Patent ID: 8828066

Claim:
An dual end expandable implant attachment assembly, comprising: A one-piece elongated hollow body with expandable skirts at both ends of the elongated hollow body; A draw screw having a head captured within a proximal end of the hollow body and a threaded shank connected to the head and which extends to a distal end of the hollow body; The head of the draw screw is flared, whereby rotation of the draw screw through the inner cavity of the hollow body causes radial movement of the expandable skirts at the proximal end of the hollow body from the first retracted position to the second expanded position; and At the end of the threaded shank of the draw screw, located partially inside the distal end of the hollow body, is a flared expansion nut having a skirt-engaging side wall and an inner threaded cavity into which the shank of the draw screw is threaded, whereby rotation of the draw screw through the inner cavity of the expansion nut causes the expansion nut to move furtherinside the distal end of the elongated hollow body forcing radial movement of the expandable skirts at the distal end of the hollow body from the first retracted position to the second expanded position.
