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.

33. 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. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. An absorbable screw fastener, comprising:
-
a body portion defining a longitudinal axis and having a proximal end and a distal end, the body portion including a center shaft on which is formed a helical thread, the helical thread defining at its outer radius an outer distance and defining an inner distance where the helical thread meets the center shaft, the helical thread including a surface between the inner and outer distances that defines a helical thread slot; and a head portion disposed at the proximal end of the body portion, the head portion having an outer radial surface in which is formed a driver receiving slot, the helical thread slot and the driver receiving slot being longitudinally aligned relative to each other. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

91. A method of performing a surgical procedure, the method comprising the steps of:
-
providing an absorbable screw fastening system, including; a fastener applier having a driver; and a plurality of absorbable screw fasteners arranged longitudinally in series within the fastener applier, each one of the plurality of absorbable screw fasteners including; 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; applying a tip of the fastener driver to a tissue site; and actuating the fastener driver to advance a pilot thereof into the tissue site and to then drive a fastener into the tissue. - View Dependent Claims (92, 93)
