  • Publication number: 20200086011
    Abstract: An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.

  • Patent number: 10507444
    Abstract: A method and a device for producing honeycomb particles capable of absorbing harmful molecular elements are disclosed. A chemical element having a crystal structure is dissolved in water in a certain percentage to form a chemical element solution, and then it is pressurized. The pressurized chemical element solution is sprayed out in mist form toward a forming mirror by a high-pressure nozzle of a spray tube. When the chemical element solution in mist form contacts the heated forming mirror, the moisture quickly bursts and evaporates to form fine particles. The dried fine particles of the chemical element are made to fall by the high frequency vibration and are collected. Accordingly, the chemical element having a crystal structure is formed into fine particles having many air holes, increasing the area for chemical reaction and further increasing the efficiency of absorption of harmful elements such as various toxic elements or bacteria.
