A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of barbs or anchoring points on its outer annular periphery. The annular band has a length in the axial direction of the blood vessel walls that is about equal to or less than its diameter as installed in the blood vessel. In a preferred embodiment, the tack device is formed as a compressible metallic mesh band having outer barbs on outer sides of the mesh structure. Another embodiment may have a plurality of compressible mesh bands may be formed spaced apart coaxially from each other and connected by longitudinally extending bridge members. A preferred method is to perform angioplasty with a drug eluting balloon as a first step, and if there is any dissection to the blood vessel caused by the balloon angioplasty, one or more tack devices may be installed to tack down the dissected area of the blood vessel surface, in order to avoid the need to install a stent and thereby maintain a ‘stent-free’ environment.

An intravascular device can comprise a carrier and an expansion apparatus. The device can be used for intravascular treatment of atherosclerotic plaque. The carrier can be reversibly expandable and collapsible within a vessel and can have ribbon strips extending between opposite ends in a longitudinal direction of the carrier. The ribbon strips can each be formed with a plurality of elongated protrusions thereon. The expansion apparatus can be used to actuate the ribbon strips each with the plurality elongated protrusions to pierce a luminal surface of the plaque with lines or patterns of microperforations which act as serrations for forming cleavage lines or planes in the plaque.

A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of focal elevating elements on its outer annular periphery for holding loose plaque under a spring or other expansion force against a blood vessel wall. The focal elevating elements are designed to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the intraluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

A plaque tack device for treating atherosclerotic occlusive disease is formed as a thin, annular band made of thin, flexible wire formed in a mesh structure having a plurality of barbs on its outer periphery. It has a width that is small relative to its diameter, to minimize the amount of foreign structure placed in the blood vessel. One or more tacks may be applied in positions along a plaque accumulation site as needed to stabilize the site and/or hold pieces of plaque out of the way of blood flow. The barbs of the tack may be pressed into the plaque and/or blood vessel walls by balloon expansion. Related methods of deployment and delivery devices are provided for insertion of the plaque tack in a compressed state into the blood vessel and expanding it back to its annular shape for holding plaque against the blood vessel walls.

An improved stent device has a body structure in tubular form sized to an organ lumen in which it is to be used and made of a wire mesh or cage structure of interwoven or interdigitated strut sections, and a plurality of focal elevating elements of relatively small point-like size or vector-like edge in an array over outer surfaces of the wire mesh or strut sections of the stent body structure. The focal elevating elements elevate the wire mesh or strut sections away from and minimize surface area contact with the organ lumen walls. They also reduce contact pressure in regions neighboring the focal elevating elements in order to minimize trauma due to contact or movement against the organ lumen walls. A preferred use for the stent device is in a blood vessel lumen, particularly to retain plaque dissection after balloon angioplasty.

A system for delivering a surgical staple can include various components. The system may include an elongate body with a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end. A sheath can move relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most distal delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least one delivery platform. A plurality of intravascular tacks can be within the system with each disposed about a corresponding delivery platform.

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.
