A radiopaque marker band is a marker ring used as an X-ray or ultrasound imaging marker for the distal working area in interventional therapy, and it is disposable medical material.
The performance requirements for this purpose of the material itself are biocompatibility and radiopaque, high precision is also required. 
Common applications include radiopaque marking, ring electrodes, cardiac rhythm management devices, stents, and angioplasty. It is suitable for radiopaque markers during angioplasty and other minimally invasive catheter procedures. We have developed a proprietary manufacturing process that guarantees a high-precision and burr-free surface finish. We specialize in custom marker band that meets your exact specifications.
Edgetech is a global supplier of marker bands, ring electrodes and other cutting tubular components for a variety of applications. Our advanced manufacturing capabilities and vertically integrated solutions accelerate your time to market. While adhering to the highest quality standards, we offer precision tubing in a variety of materials, diameters, wall thicknesses, lengths, and edge finishes.
Radiopaque marker bands applications
Our precious metal and radiopaque marker bands are used in a variety of advanced medical devices and applications, including:
catheter
Conveyor system
Implants
angioplasty
fluorescent lighting
We do not have standard stock markers, we offer custom specifications with tolerances that can be orders of magnitude larger, including extremely thin wall marker band and ring electrodes. Custom solutions include design features such as cutouts or “windows” on the strap. We can also assist you with low-volume prototyping projects.

Production Process Description
(1) Raw Material: the raw materials are metal pipes;
(2) Raw material inspection: The chemical composition report is provided by the original factory, and it is verified according to the relevant standards required by the factory and if necessary, sent to a third party for inspection; the size and appearance are inspected and judged by our IQC according to the incoming inspection standard.
(3) Cleaning: The process of cleaning is to use an ultrasonic cleaning machine and special metal degreasing and decontamination cleaning agent, alcohol, and pure water; the finished product is cleaned with alcohol and pure water in the 100,000-level clean workshop.
(4)Heat treatment: It is designated as a special process, which is to recrystallize and anneal the hardening during the processing of the pipe. The purpose is to reduce the hardness of the pipe and restore the elongation, so that the pipe can be processed multiple times.
(5)Drawing: cold drawing, the outer diameter and wall thickness of the pipe are controlled by the mold at room temperature, and the auxiliary material is metal drawing lubricating oil.
(6)Cutting: The pipe is processed into a capillary with the required outer diameter, wall thickness, and inner diameter, and then cut to the required length by an automatic cutting machine or a laser cutting machine.
(7)Roll grinding: deburring treatment, and the auxiliary materials are corundum abrasive and pure water.
