An exemplary surgical apparatus may include a feeder belt; at least one staple including a crown fixed to and frangibly separable from the feeder belt, the crown having a first width, and a free end extending from the crown; and at least one pad wider than the first width, wherein each pad is associated with a corresponding crown. An exemplary surgical method using that exemplary apparatus may include placing the feeder belt in proximity to tissue; penetrating the free end of at least one staple into tissue, such that tissue is positioned between the free end and the crown; compressing the free end of at least one staple toward the crown, such that a compressive force is exerted toward the crown; distributing the compressive force across the pad of at least one staple; and shearing at least one staple from the feeder belt. Another exemplary surgical apparatus may include at least one feeder belt having two lateral edges; staples, where each staple includes a first end frangibly connected to a corresponding feeder belt and a second free end; and where the staples form at least one row, each row including at least two staples; and at least one pad, where each pad is located along a corresponding free end of a corresponding staple.

A surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines. The instrument includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator. The implement portion includes a staple cartridge and an anvil. The reciprocating section is adapted to move back and forth along an axis of the implement portion. The movable actuator is associated with the handle portion and is engaged with the drive member such that motion of the actuator causes the drive member to move back and forth between first and second drive positions separated by a first distance. Mechanisms are provided to position only a correct amount of tissue (a predetermined range) between the anvil and cartridge. A multiplier is further provided and is associated with the reciprocating section and the drive member for causing the reciprocating section to move back and forth between first and second reciprocating positions in response to movement of the drive member. The reciprocating section includes a work portion which, when moved distally, effects the firing of staples in the staple cartridge toward the anvil. The work portion is also provided with a reciprocating knife. The first and second reciprocating positions are separated by a second distance which differs from the first distance.

A method for delivering a plurality of individual surgical fasteners includes the steps of providing a surgical fastener delivery device. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The delivery device further includes a plurality of surgical fasteners located between the first and the second members. Next, the surgical fastener delivery device penetrates tissue by moving the drive mechanism distally. A distal end of one of the fasteners is partially deployed by moving the first member proximally. Finally, the distal end of the fastener is fully deployed by moving the second member proximally.

In accordance with the present invention there is provided a surgical fastening instrument. The instrument includes a handle and a shaft extending from the handle. The shaft contains a plurality of surgical fasteners therein. The instrument also has a mechanism for first distally deploying a penetrating member from the distal end of the shaft and thereafter feeding at least one of the surgical fasteners distally from the penetrating member. The instrument further includes a lockout mechanism for preventing the penetrating member from deploying from the shaft upon feeding all of the plurality of surgical fasteners from the shaft.

A delivery device for delivering a plurality of individual surgical fasteners is disclosed. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The device further includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The surgical fasteners are preferably made from a superelastic nickel titanium alloy. Additionally an actuator having at least three sequential positions is included. The first position of the actuator is for moving the drive mechanism distally. The second position is for moving the first member proximally to partially deploy the distal end of the fastener. The third position of the actuator is for moving the second member proximally, to fully deploy the distal end of the fastener.
