Stent Manufacturing

Stent Manufacturing

A stent is a mesh tube that is used to keep an artery open, or to provide support to tubular structures. Stents are widely used in the medical sector as they are used in cardiovascular treatments and during renal procedures. Stent manufacturing is a very complex technique that needs to be undertaken with the highest levels of precision. The material used in manufacturing stents is just as important as the manufacturing process itself.

Certain materials such as Nitinol, platinum and titanium alloys, stainless steel and gold are used in the manufacture of stents because they can be machined without introducing heat affected zones. These materials are medically-approved and thus are widely used by manufacturers of medical-use stents.

With the advancement of medical science, new solutions and treatments are increasingly being devised. While most of us associate stents with cardiovascular procedures, there are several other medical applications where stents play an indispensable role. They are increasingly used in birth control, kidney stone pain control, gastro intestinal uses, esophageal uses, and others.

If these stents are to prove efficient in their applications, they need to be manufactured using the highest degree of precision and the use of the most advanced techniques. Of course, it all begins with precise design. Keeping of all these aspects in view, it is imperative that you partner with a manufacturer that can use their expert capabilities to bring you the best, most cost-effective solutions.

With the use of the right techniques, the minimum achievable feature size of a stent could be as low as 0.05mmThe type of machinery and equipment used in the manufacture of stents carries considerable significance. Production equipment used by leading manufacturers often comprises lasers, optics, CNC programs, positioning systems and so on.

There are certain codes that need to be adhered to. These would include certifications such as ISO 13485:2003 for medical manufacturing. A flexible, adaptable manufacturer will be able to meet the ever-evolving requirements of OEMs and hence it is important to partner with a firm that has a long-standing reputation.

Here are a few aspects to consider before you choose a stent manufacturing firm:

  • The firm should have a streamlined process of using the latest manufacturing, cutting, finishing and inspection techniques.
  • The firm’s established proficiency in processes such as nitinol shape setting is another crucial aspect that you shouldn’t fail to check.
  • If your firm of choice has experience in dealing with projects as varied as orthopedic implants, surgical device manufacturing, stent manufacturing and more, this experience would be an asset.
