Safety and efficacy of biodegradable polymer-coated biolimus-eluting stents

The Egyptian Heart Journal, 2013
Background: Using drug eluting stents with a biodegradable polymer ensures that both the drug and coating are absorbed from the stent surface after completing their functions, which may reduce the need for prolonged antiplatelet therapy and decrease the ...

An investigation into the influence of stent strut thickness on in-stent restenosis using the finite element method [PDF]

, 2005
In-stent restenosis represents the major limitation for stenting procedures. In-stent restenosis is the renarrowing o f the artery lumen within a stent predominantly due to excessive growth of neointimal hyperplasia.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

In Stent Restenosis After Drug-Eluting Stent Implantation in a Patient with Polycythemia Vera: A Case Report

Journal of Agromedicine and Medical Sciences (AMS), 2023
Polycythemia vera happened in people around 40-60 years old and mostly men. The criteria are total red blood cells ≥36 mL/kg in males, thrombocytosis, leukocytosis, and JAK2 mutation.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Rhombic-Shaped Channel Stent with Enhanced Drug Capacity and Fatigue Life

Micromachines, 2017
A drug-eluting stent with rhombic-shaped drug reservoirs is proposed, aimed at providing long-term drug delivery and enhanced fatigue life. Unique rhombic-shaped reservoirs or channels on the stent struts can increase the total drug capacity and improve ...

Drug Eluting Stents en Belgique

, 2007
A côté des« stents » métalliques classiques, il y a, depuis quelques années, aussi des stents spéciaux avec médicament incorporé, pour traiter le rétrécissement des artères coronaires : les « drug eluting stents ». Le médicament est supposé empêcher une nouvelle constriction de l’artère. Quelle est l’efficacité de cette nouvelle technique ? A-t-elle un

The Best Strategy for the Black Hole Phenomenon between Intravascular Ultrasound and Optical Coherence Tomography

Diagnostics
The black hole (BH) phenomenon is an intraluminal restenotic lesion. It was identified by intravascular ultrasound (IVUS) and optical coherence tomography (OCT) after intracoronary brachytherapy and drug-eluting stent implantation. Despite the similarity
