Abstract
An endoscopic tissue apposition device that includes a vacuum chamber configured to securely hold a portion of tissue therein, the vacuum chamber being defined by a proximal wall and a distal wall opposite to the proximal wall. Working and vacuum channels are provided in communication with the vacuum chamber. A portion of tissue is held in the vacuum chamber when vacuum is applied in the vacuum chamber through the vacuum channel. A carrier needle is disposed on a proximal side of the vacuum chamber and is longitudinally advanceable into and across the vacuum chamber, while a punch needle is disposed on a distal side of the vacuum chamber and is configured to receive the carrier needle therein. A hold and release mechanism holds and releases the punch needle to facilitate joining portions of tissue together.
