1. An intraluminal device for use at a vessel bifurcation, the device comprising:
a midsection; a tail coupled to the midsection and configured to permit pushing and pulling of the device within a catheter; and first and second stents each comprising a plurality of filaments coupled together at the midsection to form respective first and second proximal regions, the first and second stents extending separately from the midsection towards respective first and second distal regions, the first and second stent distal regions comprising respective first and second bioabsorbable couplings, wherein in a gathered configuration, (i) the plurality of filaments of the first stent converge to the first bioabsorbable coupling at the first distal region, and (i) the plurality of filaments of the second stent converge to the second bioabsorbable coupling at the second distal region, the first and second distal regions being configured to flex away from each other during expansion of the first and second stents from a compressed state to an expanded state, and wherein, upon bioabsorption of the first and second couplings, the first and second distal regions are expandable from the gathered configuration to a released configuration such that the pluralities of filaments at the first and second distal regions radially diverge for permitting normal blood flow through the bifurcation, and wherein the first and second stents alone support the device within efferent vessels of the bifurcation without the tail engaging an afferent vessel of the bifurcation. |
