The invention is directed to eluting medical devices that enable consistent 'on-demand' delivery of therapeutic agents to a vessel. The medical device of the current invention comprises an expandable member, a hydrophilic coating comprising at least one therapeutic agent about the expandable member or structural layer and an outer sheath with a variably permeable microstructure. The design and methods disclosed herein ensures that therapeutic agent delivery occurs essentially only during expansion of the expandable member, minimizing coating and/or therapeutic agent loss to the bloodstream and providing controlled delivery to the treatment site.

Eluting medical devices

This invention relates to the field of balloon catheters and more particularly to catheter balloons having controlled failure mechanisms for the prevention of catastrophic failure of the balloon during overpressure conditions.
