SURGICAL FASTENER ALIGNING INSTRUMENT PARTICULARLY FOR TRANSORAL TREATMENT OF GASTROESOPHAGEAL REFLUX DISEASE

摘要

A surgical instrument (200) includes an end effector (202) having a Clevis (224) and first and second jaws (226, 228) mutually rotatable between open and closed positions. The jaws are proximally directed and laterally displaced relative to an axis of a control shaft (206) of the instrument. The jaws hold first and second parts of a fastener, respectively. The first part includes a base having upstanding tissue piercing posts (256), and the second part includes another base defining apertures for receiving the posts, as well as a portion movable relative to the second base. When the upstanding posts are inserted into the apertures, the movable portion can be moved into a second configuration to lock the parts of the fastener together. The instrument is adapted to move the second part into the second configuration. A method for using the apparatus and fastener are also provided.
