Surgical fasteners and methods and devices for deploying a surgical fastener

摘要

Various exemplary surgical fasteners are provided, and methods and devices are provided for deploying a surgical fastener. In general, the methods and devices allow a surgical fastener to be deployed to secure tissue to bone. In one embodiment, a surgical fastener can be configured to move between a first linear or compressed configuration, in which the fastener can have a first maximum diameter, and a second bent or expanded configuration, in which the fastener can have a second maximum diameter greater than the first maximum diameter. A delivery device can be configured to advance the fastener through tissue and into bone to attach the tissue to the bone. The delivery device can be configured to maintain the fastener in the compressed configuration such that when the fastener is released from the delivery device, the fastener can be configured to self-expand from the compressed configuration to the expanded configuration.

主权项

1. A surgical method, comprising:
positioning a distal end of a cannula adjacent to a tissue overlying a bone; advancing a first leg of a fastener from the distal end of the cannula to drive the first leg through the tissue and into the bone; after advancing the first leg, repositioning the distal end of the cannula laterally relative to a longitudinal axis to the cannula and relative to the tissue; and after repositioning the distal end of the cannula, advancing a second leg of the fastener from the distal end of the cannula to drive the second leg through the tissue and into the bone, thereby attaching the tissue to the bone.
