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.

Claims

1. A system for delivering and deploying an implant within a vessel or tubular structure within the body, the implant having a distal end and a proximal end defining a length therebetween and having a diameter, the system comprising:

a first catheter configured for slidable retention of the implant therein;

at least one string adapted for releasable attachment to the implant;

a second catheter configured for removable attachment to the at least one string;

wherein the first and second catheters are in substantial axial alignment with each other upon attachment of the at least one string to the second catheter.

2. The system of claim 1 further comprising a guide wire over which both of the catheters are trackable.

3. The system of claim 2 further comprising at least a second guidewire to which an end of the implant is releasably attached.

4. The system of claim 1, wherein the implant further comprises a main lumen along the length and at least one side branch lumen extending from the main lumen and having a distal end, wherein the at least one string is adapted for releasable attachment to the distal end of the at least one side branch lumen.
