Hi,
End-of-life (EOL) Medical devices have been included in the EU WEEE directive (Category 8); please go through the definition of "Producer" and "Distributor" which will give you an idea of your responsibility with respect to EOL product that you export to EU. You may like to download the EU WEEE directive for your reference (e.g.
http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:037:0024:0038:EN:PDF). Please note that the interpretation/application of the directive may vary from country to country. It is always better to check with your contacts in the country to which you would be exporting the product on the finer aspects of your responsibility to EOL products. You may also have to check for new notifications by EU on WEEE regularly to see if there is any additional responsibility because of the new notification.
By the way, unlike consumer electronics products, Medical Devices have a long life and generally go for reuse /re-manufacture / repair many times before finally disposed.
With kind regards,
Ramakrishnan
