Clinical Trial Summary

The Carbostent™ Radix 2 stent is a CE marked balloon expandable bare metal stent for the treatment of renal artery stenosis.

The aim of this post-market retrospective study protocol P12204, is to collect clinical data on patients treated with the RADIX 2 stent in routine clinical practice.

In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with the Radix 2 stent at least 12 months prior to the study start.

Description:

The objective of this post-market study is collect retrospective clinical data on the implantable medical device Radix 2 stent in an unselected population treated in the current clinical practice. Data will be collected via medical chart review in anonymous form.

Radix2 is a bare metal balloon expandable stent with a progressive multicellular design for treatment of renal artery stenosis. The stent is stent coated with i-Carbofilm™ to accelerate the rate of endothelization and strut coverage.

The product is CE marked and commercially available since July 2010. Additional technical information on RADIX2 is available online: http://www.alvimedica.com/Product/15/bms-b-e-radix2
