How Drug-Eluting Balloons Work Inside Blood Vessels The function of a drug-eluting balloon relies on controlled drug delivery during a short inflation period. When the balloon is expanded, the medication is released onto the vessel wall, where it is absorbed by surrounding tissue. The drug helps inhibit abnormal cell growth that can cause restenosis. Because the drug is delivered locally, systemic exposure is minimal, reducing the likelihood of unwanted side effects.
