If a company make any advertisement or any claim via any resources that company becomes liable to that claim in other words if company claims that’s there prosthetic limb can be used for extreme sports they have to do test and trials to successfully show that implementation. FDA regulation makes company abide to any claim they make but in terms of Lifespan if they don’t tell life span of the limb while using it for extreme sport it is going to fine until and unless they don’t make any specific claim like Even when you use this limb for adventure sports its life span is still so many years until and unless that is proved. If company makes a claim that this can be used for adventure sports and the life span of product is so many years it doesn’t mean that company just said that it can be used with adventure sports for so many years. The above claim made can be advertise as separate claims in same advertisement unitl both claims are true. Now it becomes doctors responsibility to complete understand the application and give patients the correct advise of what their opinion on the device and make sure any open ended statement are addressed before making any recommandation.
