Material Selection
​PTFE - PTFE is the most ubiquitous fluoropolymer for vascular catheters. It is most commonly used as a lubricious inner catheter liner because it has the lowest coefficient of friction of all catheter materials. Catheters using PTFE are usually hand-assembled because PTFE cannot be melt-processed by conventional extrusion methods.
PU- PU is one of the key polymers in the vascular catheter market. The diversity of urethanes used in catheters is significant. Polyurethanes varieties include polyester, polyether, and polycarbonate-based varieties, as well as aromatic and aliphatic grades. Polyamide (Nylon) - Polyamide such as Nylon 11 and Nylon 12 are materials of choice in applications such as percutaneous transluminal coronary angiography (PTCA) applications, including balloon and stent delivery devices, where greater stiffness is required and softening at body temperature is not desired.
Polyamide (Pebax) - Pebax are modified nylons with soft segments that provide more elasticity than polyamide 11 or 12. They have become materials of choice in many interventional catheters because they combine the flexibility and softness of polyurethanes with the strength of nylons.
Polycarbonate-based PU - Polycarbonated-based PU exhibit excellent long-term biostability and are commonly used in applications that are in the body for long periods. Aliphatic and aromatic polyether-based polyurethanes soften at body temperature, which promotes patient comfort and reduces the risk of vascular trauma. These are commonly used for in-dwelling catheters, such as a peripherally inserted central catheters (PICC) and central venous (CV) catheters.
HDPE - HDPE is commonly used as a liner for the inner lumen of vascular catheter designs and as a complete shaft because it can be melt-processed by extrusion. It does not have as low a coefficient of friction as PTFE but is superior to polyamides and polyurethanes. It is also harder than PTFE, which can result in a lower effective coefficient of friction compared with PTFE in some applications. Where devices or components are advancing down a working channel, PTFE has a tendency to plow up in front of the component, increasing the deployment force. Because HDPE is harder, it does not plow up, reducing the deployment force even though the coefficient of friction is higher.
PEEK - PEEK is considered one of the most rigid polymer with high tensile modulus and ultimate tensile strength. It is used in catheters where high strength or heat resistance is required, such as ablation devices. PEEK has similar mechanical properties to polyimide, but it is a true thermoplastic and can be extruded in a continuous process.
