End-to-End Excellence in Cardiac Device Manufacturing
From electrophysiology catheters to structural heart implants, we accelerate your path to market with precision engineering and integrated manufacturing.
Engineering Innovative Cardiology Therapies

Cirtec partners with OEM customers to design, develop, and manufacture advanced cardiology devices across electrophysiology, structural heart interventions, cardiac rhythm management, and ventricular assist devices. Our expertise includes mapping and ablation catheters, transcatheter valve delivery systems, pacemakers, and ICDs. With in-house capabilities spanning multi-lumen extrusion, metal machining, sensor integration, and ASIC development, we deliver high-performance solutions that accelerate time-to-market for our partners.
Mastering the Details that Make Cardiac Therapies More Reliable
Key Capabilities
Electrode Rings

Engineered for today’s high-performance mapping and ablation catheters, our electrode rings combine ultra-low impedance pathways with micron-level dimensional control. Precision laser micromachining produces uniform band widths down to 0.2 mm, while automated vision inspection holds concentricity and gap tolerances within ±10 µm—critical for crisp electro-anatomical signal acquisition.
Proprietary surface finishing and precious-metal plating lower polarization, delivering stable pacing thresholds and repeatable RF energy delivery across thousands of duty cycles. From single-pole diagnostic rings to multi-ring assemblies pre-mounted on steerable shafts, Cirtec provides scalable manufacturing that shortens development time and elevates therapy accuracy for cardiac rhythm management devices.
Advanced Catheter Technologies

Engineered for demanding structural-heart and EP procedures, our catheters pair ultra-thin Pebax® or Grilamid® shafts with nitinol or stainless-steel braids to deliver 1:1 torque response and kink resistance through 270-degree bends. Laser-cut hypotubes, steerable pull-wire assemblies, and integrated sensor wiring are co-processed in a single pass, enabling distal OD ranges from 3 F to 22 F while preserving wall thicknesses of just 0.001 in.
Optional hydrophilic coatings, distal radiopaque markers, and balloon or coil-bonded tips arrive pre-assembled—shortening build time and accelerating first-in-human milestones.
Complex Extrusions

Our micro-precision extrusion lines produce multi-durometer, tri-layer, and bump tubes with up to 24 discrete lumens as small as 0.002 in—all held concentric within ±0.0005 in TIR. Reinforcement options include spiral-wound nitinol wire, PEEK or aramid fibers, and tungsten stripes for fluoroscopic visibility, giving designers a tunable mix of pushability, burst strength, and radiopacity.
In-line laser perforation and skiving embed side ports or suture rings without secondary ops, and our quick-turn cell can ship functional prototypes in as little as two weeks, seamlessly scaling to ISO 13485-certified volume production.
Precision Metals

From micromachined stent struts to hermetically sealed implant housings, our precision-metal cell combines 5-axis CNC, femtosecond laser cutting, and wire EDM to hold ±5 µm positional tolerances on features as fine as 0.050 mm. We work across implant-grade stainless steels, Ti 6Al-4V ELI, MP35N, nitinol, and platinum-iridium alloys—controlling grain structure and surface roughness to < 0.2 µm Ra for optimal fatigue life and biocompatibility.
In-house electropolishing, vacuum annealing, and precious-metal plating eliminate hand-offs, accelerating prototype-to-production ramps while meeting the rigorous ASTM F and ISO 13485 standards that next-generation cardiovascular and neurovascular devices demand.
Precious Metal Tubing

Manufacturing high-quality Nitinol tubing with industry-leading surface finishes and concentricity tolerances as tight as 0.01mm for transcatheter heart valves and neurovascular stents. Our proprietary processes achieve outer surface roughness values as low as 0.1μm (Ra), delivering exceptional performance in demanding applications. We complement our Nitinol expertise with capabilities in L-605, MP35N, tantalum, and titanium, ensuring optimal material selection for each device's unique requirements.
