    • An implantable medical device (10, 210, 410) for placement in a primary blood vessel having a vessel side branch is disclosed comprising a tubular structure defining an outer surface, a first portion (30, 230, 430) of the outer surface being sized to contact and support the blood vessel on one side of the side branch, and a second portion (34, 234, 434) of the outer surface being sized to contact and support the blood vessel on the other side of the side branch, the tubular structure defining an aperture for alignment with the side branch so as to permit blood flow between the blood vessel and the side branch. The first and second portions are separated across a gap and further include at least one bridging member filament (38, 438) traversing the gap and connecting the first and second portions so as to prevent relative axial separation of the two portions after implantation, the aperture being defined between the bridging member filament and the first and second portions.
    • 公开了一种用于放置在具有脉管侧分支的主血管中的可植入医疗装置(10,210,410),其包括限定外表面的管状结构,外表面的第一部分(30,230,430) 以接触和支撑侧支的一侧上的血管,并且外表面的第二部分(34,234,434)的尺寸设计成接触和支撑侧支的另一侧上的血管,管 结构限定用于与侧支路对准的孔口,以允许血管和侧支路之间的血液流动。 第一部分和第二部分横跨间隙分开,并且还包括穿过间隙并连接第一部分和第二部分的至少一个桥接构件细丝(38,438),以防止植入后两个部分的相对轴向分离,孔 限定在桥接构件细丝与第一和第二部分之间。
