Surgical method and apparatus for resectioning tissue, preferably lumenal tissue, with a remaining portion of an organ being anastomized with staples or other fastening devices, preferably endolumenally. The apparatus may be inserted via a naturally occurring body orifice or a surgical incision and then advanced using either endoscopic or radiological imaging guidance to an area where surgery is to be performed. Under endoscopic or diagnostic imaging guidance the apparatus is positioned so tissue to be resected is manipulated into an inner cavity of the apparatus. The apparatus then cuts the diseased tissue after stapling and retains the diseased tissue within the apparatus. The rent resulting in a border of healthy tissue is anastomosed with surgical staples.

Suction-assisted tissue-engaging devices, systems, and methods are disclosed that can be employed through minimal surgical incisions to engage tissue during a medical procedure through application of suction to the tissue through a suction member applied to the tissue.

A surgical instrument, guide, and method capable of being used for closure of peritoneum fascia, occlusion of bleeding vessels such as inferior epigastric, and for all uses related to accurately passing suture material through a guide into tissue. A tip of a surgical instrument in a standard suture- / needle-driving position with a sharp tip that opens and closes with the surgeon grasping suture material with the sharp tip is provided. Insertion of the tip / suture through tissue until the tip is seen through the peritoneum by direct vision begins the wound-closing procedure. The suture is released by opening and withdrawing the tip from the guide. The suture is recovered by using the guide to redirect the tip and puncturing the tissue opposite the first point of insertion. The tip grasps the suture and pulls the suture through the guide. The suture is pulled outside the wound, providing for rapid closure of the surgical incision. The guide is insertable within the wound to be closed and guides the surgical instrument at a predetermined angle from the longitudinal axis of the guide for optimum wound closure. Alternative embodiments of the guide include providing a slot through which non-linear surgical instruments may pass through an open or enclosed passageway.
