Abstract
Abstract A one piece needle and suture holder is described in which a rounded channel is formed for retention of the suture. One end of the suture exits the channel toward the interior of the channel and is attached to a needle located in a needle holder in the interior of the channel. The channel is formed with an open side, to which are attached a plurality of hinged doors. After the suture is wound in the open channel, the doors are folded over the open side of the channel and are locked in place to retain the suture within the channel. In an alternative embodiment a paper cover is utilized to complete the enclosing channel. To afford ease of winding the suture the bottom of the channel is perforated for the application of a vacuum to the channel during suture winding. Also disclosed is a needle park for retaining the needle in the center of the package. In a preferred embodiment the needle park is backed by a relief flap to enable the needle to be conveniently grasped by a forceps during removal of the needle and suture.
