Problems solved by technology
When one tries to place multiple stents and place multiple stents in the segment where implantation of the stent is most needed, the cost is very expensive because of the installation and material required for each stent
The time it takes to do so also adds cost and risk to the operation

Embodiment approach
[0078] In these designs, for example in open and closed cell constructions, variations of plaque tacks 5 may have a mesh configuration and may be configured with one or more circumferential members formed from separate struts.
[0079] A. Plaque nails with metal mesh
[0080] An embodiment of a plaque tack 10 in the form of a metal mesh structure is as Figure 3A to Figure 3D shown. The plaque tack 10 is shown as having a closed cell structure with an annulus 10a formed of an interlaced mesh, and radially outwardly extending protrusions 10b. Plaque tacks 10 may be formed by laser cutting or etching a metal tube or made of thin metal wires looped and interlaced in a mesh, i.e. welded, brazed, looped and / or joined together to form as Figure 3C to Figure 3D The desired mesh shape is shown. The protrusion 10b may protrude from the endless belt 10a. The protrusion 10b may be on the outer surface of the staple and may be in contact with and / or embedded in the vessel wall.

Abstract
An endoluminal device can be configured for precise positioning during deployment within a vessel. 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.
