Patent ID: 7850708

Claim:
An embolic protection device for capturing emboli during treatment of a stenotic lesion in a body vessel, the device comprising: a basket having a deployed state and an undeployed state, the basket including a reticulated body having an outer diameter, the reticulated body including a plurality of struts connected together in a singly staggered configuration relative to a longitudinal axis of the basket, the singly staggered configuration of the plurality of struts extending distally from a proximal end of the reticulated body along the longitudinal axis to a distal end, the plurality of struts being connected together at pivotal joints along the reticulated body, each pivotal joint connecting a pair of struts, wherein the number of pivotal joints singly increases distally along the longitudinal axis between the proximal and distal ends to define the singly staggered configuration of the plurality of struts, wherein the reticulated body in the undeployed state distally increases in width in the singly staggered configuration, the distal end defining the greatest width in the undeployed state, the pairs of struts connected by the pivotal joints being configured to singly fold distally along the longitudinal axis from the deployed state to the undeployed state, the basket having a proximal stem proximally extending from the body; and a filter portion having a lip attached to the distal end defining an opening of the filter portion when the basket is in the deployed state for capturing emboli, the filter portion extending from the lip to a filter end.
