Abstract
Vascular filters and deflectors and methods for filtering bodily fluids. A blood filtering assembly can capture embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature. A blood deflecting assembly can deflect embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature.
Claims1
An embolic material protection device configured to inhibit embolic material from entering cerebral vasculature through a left vertebral artery, the device comprising:
- an outer sheath;
- an inner member radially inward of the outer sheath, the inner member comprising a guidewire lumen, the inner member trackable over a guidewire;
- and
- a self-expanding filter assembly radially between the outer sheath and the inner member, the self-expanding filter assembly being deployable out of the outer sheath by at least one of proximally retracting the outer sheath and distally advancing the self-expanding filter assembly, the self-expanding filter assembly comprising:
- a frame;
- and
- a filter element coupled to the frame,
- the inner member longitudinally movable independent of the self-expanding filter assembly and the outer sheath.
