  • Flexible stent-graft
    Patent number: 8998972
    Abstract: A stent graft is provided which has two stent sections having different functions on, for example, a tubular graft. One stent section preferably comprises a plurality of circumferential reinforcing hoops and the other a Z-stent. The two sections are preferably separated by a spacer section and the tubular graft preferably increases in diameter from the Z-stent section to the hooped section. This enables the stent graft to be compressed radially so that it can be inserted in a catheter for later delivery to a body lumen.
