ANCHOR DEVICE FOR USE WITH CATHETERS
First Claim
1. An anchor device for use with catheters, the anchor device comprising:
- an anchor stent formed from a plurality of wire elements, each wire element in the plurality of wire elements having a zig-zag pattern shape,wherein at least one end of a first wire element in the plurality of wire elements is attached to at least one end of a second wire element adjacent to the first wire element, andwherein the anchor stent further includes a first expandable stent segment having a first expanded width, and a second expandable stent segment having a second expanded width different from the first expanded width;
a plurality of connector struts, each connector strut having a first end attached to one of the wire elements of the anchor stent, and an opposite second end coalescing to form a strut tip; and
a guide device attached to the anchor stent at the strut tip.

Abstract
An anchor device to simplify catheterization procedures, particularly for insertion and maneuvering of large catheters in tortuous arteries, vessels, or other lumen is disclosed. In some embodiments, the anchor device includes an anchor stent formed from a plurality of zig-zag shaped wire elements that are coupled together. The device further includes a plurality of connector struts attached at a proximal end of the anchor stent, the connector struts coalescing to form a strut tip. A guide device, such as a guidewire, is attached to the anchor stent at the strut tip and may be used to guide the anchor stent into the arteries or other vessels and toward a target treatment site.

20. A wire anchor for an anatomical lumen, comprising:
-
a wire; an anchor including; a first expandable segment comprising, when expanded, a first diameter; a second expandable segment comprising, when expanded, a second diameter, wherein the second diameter is different than the first diameter; and a transition segment that, when the first expandable segment and the second expandable segment are expanded, ramps between the first diameter and the second diameter; and connector means to attach the second expandable segment to the wire.
