Marker Bands & Ring Electrodes

Platinum-Iridium Marker BandsPI Medical manufactures radiopaque marker bands and ring electrodes to the industry’s tightest machining tolerances. We keep inventory of common sizes and common materials (platinum, platinum-iridium, gold, nitinol, and palladium) on the shelf for same day shipping. In addition to our standard, in-stock offerings, we welcome custom specifications for tolerances that can be several magnitudes greater, including exceptionally thin wall marker bands and ring electrodes.

Customized solutions include engineered features such as cut-outs or “windows” on the bands. We can also assist you in small-quantity prototyping projects.


Dimension Dimension Values
Smallest ID 0.0045" (0.1143mm)
Largest OD 0.5" (12.7mm)
OD/ID Tolerances +/- 0.0002" (0.00508mm)
Wall Tolerances varies based on ring size - as tight as 0.001" (0.0254mm)
Length Tolerances varies based on ring size; contact P&I

Note: A typical project will have two critical dimensions and one nominal (“reference”) dimension.

For Example: Critical OD x ID (Wall is the reference dimension), Critical OD x Wall (ID is the reference dimension), Critical ID x Wall (OD is the reference dimension)
