Radiopaque Marker Bands: Metal Choice And Production Process

In the medical device industry, it is essential that the tool suit the need. When it comes to specific devices, exactitude is required in order for the tool to fulfill its role. This requires precision in the production methods of small and some miniscule components that comprise a medical device. This is certainly the case with the production of radiopaque marker bands on various devices.

What Are Radiopaque Markers?

Radiopaque is a term referring to the ability to be opaque (You cannot see through it as it is solid) to any form of radioactivity or radiation. The most common form of radiation is, of course, X-rays. The most common type of radiopaque object is of metal. As a result, if you run an X-ray machine over something containing metal, you can see the metal object or item.

Radiopaque markers consist of thin-walled, seamless, slender tubes of metal. The metal types may vary in accordance with the specifications of the task. They come in various diameters and adhere to the specifications of the clients. Fabricators place the bands equidistant and strategically along a medical device such as a catheter. This makes them clearly visible when placed under an x-ray fluoroscope.

Purpose of Radiopaque Markers

Radiopaque markers have one specific purpose. They clearly delineate – mark, the position of the device. As a result, the medical professional can track its position throughout the deployment process. Overall, the markers ensure the professionals can clearly view and follow the passage and presence of an implantable device such as a catheter even during a procedure that requires the use of either radiography or fluoroscopy.

Metals Used to Produce Radiopaque Marker Bands

Although plastic marker bands are currently in use, the more common types are made from one of several high-density and precious metal. Among the most common metals employed in this process are:

* Gold
* Palladium
* Platinum
* Tantalum

These are the standard metals employed radiopacity is required.

Process to Produce Radiopaque Markers

The process to produce radiopaque markers is not simple. It requires several steps to produce the desired result. The initial process produces several markers in the diameters specified by the client. The operator cuts them to the appropriate lengths. Next, the fabricator crimps or swages the bands to the shaft of the catheter or other medical device. This requires attention to detail. Every aspect demands the fabricator follows exacting quality assurance procedures. Only such stringent controls will make certain the bands adhere to the medial device.

The Radiopaque Marker Band

In the medical profession, preciseness is extremely important. Of further concern are the specific properties of the instruments and their components. When it comes to catheters, for example, it is extremely important to be sure those instruments that reach the high standards of quality. The addition of a radiopaque marker band to such devices requires strict attention and exactitude if the resulting product is to retain its ability to perform its tasks with safety and accuracy.
