1. What is ePTFE and why is it important in medical devices? Expanded Polytetrafluoroethylene (ePTFE) is a biocompatible fluoropolymer with a microporous structure. It offers excellent chemical resistance, flexibility, and controlled porosity, making it ideal for vascular and neurovascular implants. Its ability to minimize thrombogenicity and allow tissue ingrowth while maintaining structural integrity is why it’s widely used in stent-grafts, heart valves, and endovascular co

In the world of advanced medical device engineering, membrane technology plays a crucial role in enabling precision, flexibility, and performance that meet the most demanding clinical and design requirements. 1. Design Freedom    Membrane technology offers complete design flexibility, enabling any size, shape, or style. This freedom allows engineers to tailor the membrane precisely to the device’s functional and anatomical requirements. 2. Control Functions    Using the Micr

In the rapidly evolving world of medical implants, every detail matters from adhesion strength to manufacturing efficiency. That’s exactly where advanced scaffold‑covering technologies make a meaningful difference. (1)  It begins with strong adhesion surface activation, which enhances chemical bonding by applying functional groups and verifying adhesion in every production lot, ensuring consistent and reliable performance. (2)  Selective sealing capability adds another laye

In catheter shaft design, manufacturing methodology directly defines device performance. Traditional telescopic reflow processes have long been used to assemble multi-layer shafts, but they introduce limitations in bonding quality, design flexibility, tolerances, and transition control. Microlayer technology fundamentally changes this paradigm by enabling a continuous, deposition-based approach that integrates structure, flexibility, and precision into a single process. Proc

In today's world of advanced medical technologies, precision is paramount, especially in the development of minimally invasive medical devices. The demand for microlayer tubes made from low durometer materials is on the rise, and they are quickly becoming a game-changer in the field. While extruded tubes have long been favored for applications requiring stiffness and high wall thickness, they present significant challenges when it comes to miniature sizes with ultra-thin wall

Microlayer technology represents a significant advancement in the design and manufacturing of medical tubing and catheter components. By enabling ultra-thin, highly controlled coating layers, Microlayer solutions provide unmatched precision, flexibility, and design freedom addressing many of the limitations found in conventional extrusion practices. Smooth, Controlled Transitions One of the key advantages of Microlayer technology is its ability to create seamless, gradual tra

Catheter tip performance plays a critical role in the overall functionality, safety, and clinical success of minimally invasive medical devices. Advances in material science and surface engineering now allow catheter tips to deliver higher performance while maintaining compact profiles and exceptional flexibility. Medibrane’s technology  enables a new generation of catheter tip designs by combining innovative coatings, controlled bonding methods, and enhanced mechanical prope

The important mechanical properties of vascular grafts include: 1. Compliance: This refers to the ability of the graft to expand and contract in response to pulsatile blood flow, mimicking the behavior of natural blood vessels. Compliance mismatch between the graft and native vessel can lead to complications. 2. Tensile Strength: This measures the graft's ability to withstand longitudinal and circumferential stresses without failure. Both longitudinal tensile strength (LTS) a

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

In the field of medical advancements, one material has proven to be exceptionally versatile and effective: Expanded Polytetrafluoroethylene (ePTFE). This extraordinary material is transforming how we address various medical challenges, particularly in cardiovascular treatments and beyond. Scaffold Encapsulation : The adjustable porous nature of ePTFE creates an ideal environment for tissue engineering, promoting cell growth and nutrient exchange when desired, or engineered to

Strong adhesion between coatings and substrates is essential for the safety and performance of medical devices such as expandable sheaths, catheters, and flow diverters. The image above, captured using scanning electron microscopy (SEM), demonstrates typical adhesion failures including delamination, edge lifting, and surface fragmentation—especially in high-stress regions.
