Abstract: An embolic filter is provided with a support frame and a porous polymeric membrane connected to the support frame. The embolic filter is configured to be movable between a collapsed state and a deployed state where the filter extends, in use, into contact with an inner wall of a patient's vasculature. The support frame of the embolic filter includes a shape memory material such that the support frame acts as a deployment arrangement to move the embolic filter from the collapsed state into the deployed state.

Abstract: A delivery catheter system includes a catheter and an integrated embolic filter that is deployable prior to the delivery of a prosthesis in a patient's vasculature and retrievable after delivery of said prosthesis. The embolic filter is moveable from a collapsed state, in which the embolic filter is retained within the catheter body, to a deployed state in which the embolic filter extends from the catheter body and, in use, into contact with an inner wall of a patient's vasculature.
