Abstract
The present disclosure describes methods and apparatus for endoluminal devices, such as stents, that have components with varying cross-sections at various points about the length of the endoluminal device, with various benefits resulting therefrom.
Claims32
A method of forming a stent comprising:
- supplying a wire having a generally elliptical cross-section;
- changing a first portion of the wire to form a non-elliptical cross-section;
- and
- forming the wire into a generally tubular shaped stent by forming the wire into one or more coils including an undulating pattern with a series of apical areas interconnected by generally straight sections,
- wherein the generally tubular shaped stent comprises at least one annular portion, wherein, within the annular portion, the non-elliptical cross-section is located in the series of apical areas of the undulating pattern,
- wherein each apical area of the series of apical areas is not abutting end to end any other apical areas of the series of apical areas of adjacent coils of the tubular shaped stent in a final implanted configuration,
- wherein the series of apical areas extend at least one circumferential turn of the one or more coils, and
- wherein, within the annular portion, each generally straight section of the wire located between the apical areas of the series of apical areas of the undulating pattern comprises the generally elliptical cross-section.

A method of forming a stent comprising:
- supplying a wire having a generally elliptical cross-section;
- changing a first portion of the wire to form a pattern on the wire, the pattern including non-elliptical cross-sections separated by the generally elliptical cross-section;
- and
- forming the wire into a generally tubular shaped stent by forming the wire into one or more coils including an undulating pattern comprising a series of apical areas interconnected by generally straight sections, each apical area of the series of apical areas including one of the non-elliptical cross-sections, and each apical area of the series of apical areas being separated from adjacent apical areas of the series of apical areas by the generally elliptical cross-section,
- wherein each apical area of the series of apical areas is not abutting end to end any other apical areas of the series of apical areas of adjacent coils of the tubular shaped stent in a final implanted configuration, and
- wherein the series of apical areas extend at least one circumferential turn of the one or more coils.
