    摘要： A retracting tip trocar assembly including a trocar tube and a shaft having a piercing tip at one end thereof. The device includes a retracting mechanism which allows the piercing tip to be held in a cutting position upon application of an insertion force such as when the piercing tip is pressed against a wall of a human body cavity. Upon release of the insertion force, such as when the piercing tip passes through the wall, the retracting mechanism causes the piercing tip to be retracted into the trocar tube.

    摘要： A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.
