  • 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.

  • Patent number: 10088412
    Abstract: Provided is an apparatus for analyzing a bio-material. According to an embodiment of the inventive concept, the apparatus may include a light distribution part having grooves, a reflective layer provided on the grooves, and a light emitting part configured to emit light to the light distribution part. The grooves may be recessed from a top surface of the light distribution part, and sidewalls of the grooves may be inclined with respect to the top surface of the light distribution part. The grooves may include a first groove and a second groove. A distance between the light emitting part and the second groove may be greater than that between the light emitting part and the first groove, and a bottom surface of the second groove may be disposed at a level lower than that of a bottom surface of the first groove.

  • Patent number: 7090742
    Abstract: A device for producing inductively coupled plasma and method thereof, wherein a coil is uniformly and dispersedly arranged on a lateral wall in a chamber, instead of the prior device of a permanent magnet mounted on an external wall of the chamber, and the coil is so disposed as to allow a magnetic field formed from the coil to be mutually reinforced at a central portion of the coil, such that charged particles created inside the chamber are effectively isolated relative to the lateral wall of the chamber, thereby enabling to produce plasmas of high density and high uniformity. Intensity and frequency of power source applied to the coil are adjusted to enable to adjust the density and uniformity of plasmas produced in the chamber according to required process characteristics in etching or depositing process using plasmas such that flexibility is provided to the process using the plasmas and design of new process can be free from restriction calling for process chamber configure.
