Endovascular docking apparatus and method

A method of providing an apparatus for vascular surgery, comprising:

• providing an external tubular stent graft having a tubular wall and configured to be placed within a sheath in an unexpanded state;
• providing a first tubular structure within the external tubular stent graft and having a tubular wall attached to the tubular wall of the external tubular stent graft, and configured for placement of a graft therein;
• and
• providing a second tubular structure within the external tubular stent graft and having a tubular wall attached to the tubular wall of the external tubular stent graft, and configured for placement of a graft therein.

A method of performing vascular surgery, comprising:

• providing an endovascular dock within a sheath, the endovascular dock comprising:
• an external tubular stent graft having a tubular wall;
• a first tubular structure provided within the tubular wall of the external tubular stent graft;
• and
• a second tubular structure provided within the tubular wall of the external tubular stent graft;
• retracting the sheath to dock the endovascular dock within a wall of a first blood vessel;
• providing a first stent graft having a first end within the first tubular structure and a second end within a wall of a second blood vessel such that blood flow is substantially restricted to within the first stent graft between the first stent graft and the second blood vessel;
• and
• providing a second stent graft having a first end within the second tubular structure and a second end within a wall of a third blood vessel to provide blood flow between the second stent graft and the third blood vessel such that blood flow is substantially restricted to within the second stent graft between the second stent graft and the third blood vessel.

A system for providing an endovascular dock within a blood vessel, comprising:

• an endovascular dock having an external tubular stent graft;
• a first tubular structure provided internally within the external tubular stent graft and configured for placement of a first graft therein;
• a second tubular structure provided internally within the external tubular stent graft and configured for placement of a second graft therein;
• a sheath for housing the endovascular dock within the sheath;
• and
• a top portion connected to a distal end of the sheath;
• wherein the endovascular dock is configured to be placed within a distal end of the sheath in a non-expanded state and is configured to expand when the sheath is retracted from the top portion.
