Have studies been carried out on treatment with endobronchial Coils?

The material is called nitinol. It has already been extensively tested for long-term use inside the body and is used and well-tolerated in respiratory medicine, interventional radiology and angioplasty (e.g., stents.) Nitinol is an alloy of nickel and titanium.1  Coils should not be used in patients with hypersensitivity or allergy to nitinol or its constituent metals.

Since 2008, Coils have been the subject of clinical trials. They are commercially available since 2010.

More than 7.000 Coil treatments have been performed.


This treatment has been the subject of many investigations and clinical studies and showed safety and improvements to quality of life, lung function, and exercise capacity.2-7

The minimally-invasive procedure is performed bilaterally (on both the left and right lungs) and takes approximately 35 to 45 minutes per treatment. The second lung should be treated 1 – 3 months after the first procedure.

Coils are intended as permanent implants. While it is possible to remove single Coils, they should be removed only if medically indicated.

An MRI scan can be performed after Coil treatment provided that specific settings are used. Your Patient Implant Card provides further information on this.

Please share these details with your doctor before having an MRI scan.
