Ray Ledinsky, Teleflex Medical OEM, provides expertise on designing a catheter to achieve optimal performance.

In catheter design, the functional requirements of the application allow the designer to identify performance requirements such as flexibility, lubricity, kink resistance, column or push strength, and torque transfer characteristics. Development of an optimal catheter design requires a strong understanding of catheter technologies to achieve the desired performance characteristics. This article offers a layer-by-layer approach to several design considerations for your device. At its simplest form, a reinforced catheter design is composed of an inner liner layer, a central reinforcement layer, and an outer polymeric overlayer.

Inner layer: Liners

When selecting a liner material, it is essential to consider ...
