Abstract
A surgical fastener system includes a plurality of fasteners having a throughbore with a non-circular cross section portion. The fasteners may engage with a splined mandrel that passes through the throughbore of the fasteners and rotates the fasteners relative to the mandrel to move at least one of the fasteners along the mandrel, e.g., along the mandrel's longitudinal axis. A distal end of the mandrel may be inserted into a material, such as a tissue, prosthetic or other, and a fastener may be deployed from the distal end of the mandrel while the distal end is positioned in the material.
Claims18
A surgical fastener comprising:
- a barrel portion including a helical thread extending from near a distal end of the barrel portion toward a proximal end of the barrel portion;
- a head portion at the proximal end of the barrel portion;
- and
- a throughbore extending through the head portion and the barrel portion, the throughbore including a splined portion near the distal end of the barrel portion and a non-splined portion near the proximal end of the barrel portion;
- wherein the barrel portion and head portion are formed of a bioabsorbable material.
A surgical fastener comprising:
- a barrel portion including a helical thread extending from near a distal end of the barrel portion toward a proximal end of the barrel portion, the distal end of the barrel portion including a crenellated tip;
- a head portion at the proximal end of the barrel portion;
- and
- a throughbore extending through the head portion and the barrel portion, the throughbore including a non-circular portion arranged to engage with a driver mandrel;
- wherein the barrel portion and head portion are formed of a bioabsorbable material.
