1. A stent-loaded catheter assembly comprising:
- a catheter having at least one lumen; and
a stent comprising a main lumen having a proximal end and a distal end and at least one side branch lumen connected to and extending laterally from the main lumen, wherein a distal end of the catheter is positioned within the side branch lumen where a distal end of the side branch lumen comprises a plurality of apices; and
an elongated member extending through the at least one catheter lumen, the elongated member exiting at the distal end of the catheter and extending through the plurality of apices of the distal end of the side branch lumen before returning into the distal end of the catheter to releasably compress and attach the distal end of the side branch lumen to the distal end of the catheter, wherein, prior to release of the elongated member from the side branch lumen, selective movement of the catheter at a proximal end results in a corresponding pivotal movement at the distal end wherein the catheter distal end is steerable wherein the selective movement is rotational and the pivotal movement is lateral.

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 stent-loaded catheter assembly comprising:
-
a stent having a side branch stent; a catheter adapted for receiving the stent in a reduced profile; an elongated member extending through the catheter and exiting at a distal end of the catheter, the elongated member extending through a plurality of apices of a distal end of the side branch stent before returning into the distal end of the catheter to releasably compress and attach the distal end of the side branch stent to the distal end of the catheter; a handle portion coupled to the catheter; and a lumen extending within a body of the catheter through the handle portion and comprising a port for receiving a fluid and at least one gasket distal of the port and within the handle portion to prevent leakage of the fluid from the port, wherein at least a portion of the catheter is configured to be flushed by passage of the fluid therethrough. - View Dependent Claims (9, 10, 11)

12. A stent-loaded catheter assembly comprising:
-
a catheter having at least one lumen; and a stent comprising a main lumen having a proximal end and a distal end and at least one side branch lumen connected to and extending laterally from the main lumen, wherein a distal end of the catheter is positioned within the side branch lumen; and an elongated member extending through the at least one catheter lumen releasably attached to at least one apex of the side branch lumen, wherein, prior to release of the elongated member from the side branch lumen, movement of the catheter at a proximal end results in a corresponding movement at the catheter distal end, and wherein the catheter distal end is steerable via the elongated member. - View Dependent Claims (13, 14, 15, 16)
