Patent ID: 7819897

Claim:
A fastener configurable for delivery through a tube for positioning a prosthetic component adjacent an anatomical support, said fastener comprising: a linking rod defining a linking rod longitudinal axis interconnecting an anchoring element having a proximal end, a distal end, and defining an anchoring element longitudinal axis and an immobilizing element having a proximal end, a distal end, and defining an immobilizing element longitudinal axis such that said fastener can adopt at least a non-stressed configuration wherein the anchoring element longitudinal axis intersects the immobilizing element longitudinal axis, said fastener also configured to adopt a maximum stress configuration wherein said linking rod longitudinal axis, anchoring element longitudinal axis and immobilizing element longitudinal axis are substantially parallel to one another, the linking rod being connected to the anchoring element at a first intermediate location between the proximal and distal ends of the anchoring element and to the immobilizing element at a second intermediate location between the proximal and distal ends of the immobilizing element.
