1. An implant delivery system for use within a vessel or tubular structure within the body, the system comprising:
- an implant having a distal end and a proximal end defining a length there between and having a diameter;
a first catheter configured for slidable retention of the implant therein where the proximal end of the implant is releasably connected to the first catheter through an intermediate member located within the first catheter;
at least one string releasably coupled to a first free end of the implant;
a second catheter configured for removable attachment to the at least one string, where the string allows for controlling and releasably attaching the first free end of the implant to the second catheter;
wherein the first and second catheters are in substantial co-axial alignment with each other upon attachment of the at least one string to the second catheter, such that the first and second catheters stretch the implant in a reduced diameter, and relative axial movement between the first and second catheter in a first direction unstretches and expands the implant to cause partial deployment of the implant within the vessel or tubular structure and relative axial movement between the first or second catheter in a second direction restretches the implant for repositioning;
where when the implant is partially sheathed in the first catheter, an unsheathed portion of the implant is selectively expandable and contractible;
where detachment of the at least one string from the implant causes full expansion and deployment of the free end of the implant from the second catheter; and
where the intermediate member is in substantial co-axial alignment with the first and second catheters.

Abstract
The present invention provides devices and methods for fabricating and deploying an implantable device within the body. The invention is particularly suitable for delivering and deploying a stent, graft or stent graft device within a vessel or tubular structure within the body, particularly here the implant site involves two or more interconnecting vessels. The delivery and deployment system utilizes a plurality of strings which are releasably attached to the luminal ends of the implantable device.

10. An implant delivery system for use within a vessel or tubular structure within the body, the system comprising:
-
an implant having a distal end and a proximal end defining a length there between and having a diameter, where the implant comprises a main lumen and a side branch lumen; a first catheter configured for slidable retention of the implant therein where the proximal end of the implant is releasably connected to the first catheter through an intermediate member located within the first catheter; at least one string releasably coupled to a first free end of the implant; a second catheter configured for removable attachment to the at least one string, where the string allows for controlling and releasably attaching the first free end of the implant to the second catheter; wherein the first and second catheters are in substantial co-axial alignment with each other upon attachment of the at least one string to the second catheter, such that the first and second catheters stretch the implant in a reduced diameter, and relative axial movement between the first and second catheter in a first direction unstretches and expands the implant to cause partial deployment of the implant within the vessel or tubular structure and relative axial movement between the first or second catheter in a second direction restretches the implant for repositioning; where the relative axial movement between the first and second catheter in the first direction causes the diameter of the implant to increase; where the relative axial movement between the first or second catheter in the second direction causes the diameter of the implant to decrease; where when the main lumen is partially sheathed in the first catheter, the side branch lumen is positionable in a side branch vessel; and where detachment of the at least one string from the implant causes full expansion and deployment of the free end of the implant from the second catheter. - View Dependent Claims (11, 12, 13, 14, 15)

-
