Abstract

An endovascular support device for treatment of chronic restenosis or other vascular narrowing is disclosed together with a method of manufacture and a method for delivering a plurality of such devices to an affected area of a vessel. In a preferred embodiment, the endovascular support device comprises a unitary wire-like structure configured to form a plurality of upper and lower peaks which may be compressed for delivery to an affected area of a coronary or peripheral vessel in a human, and then expanded to maintain a passageway through the vessel.

Claims

1-3. -3. (canceled)

4. An intraluminal support device, comprising:

A plurality of balloon expandable rings parallel and adjacently aligned, each ring comprising axial turns, wherein at least one of the axial turns facing a first direction and at least one of the axial turns facing a second direction are not connected to an adjacently aligned expandable ring and have an ellipsoidal cross-section.

5. The support device of claim 4 wherein each of the plurality of straight portions is disposed between a pair of axial turns.

6. The support device of claim 5 wherein the straight portions extend from a first axial turn to a second axial turn.

7. wherein the rings are made of a metal alloy.

8. wherein the rings are expanded from a first expandable radius to a second expanded radius.
