1. An absorbable screw fastener, comprising:
- a body portion defining a longitudinal axis and having a proximal end and a distal end, the body portion having a helical thread formed thereon, the helical thread having a major diameter and a minor diameter; and
a head portion disposed at the proximal end of the body portion, the head portion having a driver receiving slot formed in an outer radial surface of the head portion, the helical thread having a helical thread slot corresponding to and in alignment with the driver receiving slot, wherein a radially-innermost surface of the helical thread slot is between the major diameter and the minor diameter of the helical thread.

Abstract
An absorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion. The head portion includes a driver receiving configuration on its outer surface. The screw fastener further includes a cannulated center lumen with an opening extending from the head portion through the longitudinal length of the body portion.
