Wound closure device
A suturing device includes a housing having an elongated tubular member extending from a distal end thereof. A head assembly is disposed at a distal end of the elongated tubular member and is configured to retain a portion of a suture therein. At least one arm member is positioned adjacent the elongated tubular member. Each arm members includes a ferrule assembly disposed at a distal end thereof. Each ferrule assembly is positioned within a recess defined within the elongated tubular member and is configured to releasably retain a ferrule therein. Each ferrule is configured to retain a portion of the suture therein. Each arm member is rotatable to rotate the ferrule assembly disposed thereon between a first position, wherein the ferrule assembly is disposed within the recess, and a second position, wherein the ferrule assembly extends at least partially radially outwardly from the recess.
