Abstract: Embodiments of the present disclosure are directed to systems, methods and devices for providing, in some embodiments, embolic protection in a patient. For example, a medical device and implantation method for implanting a medical device within a blood vessel of a subject are provided and comprise, for example, providing a medical device configured for arrangement within a blood vessel, where the device comprises a filament configured to include a first device end (posterior) and a second device end (anterior), an un-deployed state including at least a portion configured to fit within a lumen of a needle, and a deployed state wherein the filament automatically forms a helix wound in a first direction as viewed from the first device end to the second device end, the helix optionally including at least one of a support portion and a filter portion.

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.

Abstract: Embodiments of the invention are directed to systems, methods and devices for sustained medical infusion with controlled rate injection of a fluid into a body. Such a system may include a first separate reusable unit, a second separate depletable unit a third separate disposable unit having a cannula, and may include a fourth separate remote control unit. Emission of appropriate instructions from the fourth unit, when the first unit, the second unit, and the third unit are coupled together in associative operation and disposed on the skin, power is supplied to an engine for generating motion to a fluid transfer system, and when the cannula is inserted in the body, fluid is transferred from the reservoir to the body, via the tube and the cannula.
