What is this "rod implant" material EVA ?

"subcutaneously implanted device comprised of buprenorphine and ethylene vinyl acetate co-polymer (EVA), a biocompatible copolymer that releases buprenorphine continuously for extended periods"


EVA AKA Ethylene Vinyl Acetate

EVA is the least expensive tennis shoe midsole material & is commonly found in entry level tennis shoes (Think Nike Benassi Swoosh Slides, those are EVA). The reason it's so inexpensive to make is because the Midsole is cut & shaped directly from flat sheets of EVA Foam. So while the PRO for Nike would be it doesn't cost them must to make, the CON would be EVA compresses & becomes flat over time due to the air trapped within the foam being squeezed out. Once the EVA Foam is compressed, it will never return to its original shape & it will no longer provide cushioning unfortunately. To add to the downside EVA Foam compresses faster then ANY OTHER Midsole Material.

This should give you an idea of what EVA material is.
