When designing covered stents, we typically focus on the usual levers: base material, ePTFE microstructure, and wall thickness. One design parameter that often receives less attention—but can significantly influence vascular healing and neointimal hyperplasia—is how effectively the cover is mechanically coupled to the stent struts. In practical terms:Well‑adhered covers support more stable healing, while poorly adhered covers can promote chronic inflammation and excessive tis

1.     Why does the design of a stent cover layer matter for tissue growth? Because the cover layer is the primary biological interface between the device and the body. Its microstructure strongly influences how blood proteins, platelets, inflammatory cells, and tissue interact with the implant. Small changes in pore size, porosity, or surface chemistry can meaningfully affect healing, thrombosis risk, restenosis, and long‑term device performance. 2.     What is meant by “int

In many medical devices, the way two materials meet and stay bonded is just as important as the design of the device itself. When metals, polymers, textiles, and coatings connect, their interface determines how the device performs, how long it lasts, and how safe it is inside the body. Covered Stents and Scaffolds Covered stents must combine the strength of a metal scaffold with the flexibility of a thin covering. That covering has to stay attached while the device bends, exp

Bonding Microelectronics components  to Balloons, Stents, and Catheters Integrating electrodes, sensors, and PCB assemblies onto balloons, stents, and catheter shafts is a major engineering challenge. These components must remain securely attached while the device bends, expands, compresses, and moves through tortuous anatomy. Traditional bonding techniques struggle to meet these requirements.   The Problem with Conventional Methods Most manufacturers still rely on manual adh

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.
