The elongated body (102) includes at least one channel (120) extending through the inner surface (112) and the outer surface (104), the channel (120) defined between an inner surface of one of the plurality of barbs (110) and a cut outer surface of the elongated body (102). A wound treatment material ("W") is disposed within the lumen (108) of the elongated body (102). The barb (110) is configured to move between a first position to close the channel (120) and retain the wound treatment material ("W") within the lumen (108) and a second position to open the channel (120) and permit the release of the wound treatment material ("W") therethrough.1/2 112 2A- 1 10 "a" b" 100 106a 110 120 110110 x~/ -w-x 108 106 102 2A--a-i102 FIG.
