  • APPLICATIONS

    Angiography (Diagnostic) – When visualization is of primary importance such as in angiography, our biocompatible catheter components are chemically unreactive not only with the body but also with dyes used for contrast material. Zeus components are able to withstand a range of sterilization protocols to minimize the risk of catheter-associated infections.

    Angioplasty – Balloon catheter procedures focused on widening narrow biological passages have a variety of roles in health care. Whether for angioplasty, drug delivery, or stent and scaffold deployment, Zeus catheter componentry is continuously being improved to meet the evolving technological needs for the treatment of atherosclerosis.

    Atherectomy (Ablation) – For specialized applications where the atherosclerosis plaque has become calcified, these unique catheter assemblies require optimized flexibility and control. Zeus catheter components provide insulation, added wall strength, lubricious guide wire manipulation, tight tolerances, and greater pushability.

    Delivery Catheters – These devices are similar to guiding catheters in construction but are designed to pass through them to deliver treatments. These catheters deliver such state-of-the-art treatments as artificial heart valves to catheter-sized pacemakers using Zeus ultra-thin PTFE liners. These liners are the thinnest in the industry allowing a larger lumen or a reduced profile. Together with our non-metallic braid options such as LCP, multi-durometer jacket materials, and customized heat shrinks, our catheter components allow you the freedom to design your optimum next generation solution.

    Guiding Catheters – Constructed for strength and flexibility while minimizing the space required, this catheter design allows for safe passage of other devices and materials through it. These catheters use our ultra-thin PTFE liner on the inside diameter (ID) for an exceptionally lubricious working channel. This braided catheter is typically coated with a multi durometer outer jacket reflowed with our FEP heat shrink or FluoroPEELZ® for easy navigation within the vasculature.

    Guide Wire Coverings – Available for a variety of purposes, these coverings can be tailored according to diameter, taper, and choice of fluoropolymer. These coverings provide high lubricity for smooth tracking in difficult anatomical spaces and at distal regions.

    Imaging – From angiograms to intravascular ultrasound (IVUS) to optical coherence tomography (OCT), Zeus catheter componentry improves the ability of imaging catheters to navigate tortuous anatomical spaces for proper image acquisition and characterization of plaque. Our drawn fiber and LCP monofilament products increase catheter stability and torque while enabling the capture of detailed geometries and electrical maps. Catheters made with our products enhance interventional planning, stent sizing, detection of stent strut malapposition, intimal dissection, neointimal growth, and in-stent thrombosis.

    Micro-Catheters – As technologies improve and implantable devices become smaller, physicians have the opportunity to deliver new solutions through minimally invasive devices that avoid costly surgery and lengthy recovery. While advancements have allowed these solutions to become smaller, the vasculature remains the same size. We have addressed these needs with our thinner, stronger, and more flexible extruded PTFE liners and catheter componentry to continue to deliver advanced lifesaving tools.

    PCI (Percutaneous Coronary Intervention) – Our products are conceived and created to support the critical demands of medical device industry. Whether a manufacturing aid or a permanent implant, Zeus manufacturers components with the thinnest walls, tightest tolerances and customized mechanical properties to provide your next life saving device the flexibility and strength for the most challenging anatomical locations.
