Patent ID: 7942905

Claim:
A system for flexibly stabilizing a first vertebra with respect to a second vertebra, the system comprising: a dynamic device comprising a first attachment portion, a second attachment portion, and a resilient member positioned between the first attachment portion and the second attachment portion, wherein the first and second attachment portions compress the resilient member when the first and second attachment portions move towards each other and compress the resilient member when the first and second attachment portions extend away from each other, wherein the first attachment portion includes a first flange adapted to transfer a first force to a first surface of the resilient member and wherein the second attachment portion includes a second flange adapted to transfer a second force to a second surface of the resilient member; a first fixation member for connecting the first attachment portion to the first vertebra; a second fixation member for connecting the second attachment portion to the second vertebra; and a first rod member connected to the first attachment portion, the first rod member having a third flange adapted to transfer a first tensile force to the second surface of the resilient member.
