1. What is Dacron and why is it used for stent coverings? Dacron (polyester) is known for its strength, durability, and biocompatibility. It's commonly utilized in vascular grafts and stent coverings due to its excellent sealing properties and ability to promote tissue ingrowth. 2. What are the benefits of using Dacron fabric on stents? Offers high mechanical strength and resistance to tearing. Its porosity encourages tissue integration, minimizing migration risks. Demonstrat

When it comes to choosing materials for stents and other vascular devices, Dacron (Polyethylene terephthalate or PET) and ePTFE (expanded Polytetrafluoroethylene) each offer unique advantages and are suited to different applications. Here’s a quick comparison:   Dacron (PET) 🔹  Advantages: 1. Excellent mechanical strength 2. Porous structure for tissue ingrowth 3. Ideal for larger vessels (>10mm) 4. Easier to suture   🔹  Disadvantages: 1. Initial inflammation potential 2. T
