Abstract:
Embodiments of the present disclosure are directed to systems, methods and devices 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. In 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. In some embodiments, the device has a monofilament filter portion including at least one coil whose center is off the helix axis. The device may be made of a super-elastic alloy so that the device can transition between the un-deployed and the deployed states without plastic deformation (in at least some embodiments). In some embodiments, the device is configured for transcatheter delivery.

Claim (Index 1):
An embolic protection device (EPD) configured for arrangement within a blood vessel, the EPD comprising:\n a filament configured to include:\n an un-deployed state including a portion configured to fit within a lumen of a needle or a tube; and \n a deployed state wherein the filament automatically forms a helix comprising a support portion, and a filter portion, \n wherein:\n the support portion comprises a first portion of the helix which includes an axis, comprising an elongated coil having a height which exceeds a diameter thereof and is configured to at least one of orientate the filter portion within a blood vessel and secure the EPD relative to the blood vessel, \n the filter portion includes a funnel configured to taper in a first direction, the funnel also including at least one reducing coil having a center which is off the axis, \n at least a portion of the elongated coil is configured to resist axial compression of the support portion, \n the reducing coil is configured to capture emboli greater than a predetermined size; \n and wherein the EPD further comprises at least one of:\n a stem, as part of the deployed shape, configured to traverse the vessel wall, \n a pull wire configured traverse a patient's skin and enable retraction of the device by pulling the device out of the vessel, \n a stopper configured to prevent the filament from moving from the vessel lumen outwards through a puncture in the vessel, \n an anchor configured to engage tissue externally to the vessel lumen, \n a second support portion, such that the filter portion is interposed between the support portion and the second support portion, \n and \n a second reducing coil whose center is off the axis.
