HELICAL HYBRID STENT
First Claim
1. A stent comprising:
- a helical main stent component having a tubular structure extending from a first end to a second end, the helical main stent component having a first side band and a second side band, wherein the first and second side bands are coextensive and wherein each of the first side band and the second side band has an undulating pattern and forms a plurality of helical windings;
a polymer material interconnecting at least a plurality of the main stent component helical windings; and
a drug.

Abstract
An expandable helical stent is provided, wherein the stent may be formed of an amorphous metal alloy or other non-amorphous metal with a securement. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic particular to that stent. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other-maintain the tubular shape of the helically coiled stent and prevent the polymer layer from sagging at any point between cycles of the coils.

32. A method of delivering a stent to a target vessel, comprising:
-
introducing into a vessel said stent comprising a helical main stent component extending from a first end to a second end, the helical main stent component having a first side band and a second side band, wherein the first and second side bands are coextensive and wherein each of the first side band and the second side band has an undulating pattern and forms a plurality of helical windings, a polymer material interconnecting at least a plurality of the main stent component helical windings, and a drug; and delivering said stent to said target vessel. - View Dependent Claims (33, 34)
