The FDA retroactively banned PFOA residue from PTFE coated stents and guidewires. So you would have had people with PFOA contamination during endivascular surgery prior to that.
PFOA-free PTFE guidewires suffer higher risk of delamination, i.e. flaking of the ptfe coating which becone an embulus in your bloodstream.
The FDA does an amazing job at keeping us safe but the more evidence we have about the effects of novel substances the more I am biased to applying a cautionary principle.
In my pipe fixtures at home I will stick to hemp to seal the threads. If in the future I happen to need a stent, then I'll worry about it when I cross that bridge. :)
- refurb 4y agoWhy do you assume that hemp is safe?
- DoingIsLearning 4y agoHemp is being used by Humans since the Neolithic, we have been eating, wearing, and building houses with it for more than 10 centuries. If it really was unsafe the data would have revealed it a long time ago. Synthesized fluoropolymers have been around for about 60 years with an overall poor track record for Health and Safety. If we apply a moderate cautionary principle towards novelty and also consider the minor life quality improvements that these 3M innovations bring (fluoropolymers only make things slightly less incovenient they are not ground breaking in my life), then it really is a no brainer decision.
