20090157194 | IMPLANT COMPOSITE MATERIAL - An implant composite material is provided which is for use in the treatment of articular cartilage disorders such as hip joint femur head necrosis and knee joint bone head necrosis, the reconstruction/fixing of a bio-derived or artificial ligament or tendon, the uniting/fixing of a bone, etc. Part of the implant composite material is replaced by bone tissues in an early stage to enable the material to stably bond with a living bone, while the other part retains a necessary strength over a necessary time period. Finally, the implant composite material is wholly replaced by the living bone and disappears. | 06-18-2009 |
20100331986 | BIOMATERIAL FOR ARTIFICIAL CARTILAGE - A biomaterial for an artificial cartilage is disclosed. The biomaterial eliminates the risk of possible adverse effects due to scattering of fragments of the biodegradable and bioabsorbable polymers and shows enhanced adhesiveness which allows more solid adhesion of the artificial cartilage to vertebral bodies and the like. The biomaterial includes an organized structure comprising organic fibers arranged in one of a multiaxial three-dimensional woven or knitted structure having three or more axes and a combined structure of the woven structure and the knitted structure; and a biodegradable and bioabsorbable pin provided inside the organized structure. | 12-30-2010 |
20120114733 | IMPLANT MATERIAL AND PRODUCTION METHOD THEREOF - The present invention provides an implant material comprising an organic-inorganic complex porous article and a production method thereof. The organic-inorganic complex porous article is a biodegradable and bioabsorbable bioactive porous article in which a bioactive bioceramics powder is uniformly dispersed in a biodegradable and bioabsorbable polymer, wherein it has continuous pores and the bioceramics powder is partly exposed to the pore inner surface or the pore inner surface and the porous article surface. | 05-10-2012 |

20130013074 | STAND-ALONE BIOMIMETIC ARTIFICIAL INTERVERTEBRAL DISC SYSTEM - The artificial intervertebral disc of the present invention includes: a structured fabric having biomimetic structure and dynamic behavior, the structure comprising organic fibers, which are formed to be a cubic multi-axial three-dimensional fabric having tri-axial, to be interwoven tissues or to be a complex tissue of these; and tappets mounted on the upper surface and the lower surface of this structured fabric, wherein the tappets are connected and fitted with the connecting filaments vertically penetrating through the structured fabric. This structured fabric shows biomimetic dynamic behavior like a real intervertebral disc and achieves a clinically effective and reliable stand-alone type of biomimetic artificial intervertebral disc which can be inserted and fixed with minimally-invasive operation. | 01-10-2013 |
20130209765 | REINFORCED COMPOSIT THAT IS COMPLEMENTARILY REINFORCED AND PRODUCTION METHOD THEREFOR - The forging-reinforced composite constructed of a plurality of different kinds of materials, which have compatible polymers comprising crystalline and glass phases at room temperature for the matrices, is a composite, wherein, by being forged in a layer-separated state in which each of the different kinds of materials forms micron-sized fibrous layers that crossed and intermingled three-dimensionally with each other and the arrangement of the crystals in the crystalline phases configuring the matrices having a disordered orientation without anisotropy in a variety of directions, the inherent-properties of the material of each layer are complementarily reinforced. A mixed nonwoven fabric wherein microfibers are crossed and intermingled two- or three-dimensionally with each other is manufactured and heated under pressure at or above the melting point of the polymers to manufacture compact blocks wherein the microfibers are welded. Then, the compact blocks are forged at a crystallization temperature. | 08-15-2013 |
