  • Publication number: 20240139003
    Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

  • Publication number: 20210227917
    Abstract: The present invention relates to a helmet adaptable to different head shapes. The helmet of the present invention includes a first absorber 200 arranged in the interior of a shell 100, second absorbers 300 arranged in the interior of the first absorber 200, and regulators 400 arranged between the first absorber 200 and the second absorbers 300. When a force acts on the first absorber 200 or one of the second absorbers 300, the corresponding regulator 400 changes the distance between the first absorber 200 and the second absorber 300.

  • Patent number: 6676884
    Abstract: Disclosed is a helmet or a safety cap for protecting the rider's head and a method of manufacturing the same, in which the main body of the helmet has a dual-structure so as to reduce work process when an outer surface of the helmet is painted, and weight thereof. The main body of the helmet has a dual-structure in that an outer surface thereof is formed of a thermoplastic for an aesthetic enhancement and an inner surface thereof is formed of FRP or a mixture of aramide fiber, polyethylene fiber, vinylon, carbon fiber. Thus-formed dual structure of the helmet body contributes to enhancement in impact resistance and convenience in painting, decreasing an overall weight of the helmet.
