Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Comprehensive Assessment of Drug-Coated Stents Packaging Barrier Properties Drug-coated stents (DCS) have transformed the treatment of coronary artery disease, significantly reducing the risk of re-narrowing after angioplasty. The effectiveness of these life-saving devices depends not only on their intricate design and controlled drug delivery, but also critically on the integrity of their packaging. Given the inherent sensitivity of the drug coating, drug-coated stents packaging is of paramount importance. It must provide a robust shield against environmental factors, notably moisture and oxygen, which can degrade the drug and compromise its therapeutic efficacy, and maintain sterility as drug-coated stents are implanted medical devices susceptible to contamination. DCS packaging employs a combination of specialized materials designed to ensure both protection and sterility. Foil pouches, renowned for their exceptional barrier properties, are frequently utilized to effectively prevent moisture and oxygen ingress. Thermoformed trays are employed to securely hold and protect the delicate stent from physical damage during storage and transport. Medical-grade polymers are used for internal trays and protective layers, adding an extra layer of safeguarding for the sensitive device.

The packaging must exhibit exceptional barrier properties, effectively preventing moisture and oxygen from permeating and degrading the drug coating. The packaging must provide robust physical protection, safeguarding the delicate stent from damage during storage and transport. To validate these requirements, rigorous testing is conducted, focusing on: • Moisture Vapor Transmission Rate (MVTR): This test quantifies the rate...
