Abstract: Embodiments of the present disclosure are directed to systems, methods and device for providing embolic protection in a patient, and implantation of devices (and systems thereof) for enabling such functionality. In some embodiments, a device is configured for implantation in a body vessel including fluid flow. The device may assume, or be constrained to assume, an un-deployed state and a deployed state. In the un-deployed state, the device or a portion thereof is configured to reside in the lumen of a thin needle or cannula having a diameter of less than about 0.5 mm (for example). The needle may include a curved portion, fix the deployed state, the device has an axis which, when implanted, is positioned approximately parallel to the fluid flow of the vessel. In some embodiments, the device comprises a thin filament body whereby in a deployed state, at least a portion of the filament takes on a helical shape. In some embodiments, at least one helix coil has height or pitch greater than the coil diameter.
