formed in the staple housing of the attachment in lieu of a staple port or staple ports, and which has a mouth forming a channel lined at its innermost edge perimeter with inward facing prongs or teeth. The dispensing chamber contains a sac filled with fibrin. A delivery or plunger driver travels within the dispensing chamber to press a sac of fibrin against the inward facing prongs, tearing the sac and releasing the fibrin to push the fibrin through the channel to the treatment site.
