Abstract
The present invention relates to an improved endoscopic tissue apposition device having multiple suction ports. The invention permits multiple folds of tissue to be captured in the suction ports with a single positioning of the device and attached together by a tissue securement mechanism such as a suture, staple or other form of tissue bonding. The improvement reduces the number of intubations required during an endoscopic procedure to suture tissue or join areas of tissue together. The suction ports may be arranged in a variety of configurations on the apposition device to best suit the desired resulting tissue orientation. The inventive tissue apposition device may also incorporate tissue abrasion means to activate the healing process on surfaces of tissue areas that are to be joined by operation of the device to promote a more secure attachment by permanent tissue bonding.
