Is a Drug-Eluting Stent the Default Treatment Strategy for Drug-Eluting Stent Restenosis?∗

open access: yesJournal of the American College of Cardiology, 2015
In 2001, when Morice et al. [(1)][1] presented the initial results of RAVEL (The Randomized Study With the Sirolimus-Coated Bx Velocity Balloon-Expandable Stent in the Treatment of Patients With De Novo Native Coronary Artery Lesions), showing 0% angiographic restenosis 6 months after ...

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

open access: yesAdvanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...

Everolimus‐Coated Laser‐Cut Self‐Expandable Metallic Stent Suppresses Stent‐Induced Tissue Hyperplasia in a Rat Gastric Outlet

open access: yesAdvanced NanoBiomed Research, EarlyView.
Everolimus‐coated laser‐cut self‐expandable metallic stents suppress stent‐induced tissue hyperplasia in the gastric outlet by reducing inflammation, fibrosis, and smooth muscle proliferation. Herein, we demonstrate the mechanical stability, sustained drug release, and histological benefits in a rat gastric outlet model, suggesting potential for ...

Artificial intelligence‐assisted design, synthesis and analysis of smart biomaterials

open access: yesBMEMat, EarlyView.
Smart biomaterials are rapidly emerging as tools for tissue engineering, and artificial intelligence has played essential roles in biomaterial studies. By bridging the literature gap in AI‐based design, synthesis and analysis of smart biomaterials, the current review shares perspectives on how biomaterial scientists can practically incorporate AI for ...

Drug eluting coronary stents [PDF]

open access: yesBMJ, 2002
Percutaneous coronary revascularisation has revolutionised the treatment of ischaemic heart disease during the past two decades. Despite technical refinements, however, long term results after using standard techniques remain limited by the phenomenon of restenosis—a process whereby elastic recoil and neointimal hyperplasia occur at the site of ...

Intravascular Ultrasound Findings Associated With Hydrodynamic Contrast Recanalization (HDR) of Coronary Chronic Total Occlusions

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hydrodynamic contrast recanalization (HDR) is a novel technique to facilitate wire crossing during chronic total occlusion (CTO) percutaneous coronary interventions (PCI). The mechanisms underlying HDR have not been fully described.

The Drug-Eluting Stent Saga [PDF]

open access: yesCirculation, 2009
Drug-eluting stents (DES) represent a breakthrough technology owing to their potent reduction of restenosis, which is a nuisance in the quality of life of affected patients, a rare cause of myocardial infarction (MI), and the principal shortcoming of stents compared with coronary artery bypass surgery.
