They are spelled 'stent', just like the ones used to keep arteries open, but physically different. Here's a link:

I had ethyol/amifostine for half of my XRT, but had to discontinue it because I developed an allergy to it. Had no problems with nausea and took no meds.
Discontinuing it made a difference in my treatment experience because I didn't have to come in early, take shot and wait for it to be effective before my blasting sessions.
Darned expensive, also!
