Abstract
The longitudinal implant is fastened to bones on either side of a damaged area through a connecting device. Said implant is comprised of a filament or fiber composite material and said connecting device is made of a material harder than said longitudinal implant. The longitudinal implant is preferably made of a carbon filament composite material, wherein the filament are encapsulated in a polymer matrix.
Claims6
A longitudinal implant and connecting device wherein said longitudinal implant is fastenable to bones on either side of a damaged area through said connecting device, said implant and connecting device comprising:
- a longitudinal implant made of a filament or fiber composite material, wherein filaments or fibers in said material are oriented to resist biomechanical forces, and
- a connecting device made of a material harder than said longitudinal implant,
- wherein, said connecting device is operative to squeeze and lock the longitudinal implant into position both by depression caused by a squeezing and increased friction between the harder material of the connecting device and the composite material of the longitudinal implant, and
- wherein the implant is a rod or a rail, the rod or rail formed without any openings or slots, wherein filaments or fibers are aligned lengthwise, so that compression will not change their strength characteristics to any extent even when compressed, and
- wherein the rod or rail is formed without any recesses, bevels, or slants, and
- wherein the filaments are woven, comprising first filaments that are oriented in the axial direction of the implant, and second filaments that are oriented perpendicular to the axial direction of the implant.
