The surgical suture includes a plurality of flexible protrusions extending from the shaft, and a lumen extending between the leading and trailing ends of the shaft. The shaft includes a plurality of openings formed in the outer surface thereof that are in communication with the lumen. The shaft includes a first axial opening at the leading end thereof in communication with the lumen and a second axial opening at the trailing end thereof in communication with the lumen. A flowable material may be disposed in the lumen. After the surgical suture is implanted, the flowable material is adapted to pass from the lumen and through the plurality of openings in the outer surface of the shaft for contacting tissue surrounding the suture.
