Abstract
A delivery system and method for a self-expandable implantable device are provided. The system includes an inner tube, an outer tube and an intermediate tube, wherein the outer tube is designed to be pulled proximally with respect to the intermediate and inner tubes, thereby releasing the implantable device. The system further includes a deployment sleeve with ridges for containment of the diverter, and an elliptical tip for insertion into a blood vessel. The system includes an ellipsoidal tip, which in one embodiment is mechanically connected to the inner tube. The implantable device comprises a diverter stent or graft.

58. A method for positioning an implantable device within a body lumen, the method comprising:
-
providing a delivery system having an inner tube, an intermediate tube at least partially covering said inner tube, an outer tube enclosing said inner tube and said intermediate tube, and an implantable device between said inner and outer tubes;
inserting said delivery system into the body lumen; and
pulling said outer tube proximally with respect to said inner tube so as to release the implantable device. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 59, 60, 61, 62, 63, 64, 67)

65. A method for preventing entanglement of an implantable devicewithin a delivery system, the method comprising:
-
providing a delivery system having an inner tube having a diverter positioned on the inner tube and a stopper positioned on the inner tube proximal to said implantable device, having an outer tube positioned over the inner tube, and further having an intermediate tube attached to the inner tube, wherein a distal end of the intermediate tube at least partially covers the stopper; and
sliding the intermediate tube distally with respect to said outer tube so that the distal end of the second tube flares outward over the stopper, thereby coming in contact with the outer tube and forming a divider between the implantable device and a proximal portion of the delivery system. - View Dependent Claims (66)

68. A method for positioning an implantable device within a delivery system, the method comprising:
-
providing a sleeve with indentations on a distal end of an inner tube;
placing the implantable device at least partially on the sleeve wherein part of the implantable device sits within the indentations; and
providing an outer tube to enclose the implantable device and the inner tube. - View Dependent Claims (69, 70, 71)
