Patent No. EP3178501 (titled "Eluting Medical Devices") was filed by W L Gore & Associates on Mar 2, 2012. The application was issued on May 1, 2019.
A balloon catheter for localized drug delivery that prevents premature release of therapeutic agents during tracking and placement. The catheter features an expandable member coated with a therapeutic agent, a structural layer, and an outer sheath with a variably permeable microstructure. The sheath prevents drug elution in the unexpanded state, but transforms to allow rapid transfer of the hydrated coating and therapeutic agent upon expansion. This controlled release mechanism enables consistent "on-demand" delivery of therapeutic agents to the target site while minimizing systemic exposure.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
