20160375176 | MINERALIZED COLLAGEN COMPOSITE BONE CEMENTING AND FILLING MATERIAL - To cover shortages of existing PMMA bone cement products, including very high hardness and poor biocompatibility, the invention provides a mineralized collagen incorporated PMMA bone adhesive and filling material. Mineralized collagen (MC) is prepared via an in vitro biomimetic mineralization process and has a chemical composition and structure of self-assembled nano-sized calcium phosphate and collagen molecules, thus possessing biomimetic mineralized structure and mechanical properties similar to natural human bone, good biocompatibility, osteogenic activity and biodegradation ability. An MC incorporated bone adhesive and filling material with high compressive strength and low elastic modulus, and improved biocompatibility compared to pure PMMA bone cements may be obtained. Such bone adhesive and filling materials reduce the risk of abrading the host bone tissue and avoiding damage of the implant caused by extrusion, and form osteointegration with the host bone, improving the stability of the bone adhesive and filling materials at the implantation site. | 12-29-2016 |
20160375180 | METHOD FOR PRODUCING MEDICAL DEVICE AND MEDICAL DEVICE - Provided is a method for preparing a medical device which has a surface lubricating layer on a surface of a substrate and the surface of which exhibits lubricity and antithrombotic qualities when being wet. The method includes forming a coating layer that contains a hydrophilic polymer having at least one reactive functional group selected from the group consisting of an epoxy group, an acid chloride group, and an aldehyde group, and then applying onto the coating layer an antithrombotic material solution that contains an antithrombotic material having a functional group capable of binding to the hydrophilic polymer to form the surface lubricating layer. The concentration of the antithrombotic material in the antithrombotic material solution is more than 0 and less than 0.1 wt %. | 12-29-2016 |
