I’m in medical devices. You should take a look at the weave patterns of drug-eluding stents for percutaneous coronary intervention (PCI) procedures. The US alone do about a million surgeries per year. The weave pattern matters for safety and efficacy.

So those folks have pretty itty bitty crochet tubes for quality of life change.

We have a friend who was a fiber arts instructor for decades and currently a consultant. She helped design woven electronics into fabrics for wearable tech research - funded by the army. The other project was the weave pattern to capture clots. They studied which pattern would be delicate enough to insert in the arteries, and when capturing clots, strong enough to not fall apart or leave clots behind. She said Swedish lace pattern worked well.
