Single puncture bifurcation graft deployment system
First Claim
Patent Images
1. A graft deployment system, comprising:
- an elongate, flexible catheter body, having a proximal end and a distal end;
a main vessel graft restraint for restraining a main vessel portion of a graft;
a first branch vessel graft restraint for restraining a first branch vessel portion of the graft; and
a second branch vessel graft restraint for restraining a second branch vessel portion of the graft;
wherein;
the main vessel graft restraint, the first branch vessel graft restraint, and the second branch vessel restraint are arranged in a Y-configuration that is advanced through a first puncture site in a patient'"'"'s vasculature; and
the deployment system is configured such that the main vessel graft restraint, the first branch vessel graft restraint, and the second branch vessel graft restraint are connected to a portion of said graft deployment system to be withdrawn with the graft deployment system through the first puncture site after deployment of the main vessel graft portion of the graft, the first branch vessel portion of the graft, and the second branch vessel portion of the graft.

15. A graft deployment system, comprising:
-
an elongate, flexible catheter body, having a proximal end and a distal end and comprising an outer sheath and an inner core that is axially moveable with respect to the outer sheath and a distal tip positioned adjacent the distal end of the catheter body; a graft having a main vessel portion, a first branch vessel portion, and a second branch vessel portion; and a restraint system configured to restrain the main vessel portion, the first branch vessel portion, and the second branch vessel portion; wherein; the deployment system is configured to be inserted through a first puncture site in a first branch vessel of a patient'"'"'s vasculature; the restraint system comprises a second branch vessel restraint configured to restrain only the second branch vessel portion that is positionable in the second branch vessel; and the restraint system is configured to be completely withdrawn through the first puncture site in the first branch vessel after deployment of the main vessel portion, the first branch vessel portion, and the second branch vessel portion. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
