An anvil for a surgical fastener assembly is disclosed. The anvil has a staple-forming surface upon which a plurality of pockets are displayed for staple formation. First and second sidewalls extend from the staple-forming surface. Cutting guides extend laterally from the sidewalls to provide a uniform surface upon which a user can apply pressure with a scalpel to staple tissue in a direction generally parallel to the vertical staple row. An even margin can be maintained between the staple row and the cut line, thus increasing the degree of confidence and skill that the user can employ when cutting the fastened tissue.

A tissue manipulator is provided which is insertable through an endoscopic tube to enable a surgeon to manipulate tissue inside a body cavity. The endoscopic tissue manipulator includes an expandable tissue manipulating frame adapted to expand transversely through a longitudinal slot in a support tube to provide a spatula-shaped platform which can be manipulated by rotation of the support tube about its longitudinal axis to engage and displace large body organs away from a desired surgical site in a body cavity. The frame consists of a plurality of flexible frame members or wires adapted to flex laterally outward through the longitudinal slot in the support tube into a bow-shaped configuration overlapping the other frame members or wires of the spatula-shaped platform. The instrument can be provided with a single tissue manipulating frame or a pair of frames which are expandable through separate longitudinal slots in the support tube to provide a pair of spatula-shaped platforms to engage the tissue. The pair of frames of the dual frame embodiment may be actuated together or independently.

A pyloroplasty/pylorectomy shield having a base member and a proximally extending shield member. The pyloroplasty/pylorectomy shield has attachment means for engagement with a circular stapler. The pyloroplasty/pylorectomy shield also has dilation means for progressively dilating a sphincter. The pyloroplasty/pylorectomy shield is used with a circular stapler to perform a pyloroplasty/pylorectomy. Also disclosed is a method of performing a pyloroplasty/pylorectomy using the pyloroplasty/pylorectomy shield of the present invention. The pyloroplasty/pylorectomy shield has numerous advantages including reduced trauma, decreased misalignment resulting in improved stapling and improved positioning of the pyloroplasty/pylorectomy.

An applicator is provided for applying a sheet of surgical material, e. g. , an adhesion barrier or other surgical fabric, to internal body tissue. The applicator includes an expandable operating tip which is insertable into an endoscopic tube through an incision in a body to enable a surgeon to apply the adhesion barrier or other surgical fabric to tissue inside the body. A preferred embodiment of the applicator includes a set of telescoping tubes comprising an outer delivery tube, a intermediate deployment tube, and a inner irrigation tube. An expandable spreader tip is mounted at the distal end of the irrigation tube and connected to the distal end of the deployment tube. By advancing the deployment tube and irrigation tube relative to the delivery tube, the spreader tip is exposed at the distal end of the delivery tube. The spreader tip is expanded by movement of the deployment tube relative to the irrigation tube to spread the adhesion barrier over the tissue. A nozzle is provided at the distal end of the irrigation tube for applying a fluid, e. g.
