One example of a surgical apparatus may include at least one resorbable feeder belt, and a plurality of staples fixed to that feeder belt. Another example of a surgical apparatus may include at least one feeder belt and at least one resorbable carrier detachably connected to a corresponding feeder belt, where the carrier includes a plurality of staples attached to it. An exemplary surgical method of treating tissue within the body of a patient may include providing a surgical instrument that includes an end effector moveable between an open configuration and a closed configuration, where the end effector includes an anvil and a staple holder pivotally connected to one another, where the anvil holds a knife; and at least one resorbable feeder belt and a plurality of staples fixed to the feeder belt, where the feeder belt extends into said staple holder; placing the end effector in proximity to tissue; deploying a plurality of staples into tissue; separating a distal segment of at least one feeder belt from a remainder of that feeder belt; and leaving that distal segment within the body of the patient.
