Abstract
A generally tubular braided flow diverting stent is formed of alternating round and rectangular elongated members, for treatment of aneurysms. The generally tubular braided flow diverting stent maintains a significant wall thickness while increasing area coverage of a vessel wall. Sliding of the round elongated members over the rectangular elongated members allows the stent to be crimped to very low diameters for delivery in narrow portions of the vasculature.
Claims23
A generally tubular braided flow diverting stent for treatment of aneurysms, comprising:
- at least one first elongate member helically wound in a first helical direction in a generally tubular shape, said at least one first elongate member having a substantially round cross-sectional shape;
- and
- at least one second elongate member helically wound in a second helical direction counter to said first helical direction and braided with said at least one first elongate member in said generally tubular shape, said at least one second elongate member having a substantially flat radially outer surface.
A generally tubular braided flow diverting stent for treatment of aneurysms, comprising:
- a plurality of first elongate members helically wound in a first helical direction in a generally tubular shape, said plurality of first elongate members having a substantially round cross-sectional shape;
- a plurality of second elongate members helically wound in said first helical direction in said generally tubular shape alternatingly between said plurality of first elongate members, respectively, said plurality of second elongate members having a substantially flat radially outer surface;
- a plurality of third elongate members helically wound in a second helical direction counter to said first helical direction and braided with said plurality of first elongate members and said plurality of second elongate members in said generally tubular shape, said plurality of third elongate members having a substantially round cross-sectional shape;
- and
- a plurality of fourth elongate members helically wound in a second helical direction counter to said first helical direction and braided with said plurality of first elongate members and said plurality of second elongate members in said generally tubular shape alternatingly between said plurality of third elongate members, said plurality of fourth elongate members having a substantially flat radially outer surface.
