An embolization device for treating ischemic stroke is disclosed, having a surface, wherein the body portion is configured to have a radiopaque and electropositive surface under physiological conditions when the device is emplaced, which ionically binds a blood component in an amount effective to promote stability of device in situ to bind to a tissue component in an amount effective to increase adhesion of the device as compared to a device without an electropositive surface. Embolic coils being so delivered are electrolytically detachable in under 10 seconds, according to the disclosed vascular implant systems.
