    Abstract: The present disclosure relates generally to devices, systems, and methods for coil embolization, and, more particularly, to use and methods of forming coated coils. In an aspect, an embolic system may include a coil having a proximal end, a distal end, and a length therebetween slidingly disposed within a sheath. A coating may be disposed about the coil. A delivery filament may be configured to be slidingly disposed within the sheath proximal of the coil such that the coil can be ejected from the distal end of the sheath into the working lumen of a microcatheter. The coating may be configured to substantially fracture as the coil transitions from being substantially aligned with a longitudinal axis of the microcatheter to substantially misaligned with the longitudinal axis of the microcatheter upon being ejected from the microcatheter. The coating may be configured to plasticize after being ejected into an aqueous environment.

    Abstract: A medical device having a polymer-free outer surface layer comprising a crystalline drug selected from the group consisting of everolimus, tacrolimus, sirolimus, zotarolimus, biolimus, and rapamycin. The device may be produced by a method comprising the steps of providing a medical device; applying a solution of the drug to said portion of the outer surface to form a coating of amorphous drug; and vapor annealing the drug with a solvent vapor to form crystalline drug; wherein a seed layer of a crystalline form of said drug having a maximum particle size of about 10 μm or less is applied to at least said portion of the outer surface of the device before or after applying the drug solution, but before vapor annealing the amorphous coating.

    Abstract: A system and method for treating atherosclerotic plaque. The system includes a first catheter including an expandable balloon and a second catheter including a lumen in fluid communication with a distal hole. The method includes inserting the first catheter into a body lumen adjacent to a plaque formation, and deploying a balloon from the first catheter adjacent to the plaque formation. In addition, the method includes inserting the second catheter adjacent to the first catheter, and routing the distal end portion of second catheter along at least a portion of the deployed balloon of the first catheter. Further, the method includes routing at least a portion of the second catheter into a subintimal space adjacent to the atherosclerotic plaque. Furthermore, the method includes injecting a therapeutic agent into the subintimal space adjacent to the atherosclerotic plaque.
