The fibrous cap is a layer of fibrous connective tissue, which is thicker and less cellular than the normal intima, found in atherosclerotic plaques. The fibrous cap contains macrophages and smooth muscle cells. The fibrous cap of an atheroma is composed of bundles of muscle cells, macrophages, foam cells, lymphocytes, collagen and elastin.
Stent with anchors to prevent vulnerable plaque rupture during deployment
InactiveUS7258697B1Reducing fibrous cap stressPrevent high expansion forceStentsBlood vesselsVulnerable plaqueFibrous cap
A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent achieves staged expansion through stronger and weaker circumferential regions, and includes optional anchors positioned at the circumferential transition between the stronger and weaker regions. During the first stage expansion, the weaker region expands moving the anchors laterally apart. The anchors straddle the fibrous cap and embed into the vessel wall. The second stage expansion of the stent exerts gentler stresses by the weaker region against the fibrous cap while the stronger region exerts greater stresses on the remainder of the vessel wall to open the vessel.

Method of treating vulnerable plaque using a catheter-based radiation system
The invention provides a method of treating vulnerable plaque at a site in a vessel. A vulnerable plaque site is identified for treatment. A radiation source is introduced into a vessel containing a vulnerable plaque site identified for treatment. The radiation source is guided to a position adjacent to the treatment site. A therapeutically effective dose of radiation is delivered to the vulnerable plaque site. As the radiation impinges upon the wall of the lumen, it promotes cell growth. Such growth can serve to strengthen the thin fibrous cap found atop a vulnerable plaque lesion. With the lesion thus stabilized, time is provided for the use of statin drugs or other agents to shrink or remove the lipid pool beneath the cap.

A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent includes inclined planar rings joined by interconnecting links. The planar rings are inclined relative to a plane perpendicular to a longitudinal axis extending the length of the stent. The inclined planar rings provide vessel support yet require lower balloon pressures to deploy and exert lower radial stresses so that when appositioned with vulnerable plaque are less likely to rupture the fibrous cap.

An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for rupturing a fibrous cap to controllably release vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by links. The stent includes struts and links of varying strengths about the circumference of the stent. The weaker struts and links require less force to open and, hence, may apply more stress to rupture the fibrous cap while the stronger struts and links protect the healthy portions of the body lumen. In another embodiment, the stent may include stress concentrators positioned on outer surfaces of the links. The stress concentrators are aligned with the fibrous cap prior to stent expansion so that upon stent expansion, the stress concentrators induce stress to rupture the fibrous cap, thereby releasing the vulnerable plaque.

Method and system for atherosclerosis risk scoring
InactiveUS20070003116A1Ultrasonic/sonic/infrasonic diagnosticsImage enhancementNecrotic coreImaging modalities
A method for characterizing the risk associated with atherosclerosis is disclosed. The method uses one or more images of cross-sections of the artery or other vessel of interest to identify and locate components of the atherosclerotic deposit, including any hemorrhage, necrotic core, and calcification, and to determine the status and composition of the fibrous cap. In one embodiment, high resolution MRI images are utilized, although other imaging modalities may alternatively be used. A simple scoring system is applied that accounts for the presence of these components and more heavily weights the presence of these components in the juxtaluminal portion of the deposit. The status of the fibrous cap (intact or ruptured) and the composition of the fibrous cap (collagen or mixed tissue) are also incorporated into a final atherosclerosis risk score.

The invention provides a modeling method for new blood vessels in abdominal aorta atherosclerotic plaques of a New Zealand white rabbit, which comprises the following steps: at nearby positions whereplaques need injection in an abdominal aorta of the New Zealand white rabbit fed by balloon injury plus high cholesterol for 12 weeks, under ultrasonic guidance in the blood vessel, a pair of fine forceps are used for accurate positioning by pressing a vascular lumen at a vascular adventitia to cause local deformation and removing pressure to restore the shape of the lumen; FGF-2, VEGF-A or mixedlentiviruses of both are injected into the plaques; plaque-injected sites are located by both an iliopsoas suture and the distance of iliac arterial bifurcation; and the New Zealand white rabbit continues to be fed by high fat for 8 weeks. The modeling method can effectively construct plaques which are rich in new blood vessels, and a modeling success rate reaches 100 percent. A pathological section and H&E chemical staining prove that the rich new blood vessels can be seen in the plaques no matter which of VEGF-A, FGF-2 or a VEGF-A+FGF-2 mixture is injected, even the new blood vessels alreadygrowing into fibrous caps of the plaques (figure 6) can be seen, and in comparison with a normal saline-injected control group, the difference reaches statistical significance (P<0.05).
