Abstract:
1. An embolic filter device, comprising: a deployment sheath having a longitudinal axis; a frame having a delivery configuration and a deployed configuration, the frame comprising a first frame portion and a second frame portion; a first filter portion coupled to the first frame portion and a second filter portion coupled to the second frame portion wherein the first and second filter portions each have an open portion and a closed portion, wherein the open portion is adapted to allow foreign particles to pass therethrough and the closed portion is adapted to trap foreign particles therein; wherein the first and second frame portions pivot about a joint positioned between the first and second frame portions closest to each other, an axis of the joint extending substantially perpendicular to the longitudinal axis of the deployment sheath, thereby pivoting the open portions of the first and second filter portions towards one another about the axis and reconfiguring the frame into the delivery configuration in which the open portions of the first and second filter portions face each other and wherein in the deployed configuration the first and second frame portions are substantially perpendicular to the position of the first and second frames in the delivery configuration and wherein the open portions face away from the deployment sheath in the deployed configuration.
