Claim Text:
1. A polymer tissue fixation device for implantation into a living body, said polymer fixation device comprising a laminar body having a first layer, a second layer and an interface, said first and second layers and said interface all comprising a biopolymer material, wherein said first layer has a greater porosity than said second layer; said first layer transitioning to the lower porosity second layer 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 higher porosity first layer to prevent cracking or breaking of the lower porosity second layer, and said laminar body maintaining said bent condition following removal of the bending force.
