Abstract
A deployment device for bringing a sealing plug into position within a puncture tract or incision, and bringing an anchor into position adjacent a tissue puncture, is provided. The deployment device is designed to facilitate easier positioning of the sealing plug, wherein a separate tamping tool is not required. The sealing plug is held in place on the shaft of the anchor by a structure, for example, a knob or boss. The anchor, anchor shaft, and sealing plug may be made of various biocompatible resorbable materials such that the anchor may resorb very quickly, leaving the tissue or artery lumen clear, and the sealing plug may resorb more slowly, to assist in maintaining hemostasis. The deployment device may include a bypass device which maintains the anchor in either an extended or bent configuration. Further, the anchor may include at least one rib, to provide support to the anchor.
