SURGICAL FASTENERS AND FASTENING DEVICES

摘要

The invention provides a surgical fastener. The fastener has a first element defining an axis of the fastener, and or more prongs attached to the first element at hinge regions. Deploying the fastener involves bending the prongs at the hinges so as to increase the distance of the prong tips from the axis and locking the fastener in this deployed configuration. The invention also provides a surgical fastening device and a method for attaching a surgical fastener to a site of a body tissue.
