<p>A suturing device (10) includes an elongated tubular member (100) defining a longitudinal axis ("A"). The elongated tubular member (100) has a proximal portion (104) and a distal portion (102). A head assembly (200) extends from the distal portion (102) of the elongated tubular member (100) and is disposed about the longitudinal axis ("A"). The head assembly (200) includes one or more rotatable barb holders (220,240) coupled thereto. The rotatable barb holders (220,240) are configured to releasably retain a barb (230,250) thereon. The rotatable barb holders (220,240) are rotatable between a first position, wherein the barb (230,250) is positioned adjacent the elongated tubular member (100), and a second position, wherein the barb (230,250) is radially spaced from the elongated tubular member (100).
