The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device. ## Claims ### Claim 1 A self-expanding endoluminal device configured for precise positioning during deployment within a vessel, the endoluminal device having a longitudinal axis extending between a distal end and a proximal end, the endoluminal device configured for radial compression and expansion comprising: a first undulating ring disposed at the distal end extending circumferentially around the longitudinal axis, the first undulating ring comprising a plurality of struts, a plurality of inward apexes and a plurality of outward apexes, wherein at least two struts connect at one of the apexes, the outward apexes being distal of the inward apexes; and a proximal portion connected to the inward apexes; wherein, the endoluminal device is configured for delivery such that the first undulating ring can at least partially expand while the proximal portion remains compressed, in this position: a first strut of the plurality of struts extends at an angle radially outward from the longitudinal axis, the first strut connected to the compressed proximal portion; a second strut and a third strut of the plurality of struts are connected to the first strut and extend parallel to the longitudinal axis, the second and third struts forming a foot and the endoluminal device comprising a plurality of such feet configured to extend parallel to the longitudinal axis when the endoluminal device is in this partially expanded position, the feet positioned circumferentially around the longitudinal axis and configured to precisely position and orientate the endoluminal device within the vessel upon further expansion and deployment of the endoluminal device within the vessel. ### Claim 2 (depends on 1) The endoluminal device of claim 1, wherein the proximal portion comprises a second undulating ring disposed at the proximal end extending circumferentially around the longitudinal axis. ### Claim 3 (depends on 2) The endoluminal device of claim 2, wherein the proximal portion further comprises a plurality of bridge members connecting the first undulating ring and the second undulating ring. ### Claim 4 (depends on 3) The endoluminal device of claim 3, wherein each of the bridge members comprises at least one anchor. ### Claim 5 (depends on 4) The endoluminal device of claim 4, wherein the at least one anchor is configured such that partial expansion of the endoluminal device to the partially expanded position causes the anchor to move out of plane from the rest of the compressed proximal portion. ### Claim 6 (depends on 1) The endoluminal device of claim 1, wherein the proximal portion comprises a plurality of anchors. ### Claim 7 (depends on 6) The endoluminal device of claim 6, wherein each of anchors of the plurality of anchors is configured such that partial expansion of the endoluminal device to the partially expanded position causes the anchor to move out of plane from the rest of the compressed proximal portion. ### Claim 8 (depends on 1) The endoluminal device of claim 1, wherein the second and third strut are connected at a first inward apex of the plurality of inward apexes. ### Claim 9 (depends on 8) The endoluminal device of claim 8, wherein the first inward apex is positioned distal of the connection between the first strut and the proximal portion. ### Claim 10 (depends on 9) The endoluminal device of claim 9, wherein the first strut is connected to the proximal portion at a second inward apex of the plurality of inward apexes, such that the second inward apex is spaced proximally from the first inward apex. ### Claim 11 (depends on 1) A system comprising the endoluminal device of claim 1, and a delivery device, wherein the delivery device comprises a sheath configured to surround the endoluminal device when the endoluminal device is in a compressed position within the delivery device. ### Claim 12 (depends on 1) The endoluminal device of claim 1, wherein the endoluminal device comprises a staple or a stent. ### Claim 13 An endoluminal device, comprising: a first circumferential member disposed at a distal end of the endoluminal device, the first circumferential member having a first outward apex disposed between first and second struts, a second outward apex disposed between third and fourth struts, a first inward apex disposed between the second and third struts, and a second inward apex disposed adjacent to the fourth strut; a second circumferential member disposed at the proximal end of the endoluminal device; and a bridge member having a first end coupled with the second inward apex and a second end coupled with the second circumferential member, the bridge member having a plaque anchor disposed at or adjacent a central zone of the bridge member; wherein the first inward apex extends a first axial distance from a central zone of the bridge member and the second inward apex extends a second axial distance from the central zone of the bridge member, the first distance being greater than the second distance, such that the second and third struts form a foot that can extend outward from the second circumferential member when the endoluminal device is in a partially expanded position, the foot being substantially parallel to a longitudinal axis of the endoluminal device. ### Claim 14 An endoluminal device, comprising: a first circumferential member disposed at a distal end of the endoluminal device, the first circumferential member having a first outward apex disposed between first and second struts, a second outward apex disposed between third and fourth struts, a first inward apex disposed between the second and third struts, and a second inward apex disposed adjacent to the fourth strut; and a second circumferential member disposed at the proximal end of the endoluminal device; wherein the first inward apex is positioned distally from the second inward apex, such that the second and third struts form a foot that can extend outward from the second circumferential member when the endoluminal device is in a partially expanded position, the foot being substantially parallel to a longitudinal axis of the endoluminal device. ### Claim 15 (depends on 14) The endoluminal device of claim 14, wherein a first plurality of outward apices and a second plurality of outward apices are aligned along the longitudinal axis. ### Claim 16 (depends on 14) The endoluminal device of claim 14, wherein a first plurality of outward apices is spaced proximally from a second plurality of outward apices along the longitudinal axis. ### Claim 17 (depends on 14) The endoluminal device of claim 14, further comprising a bridge member extending between the first and second circumferential members. ### Claim 18 (depends on 17) The endoluminal device of claim 17, wherein the bridge member has a first end connected to the second inward apex and a second end coupled with the second circumferential member. ### Claim 19 (depends on 17) The endoluminal device of claim 17, further comprising at least one anchor located on the bridge member.
