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.
An anchor assembly for sealing a tissue puncture, the anchor assembly comprising a flexible anchor, an anchor shaft configured to receive a sealing plug made of a bioresorbable material so that the anchor shaft passes through the sealing plug, and a boss, the anchor shaft possessing a distal-most end and a proximal-most end, the flexible anchor being fixedly disposed at the distal-most end of the anchor shaft so that the flexible anchor is positionally fixed with respect to the distal-most end of the anchor shaft, the boss being fixedly disposed at the proximal-most end of the anchor shaft so that the boss is positionally fixed with respect to the proximal-most end of the anchor shaft, the anchor comprising a bioresorbable material that resorbs more rapidly than a bioresorbable material composing the anchor shaft and a bioresorbable material composing the boss, the flexible anchor being a flexible low profile body that is bendable or foldable to be positioned inside a deployment device for delivery to a location of the tissue puncture.
An anchor assembly for sealing a tissue puncture, the anchor assembly comprising:
