First Claim
Patent Images
1. A method of implanting a device at a target site within an aortic arch adjacent at least one side branch vessel in fluid communication with the aortic arch, the device comprising a main lumen and at least one branched lumen extending laterally therefrom, the method comprising:
- providing a catheter system within which the device has been operatively loaded wherein each of a proximal end and distal end of the main lumen and the free end of the at least one branched lumen is releasably attached to the catheter system;
creating an incision within the vasculature;
advancing the catheter system through the vasculature from the incision to a target site within the aortic arch;
advancing the distal end of the main lumen from a distal end of the catheter system wherein the distal end of the main lumen remains releasably attached to the system within the aortic arch;
advancing the free end of the at least one branched lumen from a distal end of the catheter system into the side branch vessel while the main lumen remains within the aortic arch and wherein the free end remains releasably attached to the catheter system wherein tension applied to the distal end of at least one side branch luminal end elongates the at least one side branch lumen during advancement into the side branch vessel and where controlling the tension allows expanding and maintaining the side branch lumen in a partially deployed state prior to releasing from the catheter system into a fully deployed state;
detaching at least one of the advanced luminal ends from the system to implant the device.

Abstract
The present invention provides systems and methods for deploying implantable devices within the body. The delivery and deployment systems include at least one catheter or an assembly of catheters for selectively positioning the lumens of the implant to within target vessels. Various deployment and attachment mechanisms are provided for selectively deploying the implants.

8. A method of implanting a device at a target site within the body having a main vessel and at least one laterally extending side branch vessel in fluid communication with the main vessel, where the device includes a main lumen and at least one side-branch lumen extending therefrom, the method comprising:
-
providing a catheter system within which the device is operatively loaded wherein each of a proximal end and distal end of the main lumen and the free end of the at least one branched lumen is releasably attached to the catheter system; creating an incision within the vasculature; advancing the catheter system through the vasculature from the incision to a target site within the main vessel; advancing the distal end of the main lumen from a distal end of the catheter system wherein the distal end of the main lumen remains releasably attached to the system within the main vessel; advancing the free end of the at least one branched lumen from a distal end of the catheter system from the main vessel and adjacent to the main lumen laterally into the side branch vessel while the main lumen remains within the main vessel and wherein the free end remains releasably attached to the system, wherein tension applied to the distal end of at least one side branch luminal end elongates the at least one side branch lumen during advancement into the side branch vessel and where controlling the tension allows expanding and maintaining the side branch lumen in a partially deployed state prior to releasing from the catheter system into a fully deployed state; and detaching at least one of the advanced lumenal ends from the system to implant the device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of implanting a device at a target site within the body having a main vessel and at least one laterally extending side branch vessel in fluid communication with the main vessel, where the device includes a main lumen and at least one side-branch lumen laterally extending therefrom, the method comprising:
-
providing a catheter system within which the device is operatively loaded wherein each of a proximal end and distal end of the main lumen and the free end of the at least one side-branch lumen is releasably attached to the catheter system; creating an incision within the vasculature; advancing the catheter system through the vasculature from the incision to a target site within the main vessel; advancing the distal end of the main lumen from a distal end of the catheter system wherein the distal end of the main lumen remains releasably attached to the system within the main vessel; deflecting the free end of the at least one side-branch lumen from a distal end of the catheter system from the main vessel and adjacent to the main lumen into the side branch vessel while the main lumen remains within the main vessel where the ability of the device to adjust location and position of the main and side branch lumens allows the side branch lumen to accommodate the laterally extending side branch vessel and wherein the free end remains releasably attached to the system; controlling tension applied to the distal end of at least one side branch luminal end to elongate the at least one side branch lumen during insertion into the side branch vessel and where controlling the tension allows expanding and maintaining the side branch lumen in a partially deployed state prior to releasing from the catheter system into a fully deployed state; and detaching at least one of the advanced lumenal ends from the system to implant the device. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
