Abstract
An apparatus comprises a housing including an instrument interface. The instrument interface is configured to releasably engage a distal portion of an endoscope. The apparatus also comprises a drive system coupled to the housing and configured to releasably engage a drive element extending from the endoscope. The apparatus may also comprise an arc-shaped needle coupled to the drive system and a tissue apposition system. The tissue apposition system may comprise a tissue chamber in the housing across which a trajectory of the arc-shaped needle extends and a tissue biasing component configured to draw tissue into the tissue chamber.
