Catheter Electrode Rings
Automated, high-density electrode rings for precise cardiac mapping and ablation
The Conduction Hubs Behind Every Signal
Catheter electrode rings provide the low-impedance electrical interface that captures cardiac signals and routes ablation energy inside mapping and therapy catheters. By combining biocompatible, high-conductivity metals with tight-tolerance geometries, these rings deliver consistent contact, even on shafts only a few French in diameter. Precise ring spacing and surface finish directly impact signal fidelity, lesion quality, and overall procedural success, making electrode design a critical factor for next-generation electrophysiology and neurovascular systems.
Our Electrode Ring Capabilities
See how Cirtec’s vertically integrated metals, laser, and electronics teams shorten the path from electrode concept to volume-built, shaft-mounted rings.
Platinum-iridium, platinum, stainless steel, and Nitinol alloys deliver biocompatibility, corrosion resistance, and conductivity. We support ring diameters from 0.5 mm to 1 mm and custom lengths to match up to 64-electrode arrays for high-density mapping and ablation catheters.
5-axis CNC micromachining, micro-stamping, and laser cutting achieve ±0.0005 in tolerances on features as small as 0.004 in while maintaining mirror-finish surfaces that minimize noise and thrombus risk.
Reel-to-reel manufacturing, automated pick-and-place, and ultra-small laser welds ensure concentric placement and hermetic bonds between rings and leads—scaling smoothly from pilot to millions of units.
Rings are pre-configured for force, temperature, or impedance sensing and pair seamlessly with Cirtec ASICs that offer programmable currents, real-time impedance checks, and high-channel data capture for closed-loop control.
