A medicinal delivery device adapted to being applied to a surface of an internal organ and exhibiting a three dimensional shaped body with an outer shell and an inner medicinal composition which is released through an underside of the body in either of a dissolving or time release fashion. In one variant, a small plurality (typically between three and a dozen) of engagement prongs are integrally formed with the three dimensional shell and extend from its underside in order to secure the body to the organ. A related variant combines the delivery device with an implantation tool having forward end located gripping fingers actuated by a trigger to engage outer perimeter locations of the delivery device body. Upon location of the body in engaging contact with the organ, the fingers are reverse actuated to release the body during in situ implantation.
