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.
