Abstract:
1. An embolic protection device for filtering emboli in a body vessel, the device comprising: a filter having a plurality of openings formed therethrough, the filter having an expanded state and a collapsed state, wherein the filter has a proximal expandable end and a distal non-expandable end; a delivery element comprising a delivery sleeve, the delivery sleeve configured to be movable with respect to the filter between a delivery position, where the delivery sleeve is disposed about at least a portion of the filter so that the filter is in the collapsed state, and a non-delivery position, where the delivery sleeve is located proximally from the proximal expandable end of the filter, the delivery sleeve having a proximal end and a distal end, each of the proximal and distal ends of the delivery sleeve having a first position in the delivery position and a second position in the non-delivery position; and an extraction element separate from the delivery sleeve and configured to be movable with the filter and independently of the filter between a non-extraction position, where the extraction element is located distally of the distal non-expandable end of the filter, and an extraction position, where the extraction element is disposed around at least a portion of the filter so that the filter is in the collapsed state, the extraction element including a proximal end and a distal end, each of the proximal and distal ends of the extraction element having a first position in the non-extraction position and a second position in the extraction position, the extraction element being movable relative to the delivery sleeve, wherein the extraction element is located distally from the filter when the delivery sleeve is disposed about at least a portion of the filter and wherein the delivery sleeve is located proximally from the filter when the extraction element is disposed around at least a portion of the filter.
