  • Publication number: 20240082027
    Abstract: A distal aortic stent graft assembly including a main body having a proximal end and a distal end. The main body defines a peripheral opening. The proximal end defines a proximal opening. The distal end defines a distal opening. The proximal opening and the distal opening are configured to perfuse blood through the main body when the main body is in a deployed state. The distal aortic stent graft assembly further includes a coupling extending radially from the main body and corresponding to the opening in the main body. The coupling is configured to align with a blood vessel and perfuse blood through the coupling when the coupling is in the deployed state.

  • Patent number: 8398749
    Abstract: A process for the recovery of carbon dioxide, which includes: (a) an absorption step of bringing a carbon dioxide-containing gaseous feed stream into gas-liquid contact with an absorbing fluid, whereby at least a portion of the carbon dioxide present in the gaseous stream is absorbed into the absorbing fluid to produce (i) a refined gaseous stream having a reduced carbon dioxide content and (ii) an carbon dioxide-rich absorbing fluid; and (b) a regeneration step of treating the carbon dioxide-rich absorbing fluid at a pressure of greater than 3 bar (absolute pressure) so as to liberate carbon dioxide and regenerate a carbon dioxide-lean absorbing fluid which is recycled for use in the absorption step, in which the absorbing fluid is an aqueous amine solution containing a tertiary aliphatic alkanol amine and an effective amount of a carbon dioxide absorption promoter, the tertiary aliphatic alkanol amine showing little decomposition under specified conditions of temperature and pressure under co-existence with
