Abstract
A wound closure system includes a suture member and a suture grasper. The suture member includes a suture and a retention member engaged to an end of the suture. The retention member is at least partially flexible and defines a central opening. The suture grasper includes a needle defining a distal portion configured for insertion through the central opening of the retention member to retrieve the retention member from an internal surgical site. The distal portion of the needle defines a distally-facing feature configured to at least partially flex the retention member upon insertion of the distal portion into the central opening to permit passage of the distal portion therethrough and a proximally-facing feature configured to inhibit proximal withdrawal of the distal portion through the central opening of the retention member.
