摘要 |
A balloon-expandable shunt is disclosed for shunting a vessel which has a graft with two ends and at least one expandable support element supporting the graft from within along a length at or near at least one of its ends. The shunt is bifurcated at an aperture that leads to a side-channel and which has a closed configuration and an open configuration such that when the aperture is in the closed configuration it defines a clot-resistant inner graft surface and when the aperture is in the open configuration it is configured to provide access to the shunt for a balloon that actuates the expandable support element. A balloon configured for actuating the shunt is also disclosed. A kit has a bifurcated graft with at least one expandable support element and a balloon for actuating the at least one expandable support element. |

1. A balloon expandable shunt for shunting a disrupted vessel, comprising:
a graft defining a first lumen having an expanded-state diameter and extending between first and second ends of the graft; at least one expandable support element supporting a length of the graft from within near at least one of said first and second ends; a side channel defining a second lumen and configured to receive a balloon for actuating the at least one expandable support element; a bifurcation at a portion of the graft defined by an intersection of the first lumen and the second lumen; and an elongate aperture in the graft circumscribing the bifurcation and having a substantially closed configuration and a substantially open configuration such that when the aperture is in the substantially closed configuration it defines a clot-resistant inner graft surface and when the aperture is in the substantially open configuration it is configured to provide access to the first lumen for a balloon for actuating the at least one expandable support element. |
