Abstract:
1. A method for securing an object to bone, the method comprising: using an inserter to position an expandable anchor in a hole formed in a bone; and applying an input force to the inserter from an external source so as to selectively apply an output force to the expandable anchor, whereby to expand the expandable anchor and thereby secure the expandable anchor to the bone; wherein the inserter comprises a force delivery mechanism comprising an input element for receiving the input force from the external source, an output element for selectively applying the output force to the expandable anchor so as to expand the expandable anchor, and a spring-biased connection element for transferring force from the input element to the output element provided that the magnitude of the input force is less than a threshold level, wherein the spring-biased connection element is releasably connected to the input element and secured to the output element, and further wherein the spring-biased connection element is configured to remain connected to the input element when the magnitude of the input force is below the threshold level so as to transfer force from the input element to the output element and to disconnect from the input element when the magnitude of the input force reaches the threshold level so as to not transfer force from the input element to the output element, so that the magnitude of the output force applied to the expandable anchor is limited regardless of the magnitude of the input force applied to the input element.
