Abstract
Distal protection devices (“DPDs”) and methods of use thereof for capturing and removing vascular debris are provided. The DPD may include a catheter having a distal region sized and shaped to be advanced in a target vessel of the patient. The distal region of the catheter may include a filter basket and fibrous filter disposed thereon, the fibrous filter upstream of the filter basket. The fibrous filter and the filter basket may both transition between a collapsed delivery state and an expanded deployed state. For example, the fibrous filter may be made of a frame coupled to a plurality of fibers, and may exhibit a helical shape in its expanded state such that the plurality of fibers capture and store vascular debris within the blood vessel. The filter basket may capture any vascular debris not captured by the fibrous filter, and may be collapsed and removed from the patient while retaining the vascular debris.
