1. An intravascular device comprising:
- a tubular element that is radially expandable from a compressed profile configuration to an expanded configuration, said tubular element comprising a wall, a proximal end, a distal end and a central portion therebetween;
the tubular element further comprising at least two shape set twisted elongate standards extending in a helical fashion along the wall from the proximal end to the distal end when the tubular element is in the expanded configuration; and
the tubular element further comprising;
(i) a first plurality of V-shaped bands, each band including at least one end connected to a first elongate standard and a second end connected to another elongate standard, wherein the first elongate standard, the other elongate standard, and the first plurality of bands together define a first helical spine, wherein axially adjacent V-shaped bands are separated by a gap and at least some of the axially adjacent V-shaped bands are connected by S-shaped connecting members; and
(ii) a second plurality of V-shaped bands, each band including at least one end connected to a second elongate standard and a second end connected to another elongate standard, wherein the second elongate standard, the other elongate standard, and the second plurality of bands together define a second helical spine, wherein axially adjacent V-shaped bands are separated by a gap and at least some of the axially adjacent V-shaped bands are connected by S-shaped connecting members.

Abstract
An aneurysm occlusion system includes a device positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes an expandable tubular element having a lumen surrounded by a sidewall including a plurality of gaps. When expanded, the tubular element includes longitudinal standards arrayed helically in a proximal to distal direction. The standards support struts and the gaps are defined between adjacent struts and are sufficiently large to permit delivery of embolic coils or other embolic materials therethrough.
