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.
A polymer tissue fixation device for implantation into a living body, said polymer fixation device (i) comprising a porous body comprising at least one biopolymer and a plurality of pores, and (ii) being gradually resorbable by said living body, wherein at least at room temperature and within a zone of time that is defined by being from prior to said implantation up through said implantation, said porous body inherently possesses the property of being smoothly bent upon being subjected to a bending force, said bending force at least partially but irreversibly collapsing a portion of the pores to form a radius curve, whereby said porous body (a) inherently maintains said radius curve upon removal of the bending force, and (b) is rigid enough to protect a tissue attached to said device from shifting.
A bendable polymer tissue fixation device for implantation into a living body, said polymer fixation device (i) comprising a composite comprising a porous body defining a plurality of pores, and at least one strengthening agent contained within said porous body, and (ii) being capable of being resorbed by said living body, wherein at least at room temperature and within a period of time that is from prior to said implantation up through said implantation, said porous body intrinsically possesses the characteristics of being capable of being smoothly bent upon exposure to a bending force, said bending collapsing a portion of the pores to form a radius curve, whereby said porous body (a) maintains said radius curve upon removal of the bending force, and (b) is rigid enough to protect a tissue fixed to said device from shifting.
A deformable polymer tissue fixation device for implantation into a living body, said polymer fixation device (a) comprising a porous body comprising at least one biopolymer and a plurality of porous zones, and (b) is resorbable by said living body, wherein at least at room temperature and from prior to said implantation up through said implantation, said porous body inherently possesses the properties of:
