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 the a distal end of the catheter is positioned within the side branch lumen; and
a string extending through the at least one catheter lumen and releasably attached to a distal end of the side branch lumen, wherein, prior to release of the string 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.

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.

6. 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 the catheter lumen is adapted for receiving the stent in a reduced profile; and a pin assembly engaging apices of a distal end of the main lumen wherein the pin assembly is spring-loaded wherein, upon release of the spring-load, the pin assembly releases the apices.

7. A system for delivering and deploying a stent having a distal end and a proximal end and a structure therebetween wherein the structure having an initial profile which is reducable along a length of the structure, the system comprising:
-
a catheter having an inner diameter less than a diameter of the stent in the initial profile, the catheter adapted for receiving the stent in a reduced profile; and a lumen comprising a port for receiving a fluid and at least one gasket distal of the port prevent leakage of the fluid from the port, wherein at least a portion of the catheter is flushed by passage of the fluid therethrough.

8. A sheath adapted for endovascular delivery of catheters, the sheath comprising:
-
a braided material embedded within a wall of the sheath and extending along a length of tile sheath; and at least one solder joint within the braided material. - View Dependent Claims (9)

10. A stent-loaded catheter assembly comprising:
-
a catheter sheath having at least one lumen and at least one radiopaque marking; and a stent device 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 the catheter lumen is adapted for receiving the stent device in a reduced profile; and the stent device further having at least one selectively positioned radiopaque marking, wherein alignment of the radiopaque marking on the stent device with the radiopaque marking on the catheter sheath validates proper loading of the stent device within the catheter sheath. - View Dependent Claims (11, 12)
