AbstractThe most dreaded complication with percutaneous coronary intervention with stents, either bare-metal or drug-eluting stents is stent thrombosis (ST) and it has a significant detrimental effect on the outcome for the patient. The initial attempts at intervention with bare-metal stents had much higher rates of ST compared with what is currently prevailing in the modern interventional world. Significant changes with respect to the stent technology, pharmacology, and most importantly our understanding of this phenomenon have decreased the risk of ST. There are many factors that can be perf

The coronary artery stent has been widely used in clinic. In-stent restenosis was mainly caused by the excessive proliferation of smooth muscle cell and the inflammation due to the metal ion released from stent scaffold of the drug-eluting stent. Thus, to reduce the in-stent restenosis and promote the vascular endothelialization have become a hot research point in this area. In this paper, a nano-TiO2 ceramic coating was deposited on 316L stainless steel to reduce the metal ion release and to inhibit the inflammation reaction.

Self-expanding removable stents are used for the treatment of esophageal strictures. Partially covered metal stents become embedded in the esophageal wall due to mucosal tissue reaction providing good anchorage. This can also lead to extreme difficulty in the removal of such stents. Several different individual techniques have been used in literature for removal of these esophageal stents. Ours is the first case using a combination of cryoablation and stent-in-stent technique for removal of an extremely difficult case of embedded esophageal stent.

Although vascular stents have been widely used in clinical practice, there is still a risk of in-stent restenosis after their implantation. Combining conventional vascular stents with liquid metal-based electrodes with impedance detection, irreversible electroporation, and blood pressure detection provides a new direction to completely solve the restenosis problem. Compared with conventional rigid electrodes, liquid metal-based electrodes combine high conductivity and stretchability, and are more compliant with the implantation process of vascular stents and remain in the vasculature for a lon

However, TIPS occlusion remains a recognized complication, especially when bare-metal stents are used or when the cephalad end of the stent does not extend into the inferior vena cava (IVC). Antegrade recanalization of the occluded TIPS can be routinely achieved using a coaxial or a triaxial sheath system, which provides sufficient stability and pushability to recanalize the TIPS. However, occasionally this cannot be achieved due to the difficult angulatio

A bioresorbable stent supports the stenosed blood vessel during the healing period after coronary angioplasty and then gradually disappears. Unlike permanent stents, the biodegradable stent forms no obstacle for future interventions. Moreover, the degradable stent material presents an ideal vehicle for local drug delivery. Long term side effects inherent to drug eluting stents such as in-stent restenosis and late stent thrombosis might be avoided [1]. To date, several bioresorbable stents are being developed or are currently being tested in clinical trials. Two classes of biomaterials are bein

Stents are a medical device used to restore blood flow in stenosed vessels. During the process of stent expansion, the balloon and stent could damage the endothelial lining of the vascular wall and alter the mechanical stress states of various tissue components. The evolution of stents has progressed from bare metal stents to drug eluting stents or stents coated with drugs such as Sirolimus. Drug eluting stents are currently used to address the restenosis event that occurs after implantation. These stents have been effective but late stent thrombosis has been an emerging issue with drug elutin

Recent advances in angioplasty have involved the application of polymer coatings to stent surfaces for purposes of drug delivery in order to prevent a reblockage of the artery due to smooth muscle cell proliferation. This advance has reduced instances of such restenosis from ∼40% for bare metal stents to ∼5% for drug eluting stents, and has yielded a milti-billion dollar per annum market. However, delamination of polymer coatings on commercial stents has recently been reported using SEM analysis [1, 2]. Such delamination results from interface failure due to high interface tractions developed

Despite advances in endovascular stent design, stent structural integrity and in-stent restenosis remains a significant clinical problem worldwide. The role of stent corrosion and metallic ion release has not been thoroughly studied and little attention has been given to the interaction of stent materials with the surrounding vessel wall and the mechanical forces involved after implantation. Our recent studies on Stainless Steel (SS), Cobalt-Chromium (CoCr) and Nickel-Titanium (NiTi) stents obtained from a tissue retrieval resource from cadavers with accompanying clinical histories, have revea

Abstract Metal stents are placed in coronary arteries as an adjunct to balloon angioplasty with increasing frequency. The long term follow up to these clinical stenting procedures in currently three years. There is no published experience for longer periods and many concerns have been raised, including metal fatigue, stress-enhanced corrosion and stress-enhanced damage to adjacent healthy tissue. As a potential improvement to current metal stent designs, we are developing more compliant polymeric stents, employing bioresorbable materials.

Review question / Objective: This meta-analysis aimed to compare the clinical effectiveness and safety between radioactive versus normal stent insertion for patients with malignant hilar obstruction. Condition being studied: Malignant hilar obstruction (MHO) is a common clinical condition that is caused by the hilar cholangiocarcinoma, gallbladder carcinoma, or hilar metastasis. Most of the patients with MHO underwent palliative biliary drainage or stening by an endoscopic or percutaneous approach until end of life. The previous studies suggested that that bilateral stent placement and the use
