Compliant osteosynthesis fixation plate
First Claim
1. A bendable polymer tissue fixation device for implantation into a living body, said polymer fixation device comprising a laminar body having an first layer, a second layer and an interface, said first layer comprising a porous form of a polymer material, said second layer comprising a non-porous form of said polymer material;
- said polymer material comprising a biopolymer, said porous form transitioning to the non-porous form at said interface, wherein at least at room temperature and within a period of time that is from prior to said implantation up through said implantation, said laminar body possesses the following properties;
being capable of being smoothly bent upon application of a bending force, the bending force permanently collapsing a portion of the pores of the porous form to prevent cracking or breaking of the non-porous form, and said laminar body maintaining said bent condition following removal of the bending force.

Abstract
A bendable polymer tissue fixation device suitable to be implanted into a living body, comprising a highly porous body, the porous body comprising a polymer, the porous body comprising a plurality of pores, the porous body being capable of being smoothly bent, wherein the bending collapses a portion of the pores to form a radius curve, the polymer fixation device being rigid enough to protect a tissue from shifting. In a preferred embodiment the polymer fixation device may be capable of being gradually resorbed by said living body. In one embodiment, the polymer fixation device comprises a plurality of layers distinguishable by various characteristics, such as structural or chemical properties. In another embodiment, the polymer fixation device may comprise additional materials; the additional materials serving to reinforce or otherwise alter the structure or physical characteristics of the device, or alternatively as a method of delivering therapy or other agents to the system of a living being.
