Dual therapy stent
Dual Therapy Stent
A Dual Therapy Stent (pronunciation: du·al | \ ˈdü-əl \, ther·a·py | \ ˈther-ə-pē \, stent | \ ˈstent \) is a type of medical device used in the treatment of coronary artery disease (CAD).
Etymology
The term "Dual Therapy Stent" is derived from the device's dual functionality. It combines the mechanical function of a traditional stent with the drug delivery function of a drug-eluting stent.
Description
A Dual Therapy Stent is designed to prevent the artery from closing after an angioplasty procedure, while also delivering a drug to the site to prevent restenosis (re-narrowing of the artery). This dual functionality is achieved by coating the stent with a drug-polymer combination. The drug is gradually released over time, helping to prevent the formation of scar tissue that could lead to restenosis.
