DEVICE AND METHOD FOR PLACEMENT OF TISSUE ANCHORS

摘要

Medical devices and methods for deploying tissue anchors for simple and reliable closure of openings in tissue are disclosed. The medical device generally includes an access sheath (22) and a flexible puncturing device (24). The flexible puncturing device is sized to be slidably received by the access sheath. The flexible puncturing device has a lumen sized to receive the tissue fastener (10). The flexible puncturing device is operable between a first linear configuration and a second non-linear configuration (Fig. 1). A distal end of the flexible puncturing device is laterally spaced from the access sheath in the second non-linear configuration, and preferably retroflexes to provide placement of the tissue anchors on a proximal side of the tissue.
