1. A system for repair of vasculature, comprising:
- an elongate member having a superior portion and an inferior portion and at least one lumen therethrough, the superior portion having a superior tip with reduced diameter;
a repair device mounted near the superior portion of the elongate member and having means for anchoring the repair device in vasculature;
a jacket coaxially disposed about the elongate member; and
means for varying the flexibility of the elongate member, the means extending to the superior tip of the elongate member and including structure providing a particular point along the elongate member with alternatively a first flexibility and a second flexibility; and
means for releasably attaching the jacket to the elongate member such that relative movement is precluded.

15. A system for repair of vasculature, comprising:
-
an elongate member having a superior portion and an inferior portion and at least one lumen therethrough, the superior portion having a superior tip with reduced diameter; a repair device mounted near the superior portion of the elongate member and having means for anchoring the repair device in vasculature; a jacket coaxially disposed about the elongate member; and a hypotube slidably disposed within the elongate member, the hypotube extending to the superior tip of the elongate member such that moving the hypotube relative to the elongate member varies the flexibility of the elongate member and provides a particular point along, the elongate member with alternatively a first flexibility and a second flexibility and wherein the elongate member comprises a second hypotube fixedly attached to the superior portion.

16. A system for repair of vasculature, comprising:
-
an elongate member having a superior portion and an inferior portion and at least one lumen therethrough, the superior portion comprising a molded tip with an SST tube inserted therein, the SST tube having a superior end with a reduced diameter tip and an inferior portion having a stop ring and jacket guard; a first hypotube permanently attached to the inferior portion of the SST tube; a repair device releasably attached near the superior portion of the elongate member by a release wire and having means for anchoring the repair device in vasculature; a jacket coaxially disposed about the elongate member; and a second hypotube slidably disposed within the first hypotube, the second hypotube extending into the SST tube reduced diameter tip and attached to a slider mechanism at the inferior portion of the elongate member such that the second hypotube may be moved longitudinally relative to the elongate member.

17. A system for repair of vasculature, comprising:
-
an inner member having a superior portion and an inferior portion and at least one lumen therethrough, the superior portion of the inner member being highly flexible; a repair device mounted at the superior portion of the inner member and having means for anchoring the repair device in vasculature; at least one steering ring coaxially attached at the superior portion of the inner member distal the repair device anchoring means, the at least one steering ring having a center aperture therethrough; a plurality of steering wires attached to the at least one steering ring such that manipulating the steering wires causes the superior portion of the inner member to bend; an outer member having a superior portion and an inferior portion and coaxially disposed over at least a portion of the inner member; means for manipulating the steering wires; and a jacket coaxially disposed about the inner member- and outer member, the jacket having a superior end and an inferior end. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A system for repair of vasculature, comprising:
-
an inner member having a superior portion and an inferior portion with at least one lumen therethrough, the superior portion of the inner member being highly flexible; a repair device mounted at the superior portion of the inner member and having means for anchoring the repair device in vasculature; a plurality of steering rings coaxially attached to the inner member distal the repair device anchoring means, the most proximal steering ring having a plurality of steering wires attached thereto; means for causing the plurality of steering rings to bend in unison when the steering wires are manipulated such that manipulating the steering wires causes the superior portion of the inner member to bend in both the horizontal and vertical planes; an outer member coaxially disposed over at least a portion of the inner member;
means for manipulating the steering wires; anda jacket coaxially disposed about the inner member and outer member.

44. A method of repairing vasculature, comprising:
-
providing a catheter having an inner member coaxially disposed within an outer member, the superior portion of the inner member being highly flexible and having a repair device mounted thereon, the repair device having means for anchoring in vasculature, at least one steering ring coaxially attached to the inner member, the at least one steering ring having a plurality of steering wires attached thereto, and means for manipulating the steering wires such that manipulating the steering wires causes the superior portion of the inner member to bend;
advancing the catheter in vasculature such that the anchoring means of the repair device is adjacent a repair site;manipulating the steering wires to position the anchoring means of the repair device;
deploying the anchoring means of the repair device. - View Dependent Claims (45)
